Abstract:
Lauraceae is a group of tropical plants with a wide distribution. The abundance and species richness of the Lauraceae family includes the under to the upper canopy of the forest. The Lauraceae family can be utilized in various sectors, especially economically. Limiting characters as a significance in the Lauraceae classification was needed to provide additional information regarding taxon grouping. This research aimed to study epidermal characteristics, leaf venation variations, and the diversity of Lauraceae species under different forest environmental conditions. The research procedure involved: collecting ecological field data and morphological identification using a purposive sampling method based on the presence of species. Soil sampling and environmental microclimate were measured on each plot. The anatomical process was carried out by recording characters. Correlation between environmental factors and plant targets used canonical correspondence analysis. The kinship between members of Lauraceae was expressed in a dendrogram. The result of this study showed that Lauraceae could live at various elevations. The analysis data indicated differences in environmental factors that affect the existence of Lauraceae species. Leaf venation studies support clustering in the family using characters such as primary, secondary, tertiary veins, and areola. Observation of leaf venation can be used as a taxonomic significance in the family Lauraceae. Epidermal cell walls in leaf samples are straight, curved shallow, deep, and sharp. Other characters that can be found are anomocytic, laterocytic, and brachyparasitic types of stomata, with stellate and glandless trichomes The anatomical dendrogram separated Lauraceae into clusters on a similarity coefficient scale.

Abstract:
Lauraceae is a large family of woody plants with high ecological and economic value. The tribal and generic division and phylogenetic relationship of Lauraceae have long been controversial. Based on morphological and molecular evidence, phylogenetic relationships within the Cinnamomeae, Laureae and Perseeae tribes, also called ‘the Core Lauraceae’, have arisen particular attention. In this review, we comprehensively collated the literatures on the phylogeny of Lauraceae published in recent years and summarized progress made in molecular systematic researches employing gene fragments, chloroplast genomes and DNA barcodings analyses. We clarified the phylogenetic relationships and main controversies of ‘the Core Lauraceae’, the systemic position of fuzzy genera (Neocinnamomum, Caryodaphnopsis and Cassytha) and the development of chloroplast genome and DNA barcodes. We further suggested and proposed the whole genome analysis and different inflorescence types would be possible to provide more information for further research on phylogenetic relationships and taxonomy of Lauraceae.

Generic delimitations among the Asian members of the Persea group, including the recently described genus Alseodaphnopsis, are discussed. These genera, with the exception of Alseodaphnopsis, are characterized by reproductive characters. A study of flowers of Alseodaphnopsis species found that Alseodaphnopsis species have unisexual flowers and that Alseodaphnopsis is better defined by its unisexual flowers than by vegetative characters. This is the first report of the presence of unisexual flowers in any member of the Persea group.

Abstract:
Keluarga Medang-medangan (Famili Lauraceae) merupakan salah satu kelompok tumbuhan yang banyak ditemukan di daerah tropis. Lauraceae juga termasuk kelompok yang paling banyak dimanfaatkan dan bernilai ekonomi tinggi. Pemanfaatan intensif dan nilai ekonomi yang tinggi tidak diimbangi dengan usaha konservasi yang memadai membuat Famili Lauraceae menjadi rentan dalam kepunahan. Permasalahan yang muncul dari keinginan untuk melakukan konservasi bagi Famili Lauraceae adalah sangat minimnya pengetahuan tentang jenis serta nama ilmiah yang benar. Taman Hutan Kota Muhammad Sabki merupakan hutan kota yang diperlukan karena fungsinya antara lain memperbaiki dan menjaga iklim mikro dan nilai estetika, meresapkan air, menciptakan kesimbangan dan keserasian lingkungan fisik kota, dan mendukung pelestarian keanekaragaman hayati di Indonesia. Peneliti tertarik untuk melakukan eksplorasi botani dan identifikasi terhadap keanekaragaman jenis famili Lauraceae yang berada di taman hutan kota Muhammad Sabki. Penelitian dilakukan ada bulan Agustus-Oktober 2017 di taman Hutan Kota M. Sabki. Kesimpulan yang dapat diambil dari penelitian ini adalah anggota family Lauraceae di Hutan Kota M. Sabki ditemukan berjumlah 12 spesies dengan indeks keanekaragaman Shannon-Wiener 2,36.

Abstract:
AbstractThe Lauraceae family is predominantly found in Asia and in the rainforests of the Americas, and consists mostly of aromatic trees. Being an essential oil producer, this family is used in the food, pharmaceutical, and cosmetic industries. This work presents a systematic review of the chemical composition and bioactivity of the essential oils from the Lauraceae family. Medline, Scielo, Web of Science, Lilacs, and Scopus were employed to identify articles published between 2000 and 2018, using “Lauraceae”, “essential oil”, and “biological activity” as key words. From 177 studies identified, 53 met the inclusion criteria. These studies indicated a predominance of the compounds β-caryophyllene and 1,8-cineole in Lauraceae species, and highlighted the antioxidant, antifungal, antibacterial, and anti-inflammatory activities. Essential oils extracted from this family thus have high potential for pharmacological applications.

Abstract:
Abordagens como homologia, construção de táxons e reconstrução da filogenia podem ser contextualizadas e investigadas por meio de uma conexão histórica e atual entre sistemática e filosofia. A presente tese defende essa conexão científico-filosófica, tendo como estudo de caso ambos o complexo Ocotea, que abrange 13 gêneros e 750 espécies predominantemente neotropicais, e o grupo Ocotea indecora, com 20 espécies e centro de diversidade na floresta atlântica do sudeste do Brasil. O capítulo 1 discute a conceitualização de táxons e homologias (táxica e transformativa) como ambos indivíduos e espécies naturais (ou agrupamentos de espécies com propriedade homeostática). Embora essas conceitualizações não sejam mutuamente exclusivas metafisicamente, a perspectiva das espécies naturais é defendida, enquanto a dos indivíduos desafiada, com base em uma motivação por aspectos empírico-pragmáticos e teórico-explicativos em sistemática e evolução. O capítulo 2 foca no renascimento da morfologia na sistemática filogenética, com base em duas teorias da verdade em epistemologia, i.e., coerência e correspondência, chamando para a unificação de ambas a teorias partir de uma teoria funderentista de justificação epistêmica das hipóteses de relação filogenética. O papel e o significado da morfologia também são discutidos no contexto de análises separadas e combinadas, paleontologia, espécies naturais, conceito de caráter, homologia, sinapomorfia, semaforonte, modularidade e taxonomia. O renascimento da morfologia não é apenas dependente de uma perspectiva científico-filosófica mas também depende de uma reforma política, econômica, social e educacional na sistemática contemporânea. O capítulo 3 é uma filogenia do complexo Ocotea com análise combinada de dados morfológicos e da região nuclear ribossômica ITS. São discutidos o papel e o significado das evidências morfológica e molecular, das análises separadas e combinadas, bem como modularidade e homologia. Subclados dentro do complexo Ocotea são inferidos e delimitados por sinapomorfias morfológicas. Uma perspectiva de classificação filogenética dos gêneros do complexo Ocotea também é fornecida. O capítulo 4 trata de mudanças taxonômicas e nomenclaturais no grupo O. indecora, basicamente sinonimizações, lectotopificações e uma nova combinação. O capítulo 5 é uma revisão do grupo O. indecora, com base na análise de ca. 550 coleções. Chave de identificação, descrições, bem como comentários sobre a circunscrição, distribuição, habitat, fenologia e relações taxonômicas das espécies do grupo são fornecidos.
Approaches as homology, construction of taxa, and phylogeny reconstruction can be contextualized and investigated through a historical and current connection between systematics and philosophy. The present thesis defends this scientific-philosophical connection, having as study case both the Ocotea complex, which embraces 13 genera and 750 species predominantly Neotropical, and the Ocotea indecora group, with 20 species and centre of diversity in the Atlantic forest from Southeastern Brazil. The chapter 1 discusses the conceptualization of taxa and homologies (taxic and transformative) as both individuals and natural kinds (or homeostatic property cluster kinds). Although these conceptualizations are not mutually exclusive metaphysically, the perspective of natural kinds is endorsed, whereas that of individuals challenged, based on the motivation for empirical-pragmatic and theoretical-explanatory aspects in systematics and evolution. The chapter 2 focuses on the renaissance of morphology in phylogenetic systematics based on two theories of truth in epistemology, i.e., coherence and correspondence, calling for a unification of both theories from a fundherentist theory of epistemic justification of hypotheses of phylogenetic relationship. The role and meaning of morphology are also discussed in the context of separate and combined analyses, paleontology, natural kinds, character concept, homology, synapomorphy, semaphoront, modularity, and taxonomy. The renaissance of morphology is not only dependent on a scientific-philosophical perspective but it is also dependent on a political, economic, social, and educational reform in contemporary systematics. The chapter 3 is a phylogeny of the Ocotea complex with combined analysis of morphology and ITS nuclear ribosomal region. The role and meaning of morphological and molecular evidence, separate and combined analyses, as well as modularity and homology are discussed. Subclades within the Ocotea complex are inferred and delimited by morphological synapomorphies. A perspective of phylogenetic classification of the genera of the Ocotea complex is provided. The chapter 4 treats of taxonomic and nomenclatural changes in the O. indecora group, basically synonyms, lectotypifications, and a new combination. The chapter 5 is a revision of O. indecora group based on the analysis of ca. 550 collections. Identification key, descriptions, as well as comments on its circumscription, distribution, habitat, phenology, and taxonomic relationships of its species are provided.

Abstract:
Este trabalho teve como objetivo testar o monofiletismo de Mezilaurus e a relação deste com os gêneros do \"grupo Mezilaurus\" (sensu Rohwer & Rudolph 2005), incluindo um número maior de táxons do que os tratamentos anteriores, além de revisar os limites morfológicos entre as espécies deste gênero. O \"grupo Mezilaurus\" (sensu Rohwer & Rudolph 2005), emergiu em filogenias prévias como monofilético, composto pelos gêneros Anaueria, Chlorocardium, Mezilaurus, Sextonia e Williamodendron. O trabalho baseou-se em sequências dos marcadores moleculares trnH-psbA e ITS de nove espécies de Mezilaurus e 15 espécies de grupos-externos. Análises de Parcimônia e Bayesiana foram empregadas com os marcadores separadamente e combinados. Os resultados obtidos demonstraram o \"grupo Mezilaurus\" como não monofilético e posicionamento incerto de Chlorocardium e Anaueria. Os Mezilauroides (sensu Rohwer & Rudolph 2005), com Mezilaurus, Sextonia e Williamodendron emergiu como monofilético, entretanto, o gênero Mezilaurus, atualmente circunscrito, não é monofilético e, uma de suas espécies, M. mahuba, surgiu como grupo-irmão de Sextonia. Por essa razão, a espécie foi removida de Mezilaurus e restabelecida como Clinostemon. Com base nessa nova circunscrição, foram realizadas as revisões taxonômicas de Mezilaurus e Clinostemon, baseadas em coleta de material botânico em expedições de campo e análises de aproximadamente 550 espécimes de exsicatas, oriundas de cerca de 60 herbários. Mezilaurus (15 espécies) e Clinostemon (1 espécie) compartilham folhas congestas no ápice dos ramos, produto de seu crescimento rítmico apositivo, flores bissexuadas, três estames férteis, representando a terceira série do androceu, anteras biloceladas e fruto com cúpula de pateliforme a plana com tépalas persistentes. Clinostemon, entretanto, apresenta anteras encurvadas e um par de glândulas nos filetes. Foram realizadas sinonimizações, lectotipificações e a descrições de quatro novas espécies de Mezilaurus para a ciência, elaboradas chaves de identificação, descrições morfológicas, além de comentários taxonômicos, fenológicos e de conservação e disponibilizadas ilustrações das espécies dos dois gêneros.
This study aimed to test the monophyletism of Mezilaurus and its relation within the \"Mezilaurus group\" clade (sensu Rohwer & Rudolph 2005), including more taxa than the previous treatments, and to revise the morphological boundaries between the species of the genus. The \"Mezilaurus group\" had emerged as monophyletic in previous phylogenies, with Anaueria, Chlorocardium, Mezilaurus, Sextonia, and Williamodendron. The work was based in the molecular markers trnH-psbA and ITS of nine Mezilaurus species, and 15 species from the outgroup. Parsimony and Bayesian analysis were performed with the markers both separately and combined. The results demonstrate that the \"Mezilaurus group\" is not monophyletic and uncertain position of Chlorocardium and Anaueria. The Mezilauroids, containing Mezilaurus, Sextonia, and Williamodendron, arose as monophyletic, although the Mezilaurus genus, as currently defined, is not monophyletic and M. mahuba emerged as sister of Sextonia. Therefore, it was necessary to remove M. mahuba of its circumscription, and reinstate this species as Clinostemon. Based on this circunscription, were carried out the taxonomic revisions of Mezilaurus and Clinostemon, based on collecting botanical specimens in expeditions, and analisys of 550 specimens of exsiccates from about 60 herbaria. Mezilaurus (15 species) and Clinostemon (1 species) have rythmic branching with distally clustered leaves, bisexual flowers, three fertile stamens, representing the third androecial whorl, 2-locular anthers, fruit with a minute discoid cupule, and persistent tepals. However, Clinostemon has recurved anters and one par of glands at the base of filaments. Synonymizations, lectotypifications, description of four new species of Mezilaurus to science, keys, morphologic descriptions, fenological aspects and conservation, taxonomic commentaries and ilustrations are presented for the two genera.

A Riparina I é uma alcamida isolada do fruto não maduro da Aniba riparia. Estudos prévios demonstraram que dois de seus análogos estruturais, as Riparinas II e III, desencadeiam ações ansiolíticas e antidepressivas em modelos animais clássicos. A fim de contribuir com a busca por melhores alternativas terapêuticas para os tratamentos da ansiedade, depressão e convulsão em humanos, investigou-se os efeitos centrais da Riparina I em camundongos. Para tanto, utilizou-se modelos clássicos de triagem de agentes sedativo/hipnóticos, antidepressivos e anticonvulsivantes: Campo Aberto (CA), Rota Rod (RR), Labirinto em Cruz Elevado (LCE), Placa Perfurada(PP), Suspensão da Cauda (SC), Nado Forçado (NF), Tempo de Sono induzido por Pentobarbital (TSP) e Convulsão induzida por Pentilenotetrazol (CP). Para estes testes, os animais receberam administração aguda de Riparina I, doses 25 ou 50 mg/kg, por vias oral ou intraperitoneal. Demonstrou-se que a administração da substância teste nas doses de 25 e 50 mg/kg produziu um efeito ansiolítico, anticonvulsivante e potencializador do tempo de sono barbitúrico e que nestas mesmas doses não apresentou efeito estimulante motor ou relaxante muscular. Além disso, a Riparina I causou um efeito antidepressivo em dois modelos animais clássicos preditivos de propriedades antidepressivas (TSC e TNF), não relacionado a um efeito psicoestimulante, e que parece ser mediado, pelo menos em parte, por uma interação com os sistemas dopaminérgico (receptores D1 e D2), noradrenérgico (receptores α1 e α2) e serotoninérgico (receptores 5-HT2A/2C). Esse estudo fornece evidências experimentais e abre perspectivas para estudos posteriores que podem culminar com uma futura utilização terapêutica da Riparina I no tratamento da depressão, ansiedade, insônia e convulsão. Entretanto, estudos posteriores mais aprofundados far-se-ão necessários para confirmar os mecanismos envolvidos nos efeitos apresentados.

Depression is a disabling and recurrent disease whose clinical treatment is related to modulations in monoaminergic systems in various brain areas. Riparina II (ripII), alkamide isolated from unripe fruit of Aniba riparia, has shown previously antidepressant-like effects in animal behavioral models. Thus, in order to investigate the potential antidepressant ripII, behavioral experiments were performed as the forced swim, tail suspension and open field tests. To assess the involvement of monoaminergic system, animals were pretreated with specific antagonists to 5-HT1A-, 5-HT2A/2C-, and 5-HT3-serotonin (5-HT) receptors, to D1- and D2-dopamine (DA) receptors and to 1- and 2-noradrenaline (NA) receptors in the forced swimming test. Furthermore, animals pretreated with ripII and submitted to the forced swim test had their brain areas such as hippocampus, striatum and prefrontal cortex removed for detection of monoamine levels in HPLC electrochemical or to carry out the experiments of oxidative stress. In the oxidative stress assays we investigated enzymatic activities of superoxide dismutase, measured the levels of reduced glutathione (GSH) and nitrite/nitrate, and lipid peroxidation degree. RipII was acutely administered orally at a dose of 50 mg/kg in all tests. The results showed that ripII presented antidepressant effect on the forced swim and tail suspension tests suggesting that this effect is specific, since the animals showed no changes in locomotor activity in open field test. In the evaluation of monoaminergic systems, the results showed that the antagonists SCH23390 (D1), sulpiride (D2), prazosin (1), NAN-190 (5-HT1A) and ondansentron (5-HT3) reversed the immobility time of ripII on the forced swim test suggesting the involvement of these receptors for the antidepressant effect of ripII, while no change of this effect in the presence of the antagonists yohimbine (2) and ritanserin (5-HT2A/2C) was observed, suggesting non-participation of these receptors on the drug effect. The prior administration of ripII before the forced swimming, reversed the increased levels of lipid peroxidation and increased levels of GSH in hippocampus, striatum and prefrontal cortex. In conclusion, the study suggests a modulating action exerted by ripII on the functioning of the noradrenergic, dopaminergic and serotonergic levels in the brain, as a mechanism for the antidepressant effect in the forced swimming test, as well as the participation of direct or indirect antioxidant properties of this drug through the ability to modify the neuronal response to oxidative stress.
A depressão é uma doença recorrente e incapacitante cujo tratamento clínico está relacionado com modulações nos sistemas monoaminérgicos em diversas áreas cerebrais. A riparina II (ripII), alcamida isolada do fruto verde de Aniba riparia, apresentou previamente efeito antidepressivo em modelos comportamentais. Dessa forma, objetivando investigar o potencial antidepressivo da ripII, foram realizados experimentos comportamentais como o teste do nado forçado, suspensão da cauda e campo aberto. Para avaliar o envolvimento do sistema monoaminérgico, os animais foram pré-tratados com antagonistas específicos para receptores 5-HT1A, 5-HT2A/2C e 5-HT3 de serotonina (5-HT), D1 e D2 de dopamina (DA) e a1 e a2 de noradrenalina (NA) no teste do nado forçado. Além disso, os animais previamente tratados com ripII e submetidos ao teste do nado forçado tiveram as áreas cerebrais hipocampo, corpo estriado e córtex pré-frontal retiradas para detecção dos níveis de monoaminas em HPLC eletroquímico ou para realização dos experimentos de estresse oxidativo, para o qual foram investigadas a atividade enzimática da superóxido dismutase, quantificação dos níveis de glutationa reduzida (GSH) e nitrito/nitrato, além do grau de lipoperoxidação. A ripII foi administrada agudamente, por via oral, na dose de 50 mg/kg, em todos os testes realizados. Os resultados mostraram que a ripII apresentou efeito antidepressivo nos modelos de nado forçado e suspensão da cauda sugerindo que este efeito seja específico, uma vez que os animais não apresentaram alterações na atividade locomotora no teste do campo aberto. Na avaliação dos sistemas monoaminérgicos, os resultados mostraram que os antagonistas SCH23390 (D1), sulpirida (D2), prazosina (a1), NAN-190 (5-HT1A) e ondansentron (5-HT3) reverteram o tempo de imobilidade da ripII no nado forçado sugerindo a participação desses receptores para o efeito antidepressivo da substância, enquanto não houve alteração deste efeito na presença dos antagonistas ioimbina (a2) e ritanserina (5-HT2A/2C) sugerindo a não participação desses receptores no efeito da droga. A administração prévia de ripII, antes do nado forçado, reverteu o aumento nos níveis de peroxidação lipídica, mas aumentou os níveis de GSH em hipocampo, corpo estriado e córtex pré-frontal. Em conclusão, o estudo sugere uma ação moduladora, exercida por ripII, sobre o funcionamento dos sistemas noradrenérgico, dopaminérgico e serotonérgico, em nível central, como mecanismo para o efeito antidepressivo no teste do nado forçado, bem como a participação de propriedades antioxidantes diretas ou indiretas dessa droga, através da capacidade de modificar a resposta ao estresse oxidativo neuronal.

Abstract:
Laurus nobilis l. , plante aromatique principalement etudiee pour l'huile essentielle de ses feuilles, a fait l'objet lors de nos travaux, d'une nouvelle etude phytochimique. Celle-ci a ete motivee, dans un premier temps, par les resultats d'un criblage systematique d'activite cytotoxique revelant l'activite d'un extrait brut de feuilles de laurus nobilis l. Deux alcaloides aporphiniques, la cryptodorine et l'actinodaphnine, se sont reveles responsables de cette cytotoxicite in vitro mais ils sont inactifs in vivo. Dans un deuxieme temps, les connaissances deja acquises sur la composition de l'huile essentielle de cette plante ont ete completees par l'etude de l'huile essentielle des fleurs et de celle des racines, jusque la, non decrites. L'huile essentielle des fleurs est principalement constituee des composes suivants: l'ocimene e, le b-caryophyllene, le viridiflorene, le b-elemene, le germacradienol et le germacrene d. Au niveau des racines, aucun composant majoritaire n'emerge de l'huile essentielle des ecorces de racines, seulement constituee de monoterpenes et de sesquiterpenes oxygenes ou non. L'huile essentielle du bois de racines se caracterise par une teneur elevee en sesquiterpenes et par la quasi absence de monoterpenes. Enfin, l'etude de la composition flavonoidique des feuilles a permis l'isolement de dix-huit flavonoides. Quatre sont des produits relativement originaux, n'ayant jamsi ete decrits dans le laurier sauce (derives acyles du kaempferol)

Lauraceae é uma Família de Magnoliophyta com distribuição marcadamente tropical e subtropical em todo o mundo, especialmente nas florestas centro e sul-americana. No Brasil, a família Lauraceae possui uma distribuição muito extensa, sendo encontrada nas mais diversas regiões, estando presente nas restingas do litoral, nos cerrados e nas matas, compreendendo cerca de 2.000 espécies. Ocotea Aublet é o maior gênero em número de espécies dentro da família, apresentando cerca de 400 espécies, distribuindo-se principalmente na América do Sul e América Central e em menor grau, no oeste da África e Madagascar. Ocotea apresenta grande importância econômica, destacando-se inúmeras espécies usadas na indústria madeireira, ou como produtoras de óleo usado na indústria farmacêutica e na medicina. Não obstante a importância do gênero no contexto econômico e ecológico, o uso irracional destes recursos naturais levou inúmeras espécies quase a extinção, entre as quais Ocotea odorifera (Vell.) Rohwer. Os caracteres morfológicos do grupo são muito homogêneos, e sua utilização, para a delimitação e determinação das relações entre os taxa, é limitada. No presente trabalho são apresentadas as características anatômicas da madeira de O. odorifera. Foi analisado o lenho de quatro árvores coletadas em ambientes distintos, nos municípios de Rancho Queimado/SC e Florianópolis/SC, em ambientes de Floresta Ombrófila Mista e Floresta Ombrófila Densa, respectivamente. As amostras de lenho avaliadas não apresentaram diferenças anatômicas entre si e todas as características anatômicas descritas para a Família Lauraceae foram observadas no lenho de O. odorifera. Presença de tilos no interior dos elementos de vaso, tanto em cerne, como em alburno foram observados. Células de óleo são abundantes no xilema e também no floema. Cristais rombóides e estilóides foram encontrados no interior de células do parênquima. Cristais rombóides foram encontrados no interior de fibras.

Abstract:
Tea tree oil (TTO) is the essential oil of tea tree (Melaleuca alternifolia or M. linariifolia, Myrtaceae). Adulteration of TTO has become more apparent in recent years. Adulteration occurs with single essential oil components (e.g., sabinene from pine oil), waste products derived from other essential oils such as pine (Pinus spp., Pinaceae), eucalyptus (Eucalyptus globulus and other Eucalyptus spp., Myrtaceae), and camphor (Cinnamomum camphora, Lauraceae) oils, or with essential oils from other Melaleuca species and the closely related genus Leptospermum. This Laboratory Guidance Document presents a review of the various analytical technologies used to differentiate between authentic tea tree oil and essential oils containing adulterating materials. This document can be used in conjunction with the Tea Tree Oil Botanical Adulterants Bulletin published by the ABC-AHP-NCNPR Botanical Adulterants Prevention Program in 2017.
