Resumen
When preparing the Illustrated Flora of Taiwan, we noticed that new combinations are necessary for two endemic species in family Polygonaceae Jussieu (1789: 82), Polygonum pilushanense Y.C.Liu & C.H.Ou in Ou (1976: 123) and P. yatagaianum Mori (1937: 25), to fit recently revised taxonomic framework (Sanchez et al. 2009, 2011, Schuster et al. 2011, 2015). Brief notes on their taxonomic positions are also provided.

Resumen
Mount Fansipan, situated in the Hoang Lien Son Range, supports a rich subtropical and temperate flora of over 1700 species, including 25% of Vietnam’s endemic plant taxa (Nguyen & Harder 1996, Sterling et al. 2006). At elevations above 2000 m, Mount Fansipan contains numerous temperate genera including Acer Linnaeus (19 spp., Sapindaceae Jussieu), Alnus Miller (A. nepalensis, Betulaceae Gray), Betula Linnaeus (B. alnoides Buchanan-Hamilton, Betulaceae), Carex Linnaeus (36 spp., Cyperaceae Jussieu), Clematis Linnaeus (9 spp., Ranunculaceae Jussieu), Lithocarpus Blume (13 spp., Fagaceae Dumortier), Quercus Linnaeus (9 spp., Fagaceae), Rhododendron Linnaeus (40 spp., Ericaceae Jussieu), Rubus Linnaeus (36 spp., Rosaceae Jussieu), Tsuga Carrière (T. dumosa Eichler, Pinaceae Sprengel ex F. Rudolphi), Ulmus Linnaeus (U. lancifolia Roxburgh, Ulmaceae Mirbel), Vaccinium Linnaeus (12 spp., Ericaceae), and Viola Linnaeus (12 spp., Violaceae Batsch) (Vietnam Plant Data Center 2015, Nguyen & Harder 1996) with many of these genera being both species-rich and locally common (Nguyen & Harder 1996, pers. obs.). In April 2012, a collection of a specimen, representing the temperate genus Luzula de Candolle (1805: 158), was made while conducting botanical studies on the Carex flora of Mount Fansipan, Lao Cai Province, Vietnam, which is about 30 km south of the border with Yunnan Province, China. While the specimen was immediately recognized as a Luzula, a new genus to the flora of Vietnam (Vietnam Plant Data Center 2015), it was not until our collection was identified using the keys in Wu & Clements (2000) and Kirschner (2002) that it was determined to be Luzula effusa Buchenau (1879: 88) (Figs. 1, 2). A Basic Alignment Search Tool (BLAST) search of an internal transcribed spacer region (ITS1+5.8S+ITS2) sequence obtained from our specimen (KM612280) showed a 100% match with an existing sequence for L. effusa var. chinensis (Brown 1903: 161) Wu (1992: 92) (AY727778.1, see Drábková & Vlcek 2010) in GenBank (National Center for Biotechnology Information 2014), supporting our identification based on morphology (Table 1). Eighteen other Luzula accessions, representing species placed in two different subgenera and four different sections, were found to have 100% coverage and 99% identity with the sequence from our specimen (National Center for Biotechnology Information 2014) (Table 1). In all cases, these sequences came from taxa that occur in regions that are more geographically disparate from Vietnam than the previously known closest location for L. effusa (see below). These taxa are also morphologically dissimilar to our specimen (see text below and Table 1).

Resumen
Rumex obtusifolius L. (Polygonaceae), commonly known as 'broad-leaf dock', is one of the most common Irish wayside weeds, and it also occurs in silage fields, on river banks, in ditches and on waste grounds. The ethnobotanical uses of this species include its use as an antidote to nettle, depurative, astringent, laxative, and tonic, and in the treatment of sores, blisters, burns, cancer and tumors. The bioactivities of n-hexane, dichloromethane (DCM) and methanol (MeOH) extracts of the leaves of R. obtusifolius were assessed using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, the newly developed micro-titer-based antimicrobial assay incorporating resazurin as an indicator of cell growth, and the brine shrimp lethality assay. The most potent free radical scavenging activity was displayed by the MeOH extract with a RC50 value of 7.80 x 10-2 mg/mL. Among the fractions obtained from solid-phase extraction (SPE) of the MeOH extract, the 50% aqueous methanolic SPE fraction exhibited the highest levels of free radical scavenging property (RC50 = 1.05 x 10-2 mg/mL). While the n-hexane extract did not show any antibacterial activity at test concentrations, the DCM extract was active only against Escherichia coli. However, the MeOH extract as well as the 50% and 80% SPE fractions of the MeOH extract showed significant antibacterial property against all bacterial strains tested. None of the extracts or fractions exhibited any significant toxicity towards brine shrimps.

Resumen
The flora of Latin America attracts gaining interest as it provides a plethora of still unexplored or underutilized fruits that can contribute to human well-being due to their nutritional value and their content of bioactive compounds. Antioxidant compounds are now of considerable interest due to their effect of preventing or delaying aging and their apparent involvement in prevention of numerous human diseases, including cancer, atherosclerosis, Alzheimer’s disease, inflammation, and rheumatoid arthritis. In this work, the fruit ofCoccoloba uvifera(L.) was investigated for theirin vitroantioxidant capacity using two assays based on reactions with a relatively stable single reagent radical (Trolox equivalent antioxidant capacity, TEAC; and DPPH free radical scavenging assay, DPPH), two assays based on chelating of metallic cations, and one based on the reduction of oxidized species. The TEAC value on ABTS radical, DPPH scavenging activity, ion chelation, and reducing power were found to be 897.6 μM of Trolox/100 g of sample, 22.8% of DPPH free radical scavenging, 11.3% of Cu2+-chelating activity, 23.9% of Fe2+-chelating activity, and a Fe2+-reducing power of 0.76 mg/mL, respectively. The free radical scavenging and antioxidant characteristics ofC. uviferamay be due to the presence of diverse phytochemicals in the fruit as anthocyanins, ascorbic acid, phenolic compounds, and flavonoids.

Resumen
A comparative macro- and micromorphological study was conducted on achenes of Korean Polygonaceae comprising 45 taxa under 10 genera using a Stereo-microscope (SM) and Scanning Electron Microscope (SEM) to evaluate the taxonomical relevance of achene morphological characteristics. The achene shape is lenticular, biconvex, trigonous, or spheroidal. The largest achenes are found in Fagopyrum esculentum Moench (5.80–6.70 × 3.90–4.40 mm) and Rheum rhabarbarum L. (5.00–6.50 × 4.00–5.20 mm), and the smallest is found in Rumex maritimus L. (1.17–1.41 × 0.60–0.84 mm). Three types of embryo shape (curved, straight, and folded) and two types of embryo position (plane and parietal) can be distinguished. Most taxa have a curved embryo shape with plane position. Four types of surface patterns (smooth, papillae, tuberculate, or small pits) are observed. The surface sculpture or embryo type is rather consistent at the generic or tribal level, and the comprehensive consideration of achene characteristics is also useful at the species level. The achene morphology is described in detail, compared, and illustrated. The taxonomic significance of the achene morphology is discussed.

Polygonum punctatum Elliot. pertenece a la familia Polygonaceae, la medicina popular le atribuye varias propiedades, por medio de estudios anteriores se confirma que diferentes extractos de esta planta presentan actividad antibacteriana, antiinflamatoria y antifúngica. En este trabajo, se evaluó la actividad citotóxica del extracto etanólico de Polygonum punctatum de la familia Polygonaceae en concentraciones de 100, 50 y 25 µg/ml en células de macrófagos de ratones, en los cuales no se encontró actividad citotóxica. Además, se evaluó la actividad leishmanicida por medio de estudios experimentales in vitro a concentraciones de 100, 75, 50, 25, 20 y 10 µg/ml frente a tres cepas de parásitos: Leishmania infantum, L. amazonensis y L. braziliensis, en los cuales se observó una actividad de 58 y 56% de lisis de parásitos con el extracto de 100µg/ml frente a las cepas de L. braziliensis y L. infantum, respectivamente y 51% para L. amazonensis. Estos resultados son prometedores, y aportan una base para el desarrollo y búsqueda de nuevos tratamientos para la leishmaniasis, sin embargo, son necesarios estudios posteriores en cuanto a aislamiento e identificación del compuesto y evaluación en modelos animales in vivo.

“… To the ground, With solemn adoration, down they cast Their crowns, inwove with amaranth and gold. Immortal amaranth, a flower which once In Paradise, fast by the tree of life, Began to bloom.”–John Milton (1608–1676), Paradise LostRedroot pigweed (Amaranthus retroflexus L.), one of the New World's major weeds, was described in 1753 by Carolus Linnaeus in Species Plantarum. Over three decades later (1789), the genu wa placed in Amaranthaceae by Antoine Laurent de Jussieu (1748–1836) (Britton and Brown 1898). Amaranthaceae belongs to Centrospermae, a group of familie that contain betalain pigments instead of the anthocyanins found in most other angiosperms; it is closely related to Chenopodiaceae (Heywood 1993).

Resumen
The review of materials on the composition and biological activity of anthraquinones of species of the genus Rheum L. The most well-studied are the representatives of "forest rhubarb", which evolved in the forests of Central and Northern China: Rheum palmatum L., R. officinale Baill., R. emodi Wall. ex Meissn., R. rhabarbarum L. (= R. undulatum L.) and R. compactum L. (= R. rhaponticum L.). The official rhubarb is the Tungut rhubarb R. palmatum L. var. tanguticum Regel, known on the international pharmaceutical market as "Chinese rhubarb". The main aglykones of rhubarb anthraquinones are chrysofanol, emodin, aloe-emodin, fisсion and rhein. Particular attention is paid to various aspects of their impact on the processes that accompany oncological diseases. Emodin was found to inhibit cell proliferation, induce apoptosis induction, and prevent metastases. Emodin and aloe-emodin have high cytotoxic activity against oral squamous cell carcinoma and salivary gland cancer. Rhein inhibits the absorption of glucose in tumor cells and leads to their death. Anthraquinone glycosides, in contrast to aglycons, exhibit moderate cytotoxic activity. Other types of biological activity have been investigated - antimicrobial, antiviral, immunomodulating, antioxidant, molluscicidal etc. It follows from the presented materials that species of the genus Rheum containing anthracene derivatives are promising for practical use and further study.

Resumen
The review provides information on the biological activity of 26 species of the genus Rumex L. based on the results of studies for the period of 2014-2019. Information search and scientometric analysis were carried out using the resources of the Scopus scientific database. The annual number of scientific publications related to plants of the genus Rumex persists at a fairly high level (more than 100 publications per year). It was found that the most studied species in terms of biological activity and composition are R. acetosa, R. crispus, R. dentatus, R. nervosus, R. obtusifolius, R. vesicarius, which showed the presence of antihypertensive, antiosteoporotic, antiviral, nephro- and hepatoprotective and other types of activity in pharmacological studies. Articles describing mechanisms of the extracts’ active substances’ biological effects are presented, but this information is fragmentary. The chemical composition has been studied mainly for officinal species. A number of species – R. alveolatus, R. aquaticus, R. conglomeratus, R. hastatus, R. lunaria, R. maritimus, R. occidentalis, etc. – are promising for further study as the various extracts of these plants showed antibacterial, cytoprotective, antitumor, antihyperglycemic activity, the ability to stimulate hair growth and fight hyperpigmentation.

Resumen
In 1789, the Annonaceae family was catalogued by de Jussieu. It encompasses tropical and subtropical plants which are widespread in distribution across various continents such as Asia, South and Central America, Australia and Africa. The genus of Annona is one of 120 genera of the Annonaceae family and contains more than 119 species of trees and shrubs. Most species are found in tropical America, where over 105 species have been identified. Due to its edible fruits and medicinal properties, Annona is the most studied genus of Annonaceae family. To date, only a limited number of these species have economic value, including A. squamosa L. (sugar apple), A. cherimola Mill. (Cherimoya), A. muricata L. (guanabana or soursop), A. atemoya Mabb. (atemoya), a hybrid between A. cherimola and A. squamosa, A. reticulata L. (custard apple), A. glabra L. (pond-apple) and A. macroprophyllata Donn. Sm. (ilama). Phytochemically, several classes of secondary metabolites, including acetogenins, essential oils, alkaloids, terpenoids and flavonoids. The pharmacological activities of Annona species leaves and seeds include antibacterial, anticancer, antidiabetic and anti-inflammatory properties.

Resumen
Methanolic extracts of 11 Rumex L. species (Polygonaceae) were examined against brine shrimp and R. scutatus L. has shown significant brine shrimp lethality (LC50=0.96 μg/ml). Methanolic extracts of the roots of R. scutatus were fractionated and the active fraction led to the isolation of 4 anthraquinone aglycones: emodin, chrysophanol, physcion and aloe emodin. Their toxic sequence was found as chrysophanol> aloe emodin> emodin> physcion. These anthraquinone aglycones showed a significant activity with LC50=0.00, LC50=0.01, LC50=0.05, LC50=0.15 μg/ml, respectively

Resumen
Background/Aim. Congenital malformations still represent one of the most important causes of prenatal and infant death. The study aim was to analyze occurrence, outcomes and risk factors of different types of congenital anomalies. Methods. The study included all pregnant women directed to Clinic of Obstetrics and Gynecology, Clinical Center of Serbia, Belgrade due to prenatally diagnosed congenital fetal anomalies during past ten years (January 1, 2008?December 31, 2017). Upon admission to our Clinic a detailed general medical and obstetrical history were taken from every patient. All women underwent genetic testing. Ultrasonography and magnetic resonance were diagnostic methods for fetal malformations confirmation. Results. The study included 773 pregnant women aged from 18 to 46 years. Out of registered nine different groups of fetal anomalies/malformations, the most common were malformations of the central nervous system, while majority of fetuses had combined multiple anomalies. Genetic cause for congenital anomalies was present in 25.2% of pregnancies. Medical pregnancy abortion was performed in 71.8% of cases. Only 10.2% of pregnancies ended in term. The best outcome for children was obtained in case of gastrointestinal anomalies (52% live born). Contrary, only one child with neck and thorax malformations could be saved. According to logistic regression the most important predictor of having a child with combined multiple anomalies was mother?s age, while predictor of central nervous system anomalies was gestational diabetes. The significant predictor of genetic anomalies was mother?s age. Conclusion. In our sample neurological congenital anomalies were the most common, although abnormalities of all organ systems were registered. Majority of pregnancies had to be discontinued due to combined multiple anomalies caused by genetic disorders. Older mother?s age and diabetes can imply on the increased risk for fetal malformations.

Resumen
AbstractThe variation of Polygonum viviparum L. in Europe was studied in 584 plants sampled from 14 populations at different altitudes and from different substrates in the Carpathians, Alps, Dinaric Alps, Pyrenees and Scandinavian Mts. The samples were analyzed biometrically, using 12 measured stem and inflorescence characters and 10 characters calculated from those 12. The obtained ranges of values were only slightly wider than those given in the literature. All characters significantly differed between populations and six characters were statistically significant in identifying differences between regions. Altitude, substrate and the interactions between them significantly affected the differences in characters between samples. The values of most of the measured characters were lower in samples from higher locations and on poor substrate than in those from lower localities and on rich substrate. Substrate type affected the calculated characters less but it influenced the shift between vegetative and generative reproduction. Multidimensional analyses confirmed the proximity of samples from regions either geographically close or linked via routes of postglacial migrations, despite altitude and substrate differences between them.

Resumen
The percentage of anthraquinone glycosides in the roots of Rumex crispus L. (Polygonaceae) is significantly greater than in other parts of the plant. The roots of R. crispus in different vegetation stages were investigated with regard to anthraquinone glycoside content. Their toxicity towards shrimp were also tested during the vegetation period. The data showed that the percentage of anthraquinone glycosides as well as the toxic effect on the shrimp increased during the vegetation period.
