Resumen
The present experiment was designed to investigate the pesticididal property of the chosen ferns viz., Cyclosorus interruptus (Willd.) H.Itô (Theylepteridaceae), Christella dentata (Willd.) (Forssk.) Brownsey et Jermy (Theylepteridaceae), and Nephrolepis cordifolia (L.) Presl. Phytochemical analysis carried out using methanol extracts of the experimental ferns revealed the presence of the secondary metabolites like alkaloids, steroids, tannins, flavonoids, cardiac glycosides and phenolic compounds in methanolic extracts of the experimental ferns. The nano particles of chosen fern extracts synthesized using silver nitrate (AgNO3) showed the characteristic colour change from pale yellow to dark brown indicated the synthesis of silver based nano particles. The UV- Visible spectrum obtained for the silver nanoparticles (AgNPs) of the experimental ferns confirmed the synthesis of nanoparticles (433.50 nm, 447.00 nm and 444.00 nm for C. interruptus, C. dentata and N. cordifolia, respectively). Bioassay on the pesticidal property of the methanol extracts and ferns-AgNP were evaluated against third instar larvae of Spodoptera litura (Fab.) (Lepidoptera: Noctuidae). The results of the bioassay revealed the impact of methanolic extracts and their AgNP particles on the developmental period, pupal weight, percentage of pupation and adult emergence and also caused larval, pupal and adult deformities that confirm the insecticidal activity of the experimental ferns.

Resumen
Endophytic bacteria have been known to produce high levels of secondary metabolites. The sterile leaves of the sea fern (Acrostichum aureum L.) contain many phytochemical compounds. This sea fern is often found in peat swamp areas. The aim of this study was to isolate, partial characterization, and analysis of bioactive compounds from endophytic bacteria of sea ferns to determine their bioactive compounds. Endophytic bacteria were isolated by a direct technique using nutrient agar (NA) media. In this study, the endophytic bacteria were characterized by macroscopic, microscopic, and Gram. Several tests were further performed, namely phytochemical test and Fourier Transform Infra Red (FT IR) FTIR tests from a crude extract of secondary metabolites of bacteria. The results of the isolation obtained six isolates of endophytic bacteria consisting of all isolates were Gram-negative. The phytochemical test results for the six isolates were positive for alkaloids and saponins but no steroids. Based on the results of phytochemical tests and FT IR, it is suspected that the isolate DSB 1.6 has similarities with the alkaloid functional group. This endophytic bacterial isolate can be developed as a candidate for produced of pharmacological compounds.

Resumen
ABSTRACT:The aim of the present study was to evaluate the therapeutic properties of selected fern, Chelianthusalbomarginataand to identify its functional compounds. The methanolic fern-extract (MFE) of these ferns was assessed for anti-bacterial activities by measuring inhibition zones against a panel of pathogenic bacterial strains using agar diffusion method. MFE at a concentration of 25 μg/ml showed marked anti-bacterial activity against all bacterial strains (6-23mm zone of inhibition) and was maximum against Enterobacter sp (23 mm). In addition, the MFE of C. albomarginatahad the best MIC values of 2.25µg/ml against S. aureus and Enterobacter sp., respectively. The MFE also possessed good anti-lipolytic activity (66.5%) against a porcine pancreatic lipase (PPL) and cholesterol oxidase inhibition (79%). This result showed that MFE of C. albomarginataunder optimal concentrationis not only a potent source of natural anti-oxidants and anti-bacterial activity but also possesses efficient cholesterol degradation and anti-lipolytic activities, that is to be beneficial in the body weight management.

Resumen
The preliminary phytochemical analysis of ferns viz., Cyclosorus interruptus (Willd.) H.Itô (Theylepteridaceae), Christella dentata (Willd.) (Forssk.) Brownsey et Jermy (Theylepteridaceae), and Nephrolepis cordifolia (L.) Presl revealed the presence of the secondary metabolites like alkaloids, steroids, tannins, flavonoids, terpenoids, cardiac glycosides, phenolic compounds and terpenoids in crude extract. The characteristic colour change and the UV- Vis spectrum obtained for the silver nanoparticles (AgNPs) formulation of the experimental ferns confirmed the synthesis of nanoparticles (433.50nm, 450.00nm and 444.00 nm for C. interruptus, C. dentata and N. cordifolia, respectively). The pesticidal property of the crude extracts and ferns-AgNP (Fe-AgNP) were evaluated in the laboratory on Spodoptera litura (Fab.)(Lepidoptera: Noctuidae) third instar larvae. The crude extract and Fe-AgNP formulations exerted their influence on the developmental period, pupation rate, pupal weight and adult emergence which were reduced significantly. They also caused larval, pupal and adult deformities that confirm the insecticidal activity of the plant.

Resumen
Fern is cosmopolitan plants which are almost scattered in all parts of the world, one of which is found in Baluran National Park and in Malang. The potential and benefits of these ferns are quite important for agriculture and medicine because of the chemical compounds they have, especially in Pteris vitatta L. This study aimed to analyze secondary metabolites contained in P. vittata L. in Baluran National Park, Situbondo and in Malang. The samples used were leaves and rhizome P. vittata extracted using methanol 96%, followed by a qualitative test of the content of alkaloids, flavonoids, terpenoids, polyphenols, tannins, saponins, using phytochemical screening methods with several reagents. The results showed that the leaves and Rhizome P. vittata L.. in Baluran National Park, Situbondo were positively containing secondary metabolites of terpenoids, polyphenols, tannins, saponins, and alkaloids (Dragendorf and Bouchardat reagents), whereas flavonoids were not present in all samples. However, the results of P. vitatta L. phytochemical screening around Malang State University positively contained flavonoids, polyphenols, terpenoids, alkaloids (Wagner and Dragendorf reagents). The difference in results from these two places is because the secondary metabolite content in plants is affected by stressful environmental conditions such as soil texture where it is grown or is affected by the precursors of the secondary metabolites of the metabolites.

Resumen
The genus Blechnum represents one of the most ecologically and therapeutically important groups of ferns that grow in tropical, subtropical and temperate regions. In this work, the chemical fingerprint of lyophilized extracts of Blechnum chilense, B. hastatum, B. magellanicum and B. penna-marina species, the determination of their antioxidant activity through ORAC, FRAP and DPPH assays and inhibition of cholinesterase enzymes (AChE and BChE), and an in silico analysis of selected majority compounds on cholinesterase enzymes were identified. Nineteen compounds were recorded for B. chilense, nine in B. hastatum, seventeen in B. magellanicum and seventeen in B. penna-marina by liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS). The content of phenolic compounds, flavonoids, antioxidant activity and enzyme inhibition were variable among species, with best results for B. penna-marina. Molecular docking evidenced low toxicities, significant pharmacokinetic properties, and significant binding affinities of the tested compounds for the AChE and BChE enzymes. These fern species show high diversity of bioactive compounds and represent a promising resource in phytotherapy, especially for their optimal levels of phenolic compounds that support their antioxidant activity.

Resumen
There is a search for plant based alternatives to synthetic chemicals to control pests in crop plants were started from any years back. In this study, the efficacy of common ferns to control the whitefly, Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) in coconut plantation was investigated. The whiteflies are prevalent throughout the year in the coconut fields and cause severe losses to the farmers. Ferns such as Adiantum caudatum, Hemionitis opposita, Pteris biaurita, Thelypteris meeboldii and Nephrolepis cordifoliawere evaluated for their efficacy in the control of the whitefly, A. rugioperculatus. The aqueous extracts of the ferns were screened at different concentrations viz., 1.0, 2.0, 3.0, 4.0 and 5.0% against A. rugioperculatus under laboratory conditions. Extracts from H. opposita and Thelypteris meeboldii showed the maximum mortality rate of 87% followed by Nephrolepis cordifolia (86%), Adiantum caudatum (83%) and Pteris biaurita (77%) at 5% concentration after 96 hours of treatment. The phytochemical screening of the extracts showed a qualitatively increased level of saponins in H. opposita and T. meeboldii. Reduced chlorophyll, carbohydrate and amino acid content were observed in the whitefly's infested leaves and increased protein content was observed in the infested leaves. Based on the study, the aqueous extracts of H. opposita and T. meeboldii can be recommended for the whitefly control in coconut plantations

Resumen
The genus Diplazium (family: Athyriaceae) comprises approximately 350 species of pteridophytes. Diplazium esculentum (Retz.) Sw. is an important member of this genus and commonly known as a wild vegetable in the Himalayan and sub-Himalayan communities. According to the literature analysis, D. esculentum was traditionally used for the prevention or treatment of several diseases such as diabetes, smallpox, asthma, diarrhea, rheumatism, dysentery, headache, fever, wounds, pain, measles, hypertension, constipation, oligospermia, bone fracture, and glandular swellings. Various extracts of D. esculentum were evaluated to elucidate their phytochemical and pharmacological activities. A wide array of pharmacological properties such as antioxidant, antimicrobial, antidiabetic, immunomodulatory, CNS stimulant, and antianaphylactic activities have been recognized in different parts of D. esculentum. The review covers a systematic examination of pharmacognosy, phytochemistry, and pharmacological applications of D. esculentum, but scientifically, it is not fully assessed regarding complete therapeutic effects, toxicity, and safety in the human body. The published literature on D. esculentum and its therapeutic properties were collected from different search engines including Wiley online, PubMed, Springer Link, Scopus, Science Direct, Web of Science, Google Scholar, and ACS publications by using specific terms such as “Diplazium esculentum, bioactive compounds, biological activities and health benefits” from 1984 to 2021 (March). Therefore, further studies are required to identify the detailed action mechanism of D. esculentum in vitro/in vivo, and also, more studies should focus on conservation, cultivation, and sustainable utilization of the species.
