Padina Gymnospora

In recent years, the secondary metabolites are extensively investigated as a supply of healthful agents. The sample for the study constitutes Sargassum wightii and Padina gymnospora and it was collected from the Mandapam coast, Rameswaram, TamilNadu, India. Sargassum wightii is belonging to the family Sargassum wightii and Padina gymnospora belonging to the family Dictyotaceae are 2 brown seaweeds better-known for varied biological activities like bactericide, antiviral, inhibitor, opposed cancer, medicine, etc. Five totally different extracts of Sargassum wightii and Padina gymnospora were subjected to phytochemical analysis of secondary metabolites of qualitatively phytochemical screening tests of twelve different chemical compounds (alkaloids, terpenoids, steroids, tannins, saponins, flavonoids, phenols, coumarins, proteins, sugars, quinones, and glycosides). Among the solvent extracts of alga Sargassum wightii and Padina gymnospora showed the utmost presence of saponins, carbohydrates, proteins, and quinines in 3 completely different extracts (ethanol, methanol, water) except solvent and chloroform. So the present study on extractive values of methyl alcohol extract and the binary compound extract was most in each the seaweeds, however, were significantly a lot of in P. gymnopora than S. wightii. Considering their therapeutic uses, like alternative healthful plants there’s a requirement to try pharmacognostic studies of those 2 seaweeds.

Objective: This study was designed to screen the phytochemicals present in various solvents extracts of Ruta graveolens (Rue) and furthermore to investigate their antimicrobial activity.Methods: The leaves, stems and seeds of Rue were extracted using four different solvents viz. ethanolic, methanolic, chloroform, and aqueous of varying polarity. The phytochemical screening was carried out qualitatively and Gas Chromatography-Mass Spectroscopy (GC-MS) analysis was performed to identify major phytoconstituents present in the methanolic leaf extract. The antimicrobial effect of extracts was evaluated against six microbial strains namely Bacillus subtillis, Escherichia coli, Proteus vulgaris, Candida albicans, Candida tropicalis and Micrococcus luteus with disc diffusion method.Results: Phytochemical analysis revealed the presence of various secondary metabolites such as flavonoids, alkaloids, terpenoids, saponins and carotenoid. The methanolic leaf extract showed the presence of both tannin and phenolic contents in the higher amount, whereas aqueous extract displayed in the least amount. GC-MS analysis of methanolic leaf extract revealed the presence of approximately 26 phytochemical constituents. The antimicrobial assay revealed that B. subtilis showed a high zone of inhibition (20 mm) at 200 mg/ml of methanolic extract. However, E. coli and C. tropicalis did not show any zone of inhibition against each solvent extract.Conclusion: In conclusion, secondary metabolites present in the extracts have biological activities which warrant further to evaluate in vivo pharmacological studies.

Red algae of the genus Laurencia are known to biosynthesize and secrete an immense variety of secondary metabolites possessing a spectrum of biological activities against bacteria, invertebrates and mammalian cell lines. Following a rigorous cross-species screening process, herein we report the antifouling potential of 25 secondary metabolites derived from species of the genus Laurencia, as well as the thorough evaluation of the ecotoxicity of selected metabolites against non-target marine arthropods and vertebrate cell lines. A number of these secondary metabolites exhibited potent antifouling activity and performed well in all screening tests. Our results show that perforenol (9) possesses similar antifouling activity with that already described for bromosphaerol, which is used herein as a benchmark.

Euryops pectinatus ‘Viridae’ weed belonging to the family Asteraceae is commonly known as Golden Euryops or African daisy. Present investigation includes phytochemical analysis of methanol extract of Euryops pectinatus weed for the presence of various secondary metabolites. Presence of various secondary metabolites was observed including phenols, flavonoids, alkaloids, steroids, saponins, glycosides, etc. These secondary metabolites are well known for their biological activities like antioxidation, anti-cancerous, anti-microbial, cardiovascular, and anti-aging. After determination of rich secondary metabolites in the methanol extract, mass spectrometric analysis was carried out for the identification of compounds present in Euryops pectinatus. Eight compounds were identified in the methanol extract reported for nematicide, antioxidant, analgesic, antitumor, anticancerous and several other important activities. Thus phytochemical and mass spectrometric analysis would open new doors to natural product research that would be cost effective and safe for the mankind.

Survey have proven the popular Canellaceae family use to treat various diseases such as: muscular pains, infections, stomatitis, anti-malaric, healing, among others. The main use of these species is in the extracts form and essential oils extracted from the leaves and stem. Highlighting the importance of this family on the pharmacological point of view and the fact that few studies in the literature have reported the characterization of the essential oils compounds and their respective biological activities. The objective of this study was to carry out a systematic review of previous studies on essential oils of the Canellaceae family species and their biological activities. The databases Scopus, Web of Science and PubMed were used for the search and a bibliographical manager was used. A total of 143 files were analyzed, of which 21 presented the phytochemical analysis and / or essential oils biological activities of these species. Few species have been studied so far, such as Canella winterana, Cinnamosma fragans, Cinnamosma madagascariensis, Cinnamodendron dinisii. It can be observed that the major constituents for these species essential oils were: 1,8-cineol, linalool, limonene, alpha and beta-pinene. And that the main proven activities were: antibiotic, antifungal, insecticide, larvicide, trypanocidal, cytotoxic, molluscicide, immunomodulatory, anti-inflammatory and anticonvulcionate. From this literature review, it was possible to identify species that have not yet started studies and possible activities of their essential oils, mainly due to the almost homogeneous presence of the major constituents, making possible new research as well as projects and programs.

Anti Tumor Activity

The polysaccharides in many plants are attracting worldwide attention because of their biological activities and medical properties, such as anti-viral, anti-oxidative, antichronic inflammation, anti-hypertensive, immunomodulation, and neuron-protective effects, as well as anti-tumor activity. Denodrobium species, a genus of the family orchidaceae, have been used as herbal medicines for hundreds of years in China due to their pharmacological effects. These effects include nourishing the Yin, supplementing the stomach, increasing body fluids, and clearing heat. Recently, numerous researchers have investigated possible active compounds in Denodrobium species, such as lectins, phenanthrenes, alkaloids, trigonopol A, and polysaccharides. Unlike those of other plants, the biological effects of polysaccharides in Dendrobium are a novel research field. In this review, we focus on these novel findings to give readers an overall picture of the intriguing therapeutic potential of polysaccharides in Dendrobium, especially those of the four commonly-used Denodrobium species: D. huoshanense, D. offininale, D. nobile, and D. chrysotoxum.
