The history of herbal medicines is as old as civilization. For this purpose of ascertaining the phytochemical constituents, the present work was performed into the phytochemical investigation of the plant Avicenna alba. Separation and isolation of the constituents of interest, characterization of isolated compounds and investigation of the biosynthetic pathways of the particular pathway and quantitative evaluation. Another reason for choosing this plant is the availability of the plant. Avicenna alba is the important plant used from the past. It was reported to show antimicrobial activity in literature survey. So now, the time has come to perform a proper phytochemical investigation to find its proper way into medicine. Our plan of work is to identify and isolate the chemical constituents of the aerial part of Avicennia alba and to evaluate its pharmacological action. With the above aim, this experimental work was...

In the recent years, the use of herbal products has been increasing in developing countries. Psidium guajava Linn. (Guava) family Myrtaceae is an important dietary plant used traditionally for medicinal purpose around the world. The fruit part of the guava is used because of its food and nutritional value but other part of the guava plant are used in the traditional system due to their medicinal properties. Since each part of the guava tree possess the economic value. The pharmacological and medicinal use have demonstrated the ability of this plant to exhibit antioxidant, hepatoprotective, antiallergic, antimicrobial, anticancer, cardioprotective, antidiabetic, ant cough, antidote properties. This review delineate with intervention of Psidium guajava in the management of various...

This article reviews, connected the gap between the folkloric use of Solanum nigrum and the results of evidence based experiments. Although Solanum nigrum is a rich source of one of plants most dreaded toxins solanine, it has appreciably monstrated its potential as a reservoir of antioxidants having hepatoprotective, anti-tumor, cytostatic, anti-convulsant, anti-ulcerogenic and anti-inflammatory.effects. The review encompasses in-vitro, in vivo and clinical studies done on Solanum nigrum, while examining.whether or not correct scientific measures have been taken in generating experimental evidences for its traditional uses. This review would afford research scientist to know how much is known and what is left undone in the investigation of Solanum nigrum. The compounds considered in this revieware flavonoids and other phenolics, alkaloids (especially indole terpenoid and purine alkaloids), essential oils and other terpenoids, cannabinoids, lucosinolates and isothiocyanates, and compounds having human hormone activity. The review concludes with a discussion of the possible evolutionary mechanisms that have led to the evolution of UV-B regulation of secondary metabolite accumulation. Many Ayurveda philosophers and healers...

All-spice (pimenta) is one of the under-utilized resources available in the tropical regions of the globe. It is a variety of sweet pepper used as a spice and its leaves are used for traditional culinary purpose. Researchers have studied the antioxidant potentials of the berries of the plant, but no documented work is reported on its stem, leaf and roots for antimicrobial properties. Thus, the present investigation was carried out to access the antimicrobial and anti-oxidation potentials of leaf extracts using three solvent systems, (Aqueous, acetone and methanol). All solvent systems at different concentrations were evaluated for antibacterial, antifungal and reducing capacity against selected bacterial and fungal pathogens; zone of inhibition was exhibited by methanol leaf extracts in decreasing order for Escherichia coli, Bacillus cereus, Salmonella typhimurium, and Staphylococcus aureus. Lesser inhibitory zones were obtained by acetone leaf extracts, whereas, Klebsiella pneumonia and Pseudomonas aeruginosa were not inhibited by any extracts. Aqueous extract demonstrated no inhibitory activity against tested bacterial pathogens. All the three leaf extracts were found to...

The present study of seventy one endophytic fungi isolated from Avicennia marina, Suaeda monica and Rhizophora mucronata plant leaf. Among 34 genera and 71 species was identified by Lactophenol cotton blue mounting techniques. To induce the biosynthesis of silver nanoparticles (AgNO3) using Aspergillus conicus, Penicillium janthinellum and Phomosis sp. And evaluate their antimicrobial potential. The characterization of silver nano particles on these fungi by FT-IR, UV, and Fre-SEM analysis to confirm the reduction and it is believed that protein might have played an important role in the stabilization of silver nanoparticles. The synthesized AgNO3 were found to be extracellular polydispersed spherical or hexagonal particles ranging from 6-12mm, 8-14mm 10-16mm in size. Antibacterial activity was performed using a Agar well diffusion method against Bacillus subtillus, E-coli, Enterobacter aurogens, Enterococcus, Klebseilla Pneumonia, Micrococus lutes, Salmonella typhi, Staphylococus aureus Streptococcus sp. Vibrio cholera. AgNO3 can be mycosynthesized extracelluraly using A.Conicus, Penicillium janthinellum and Phomosis sp. As the fungal system. Which is highly advantageous over chemical synthesis not only because in can be...
