Symphonia globulifera L.f. (Anani) is an arboreal species, which occurs in the Amazon with antimalarial and antimicrobial properties, especially in the treatment of skin inflammations. It is also used as a general tonic and laxative for pregnant women and its sap/latex is used against rheumatism and tumors. The utilization of natural products from plant origin implies in pharmacobotanical quality control, which consist of the technical specifications of the species. Anatomical description of the leaves and petioles of Symphonia globulifera L. f. were performed. Epidermal cells on both sides of the leaves were observed; they are heterodimensional and polygonal. The stomata are anomocytic and were found only on the abaxial surface. The petiole is plan-convex coated with quadrangular cells and thick cutinization. The results are relevant to the anatomical characterization of the species since data on leaf anatomy of S. globulifera are...

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...

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...
