Abstract
Various traditional systems of medicine enlightened the importance of the leaves of Bixa orellana (Bixaceae) to have a great medicinal value. The present study was aimed at pharmacognostic and preliminary phytochemical evaluations of B. orellana leaves. The pharmacognostic investigations were carried out in terms of organoleptic, microscopic and physical parameters. The dried leaves were subjected to successive Soxhlet extraction using petroleum ether, chloroform, ethyl acetate, methanol and water. These solvent extracts were subjected to a preliminary phytochemical screening to detect the ...

Abstract
Seaweeds from Asia have a great commercial application as the source of phycocolloides since a very long time. Present investigation reveals biochemical composition of three commonly occurring seaweeds, along the central west coast of India. Seaweeds viz. Ulva fasciata (green), Sargassum ilicifolium (brown) and Gracillaria corticata (red) were analyzed for protein, lipid, carbohydrate, ash and mineral content. S. ilicifolium ranked highest in total protein content among the species analyzed. All species contained approximately 5% crude lipid, although U. fasciata species had ...

Abstract
The methanolic extract of young and mature leaves of nine coastal plants from West coast of Maharshtra were analysed to evaluate free radical scavenging activity. The antioxidant activity was evaluated using 1,1-diphenyl-2-picryl hydrazyl radical (DPPH) and the reductive potential of the methanolic extract. The highest antioxidant activity was recorded in young leaves of Hibiscus tiliaceus (76 %), followed by Syzigium corymbosa (71 %) Calophyllum inophyllum (68 %) and Colubrina asiatica (55 %). The plant species also posseses appreciable reductive potential. The ...

Abstract
A total of 19 species of weeds in wheat fields representing 11 families were collected from the different region of Mahendergarh district of Haryana during the winter seasons of November 2007 to April 2008 and November 2008 to April 2009. The survey revealed that a significant number of weed species has an ethnomedicinal value, besides this some weeds are highly nutritious and their leaves may be used as food or herbal medicine. The study suggested that there is a tremendous scope ...

Abstract
The antioxidant activity of the methanolic and aqueous extracts of Martynia annua Linn. leaves were evaluated by several in vitro systems of assay, namely, reducing power assay, DPPH radical-scavenging activity, nitric oxide scavenging activity, H2O2 radical scavenging activity, superoxide radical scavenging assay, hydroxyl radical-scavenging activity, and total antioxidant capacity. Total phenolic content was measured by Folin–Ciocalteau reagent. The antioxidant property depends upon concentration and increased with increasing amount of the extract. The free radical scavenging and antioxidant activities may be attributed ...

Abstract
Aegle marmelos Linn. (Rutaceae) is reported to possess a number of medicinal properties including antidiarrhoeal, antimicrobial, antifungal and activities. The antiaflatoxigenic effects of ethanolic extract of the leaves of Aegle marmelos were studied on common aflatoxigenic fungal species. Aegle marmelos exhibited antifungal and antiaflatoxigenic activity at a concentration range of 0.5 to 2 mg/ml. The shake flask method was used to evaluate the antifungal and antiaflatoxigenic activity. The extract showed varied levels of antifungal and antiaflatoxigenic activity against the test fungi. ...

Abstract
Extracts from a total of 37 medicinal plants from 15 families were screened for their phenolic compounds and antioxidant activities. Phenolic compounds identified were gallic, vanillic, syringic, caffeic, 2,5-dihydroxybenzoic, rosmarinic and p-coumaric acids. Gallic acid varied from 0.00 – 3.14 g/L, vanillic acid varied from 0.00 – 1.32 g/L, syringic acid varied from 0.00 – 3.40 g/L, caffeic acid varied from 0.00 – 2.04 g/L, 2,5-dihydroxybenzoic acid varied 0.00 – 2.64 g/L, rosmarinic acid varied from 0.00 – 1.90 g/L and ...

Abstract
The Present study deals with the detailed pharmacognostical evaluation of Argyreia speciosa (Burm.f.) Bojer. (Convolvulaceae). Morphoanatomy of the root part have been studied with the aim to aid pharmacognostic and taxonomic species identification. The physicochemical, morphological and histological parameters presented in this paper may be proposed as parameters to establish the authenticity of A. speciosa and can possibly help to differentiate the drug from its other species. ...

Abstract
The aim of the present study was to investigate the different plant sources of Shankhpushpi viz., Evolvulus alsinoides Linn. (EA), Convulvulus pluricaulis Choisy. (CP), Canscora decussata Schult. (CD) and Clitorea ternatea Linn. (CT) for their identification utilizing the technique of thin layer chromatography (TLC). Shankhpushpi is vigorously advertised for its effects on learning and memory in print and electronic media in India. Various phytoconstituents have been reported in these herbs namely, p-coumaryl derivatives, xanthones, anthocyanins and flavonones. We explored the two ...
