Perfact Enviro Solutions Pvt. Ltd. 3.10 ECOLOGY & BIODIVERSITY 3.10.1 Gaura Graphite Mine (4.664 ha.)by Sri Shishir Kumar Poddar 3.10 ECOLOGY & BIODIVERSITY 3.10.1 Introduction on Ecology and Biodiversity A natural ecosystem is a structural and functional unit of nature. It has different components, which are interrelated to each other survive by interdependence. An ecosystem has self-sustaining ability and controls the number of organisms at any level by cybernetic rules. The basic purpose to explore the biological environment under Environmental Impact Assessment (EIA) is to assist the decision making process and to ensure that the project options under consideration are environmental-friendly. An ecological survey of the study area was conducted, particularly with reference to listing of species and assessment of the existing baseline ecological conditions in the study area. The main objective of the ecological survey is aimed at assessing the existing flora and fauna components in the study area. Data has been collected through extensive survey of the area with reference to flora and fauna. With the change in environmental conditions, the vegetation cover as well as animals reflects several changes in its structure, density and composition. The present study was carried out in separately for floral and faunal community of core and buffer zone respectively. 3.10.2 Need to study The present study was undertaken with the following objectives: To assess the nature and distribution of vegetation in core and Buffer Zone. To assess the animal life spectra (within 5 km radii) To achieve the above objectives a study area was undertaken. The different methods adopted were as follows: Compilation of secondary data with respect to the study area from published literature and various government agencies; Generation of primary data by undertaking systematic ecological studies in the area. 3.10.3 Selection of Sampling Location for the study of Flora and Fauna Core Zone: Core zone is the area where mining is to be done. Core zone comprises of 4.547 Ha. Government barren land and 0.117 ha. private land. In the private land Prepared by Page 89 Perfact Enviro Solutions Pvt. Ltd.

    Distribution of flavonoids among Malvaceae family members – A review Vellingiri Vadivel, Sridharan Sriram, Pemaiah Brindha Centre for Advanced Research in Indian System of Medicine (CARISM), SASTRA University, Thanjavur, Tamil Nadu, India Abstract Since ancient times, Malvaceae family plant members are distributed worldwide and have been used as a folk remedy for the treatment of skin diseases, as an antifertility agent, antiseptic, and carminative. Some compounds isolated from Malvaceae members such as flavonoids, phenolic acids, and polysaccharides are considered responsible for these activities. Although the flavonoid profiles of several Malvaceae family members are REVIEW REVIEW ARTICLE investigated, the information is scattered. To understand the chemical variability and chemotaxonomic relationship among Malvaceae family members summation of their phytochemical nature is essential. Hence, this review aims to summarize the distribution of flavonoids in species of genera namely Abelmoschus, Abroma, Abutilon, Bombax, Duboscia, Gossypium, Hibiscus, Helicteres, Herissantia, Kitaibelia, Lavatera, Malva, Pavonia, Sida, Theobroma, and Thespesia, Urena, In general, flavonols are represented by glycosides of quercetin, kaempferol, myricetin, herbacetin, gossypetin, and hibiscetin. However, flavonols and flavones with additional OH groups at the C-8 A ring and/or the C-5′ B ring positions are characteristic of this family, demonstrating chemotaxonomic significance. Key words: Flavones, flavonoids, flavonols, glycosides, Malvaceae, phytochemicals INTRODUCTION connate at least at their bases, but often forming a tube around the pistils. The pistils are composed of two to many connate he Malvaceae is a family of flowering carpels.

ABSTRACT Helicteres isora linn, an ayurvedic herb, is distributed widely in forest throughout India. Almost its all parts are used traditionally. The fruits are useful in diarrhoea, dysentery, wounds, ulcers, hemorrhages and diabetes. The fruit after collection, authentication and drying, was extracted with petroleum ether, chloroform, methanol and water using soxhlet extractor.The present study was aimed to isolate the constituents and evaluate the antimicrobial properties of isolated constituents of methanolic extract of fruits of Helicteres isora linn. Isolation of alkaloids, flavonoids and phenolic compounds was done by using HPTLC technique. The invitro antimicrobial activities of methanolic extract, isolated alkaloids, flavonoids and phenolic compounds were investigated against Escherichia coli, Pseudomonas aeruginosa, Salmonella abony and Staphylococcus aureus by cup-plate diffusion method.The methanolic extract showed activity against Escherichia coli, Pseudomonas aeruginosa, Salmonella abony and Staphylococcus aureus., isolated phenolic compounds against Escherichia coli, Pseudomonas aeruginosa and Salmonella abony., isolated flavonoids against Pseudomonas aeruginosa and Staphylococcus aureus., and isolated alkaloids against Escherichia coli and Staphylococcus aureus.Minimum inhibitory concentration was determined by liquid broth method. Minimum inhibitory concentration of methanolic extract against Pseudomonas aeruginosa was found to be 10µg/ml and that against Staphylococcus aureuswas found to be 8µg/ml. Keywords: Helicteres isora linn, Sterculiaceae, Antimicrobial activity, Zone of inhibition, MIC.
