(Cycadaceae), is an endemic and critically endangered, tropical, dry deciduous, dioecious gymnosperm present in varied region of adjunct areas of Tirumala Hills, Seshachalam Biosphere Reserve, Southern Eastern Ghats, India. In vitro antioxidant studies by employing different parameters such as DPPH, TAC, ABTS and superoxide radical scavenging activity have been tested with different extracts viz., methanolic, ethyl acetate and n-Hexane. Screening for biochemical availability was done for flavonoids and phenolics and were evaluated statistically which showed positive correlations among biochemical availability and antioxidant activities with all the extracts. This study suggests that all the extractives showed antioxidant potency and laid a scientific proof that C. beddomei male cones are new potential source of natural antioxidants.

Northeast India has been a paradise for ethnobotanical research but the district of N.C.Hills, with its vast ethnobotanical wealth is virtually unexplored. The present study documents for the first time, the superstitious folkloric uses of plants to treat ailments among the different tribes. 16 species of plants has been identified with details on its method of use, disease, parts used, local name and growth forms. The study was conducted through informal interviews after prior informed consent. The study reflects a rich traditional knowledge base of the tribe on ethnomedicine with immense potential for a more detailed study with emphasis on its pharmacological aspects.

Dima Hasao Hill district is endowed with rich cultures of traditional system of medicine and this study is the first of its kind from the area. The aim of the study is to to assess the antimicrobial efficacy of Trema orientalis Blume (Ulmaceae) on six selected bacterial strains. The minimum inhibitory concentrations were determined with the aqueous extract to validate the application of the plant species in traditional medicine. Methods: Plant materials were collected after prior informed consent and processed using standard herbarium technique. Antimicrobial activity was determined by Kirby-Bauer Agar Disc Diffusion method with slight procedural modifications. Minimum inhibitory concentration of the aqueous extract was determined with standard antibiotics as positive control. Result: The selected bacterial strains were highly susceptible to the test material. Aqueous extracts showed fairly good activity. The zones of inhibition of all the test materials ranged from 11 to 15 mm. MIC of aqueous extract showed inhibition of bacterial growth at a concentration as low as 0.625 mg/ml. Conclusion: T. orientalis is a potentially good source of antibacterial agent. The efficacy against the selected bacterial strains and the resultant MIC values corroborates with its application in traditional medicine.
