4. Research Summary 

A. Current Research:

  • Ethno-pharmacological survey and documentation of Sikkim Traditional/Folklore Heath Care Practices: The 1st phase cross cultural Ethnopharmacological survey on Traditional/ Folklore Heath Care Practices has also been completed in East, South and West Sikkim districts of Sikkim state, India. During the survey all together fourteen traditional practitioners in three districts, which belong to six different ethnic communities were interviewed. The record of traditional knowledge on 53 different formulations used for 24 different ailments was enacted from this survey. One hundred and fifty-six different plant products, 7 animal products and 6 different organic/inorganic matters were found to be used as component of formulations.

  • Pharmacological and toxicological evaluation of Manipur & Sikkim Traditional Medicine (MTM) used for treatment of joint pain with an aim to develop commercially viable anti-arthritic products: The pharmacological evaluation of modified and optimized MTM formulations including IBSD’s Anti-arthritic formulations was investigated in details for their effectiveness using Complete Freund’s adjuvant (CFA) induced arthritis in rats to justify traditional claim. The formulations were also evaluated for phyto-chemical contents (GCMS) to identified active constituents responsible for anti-arthritic effect. In continuation of research on anti-inflammatory agents, the components for anti-arthritic formulation (IBSD/PC/AAF/1-Bater-Hidak) extracted and optimized from local bioresoources of Sikkim. The anti-arthritic formula ‘Bater-Hidak’ has been reformulated in nine different combinations and dose levels (AAF-1 to AAF-9). Out of those nine, four formulations (AAF-1, AAF-2, AAF-8 and AAF-9) and one base component (CTO) have been studied for in-vivo anti-arthritic activity using 'Complete Freund's Adjuvant' induced arthritis model on rats. Further, those selected formulation were analyses for phytochemical contains using GCMS and a ‘Phyto-Pharmacological relationship’ has been established from pharmacological and phytochemical evaluation outcomes.

  • Evaluation of Manipur & Sikkim Traditional Medicine for Anti-diabetic property with special reference to the ?-Glucosidase, ?-amylase inhibition and Glucose-6-phosphatase Activity (Metabolic Disorders): After having generated a large database, our initial focus was for pharmacological evaluation of selected bioresources for their effectiveness against diabetes as claimed by the local healers. Accordingly, the hydro alcoholic extract (HA-Tn) of Tupistra nutans (Nakima) inflorescences (IBSD-SC/EPS/IP/2016/12; Acc. No. 0298) were evaluated for in-vivo anti-diabetic potential by using STZ induced model in rats. The in-vitro ?-Glucosidase inhibition assay were also carried out and ?-amylase inhibition as well as Glucose-6-phosphatase Activity assays are under investigation to establish the mechanism of action of sample.
