TK Validation on Medicinal Plants

The research partnership establishedbetween MSSRF and CSIR-NIIST, Thiruvananthapuramsince 2014 has resulted in publication of four papers inhigh impact journals. The evidences are in validation of some of the claims on the efficacy and medicinal benefits of the plant species known to the tribal community of Wayanad district. The papers are on (i) isolation, characterization and anti-inflammatory activity of the compounds isolated from the stem bark of H. parviflora; (ii) isolation and characterization of resveratrol oligomers from the stem bark of Hopea ponga; (iii) Dihydro-β-agarofuransesquiterpenoids from the seeds of Celastrus paniculatus, and (iv) Comparison of antidiabetic potential of (+) and (−)-hopeaphenol, a pair of  enantiomers isolated from Ampelocissus indica (L.) and Vateria indica Linn., with respect to inhibition of digestive enzymes and induction of glucose uptake in L6 myotubes. Read these papers in following Links:

Study by Ratheesh and Anil Kumar (unpublished) in the district among the different ethnic groups have revealed there are 434 flowering plants used by the tribal people of Wayanad of which 184 are of food use, 244 are of medicinal use, 7 species are used for extracting fibres and 68 plants are recorded for other uses like fish poisoning, magico-religious, canes, resins and as other Minor Forest Produces. The MoU between MSSRF and CSIR-NIIST is being renewed and research will be continued on the priority species listed in the report of Ratheesh and Anil Kumar (2012).
