Phytochemical Analyses and Activity of Herbal Medicinal Plants of North-East India for Anti-Diabetic, Anti-Cancer and Anti-Tuberculosis and their Docking Studies

The traditional knowledge of medicinal plants that are in use by the indigenous Jaintia tribes residing in few isolated pockets of North-East India is documented here. The present study was carried out through the personal discussion with the president of the Jaintia Indigenous Herbal Medicine Association, Dr.H. Carehome Pakyntein from Jowai, Meghalaya. The plants being used generation after generation by his family of herbalists to cure ailments like tuberculosis, cancer and diabetes were selected for the present study. In order to scientifically validate the use of these selected plants for the cure of selected diseases, phytochemical analyses, characterization and molecular docking studies of some of the selected compounds from these plants have been carried out. The compounds 2-hydroxy-4-methoxy-Benzaldehyde from methanolic extract of Strophanthus Wallichii and DL tetrahydropalmatine from Stephania Hernandifolia have been confirmed after determining their molecular structures, justifying the activity of these two plants against TB and cancer, respectively. The present study covers the potentials of some of the medicinal plants of North east India in curing common diseases due to which millions of people suffer and die. The presence of certain compounds in these plants related to the cure of the diseases deserves further studies.
