Results: Organoleptic characters, macro – microscopy, physico-chemical studies viz. total ash, water soluble ash, acid insoluble ash, water, alcohol and hydro – alcohol soluble extractive, loss on drying at 105°C, pH successive extractive values by Soxhlet extraction method and HPTLC and 1H NMR were recorded.
