Abstract– In traditional medicinal practice Ocimum gratissimum L. (Ramatulsi) is commonly known as clove-sweet basil, belonging to the family Lamiaceae. The present study deals with the exploration of different pharmacognostic parameters of the plant. The presence of different types of trichomes; oil gland; vessels; stone cells; prismatic crystals of calcium oxalate; cystoliths of calcium carbonate; cork cells, starch grains were observed in the plant powder sample. The extractive values ofleaves, stem, roots and flowers were recorded to be 6.92±0.01%, 7.86±0.01%, 8.125±0.01% and 21.3±0.01% respectively. The ash value content of Ocimum gratissimum L., viz., leaf, stem, roots and flowers were recorded to be 9.50±0.01%, 6.45±0.01%, 4.85±0.01% and 7.80±0.01% respectively. The acid insoluble ash value of different plant parts of Ocimum gratissimum L., viz., leaves, stem, roots and flowers were recorded to be 2.5±0.01%, 1.4±0.01%, 0.95±0.01% and 2.1±0.01% respectively. The fluorescence analysis showed different colours in different reagents. The significance of this study will find its place in identification, characterization and standardization of the crude drug at species level and would help in exploration of its neutraceutical properties.
