In current study, T.S of corm and its powder, histochemical tests and preliminary physicochemical investigations were done. Results showed raphids, rosette crystals of calcium oxalate, presence of lignine, starch grains etc. Preliminary physicochemical analysis revealed loss on drying (0.75%), ash value (0.6%), alcohol soluble extract (6.8%), and water soluble extract (13.3%). These observations can be considered as standard in future studies.
