Results: Macroscopic and Microscopic study showed distinct characteristics in the leaves of Kamala like Anomocytic type of stomata, Collenchymatous hypodermis, Vascular bundle covered with bundle sheath etc. Powder analysis revealed the presence of Rosette crystals of Calcium oxalate, few spherical to oval shaped starch grains etc. HPTLC Densitometric scan at 254nm shows 7spots with R_f 0.03 (has maximum area of 36.46%), at 366nm densitometric scan shows 8 spots with Rf 0.55 (which had maximum area 24.56%). Conclusion: Pharmacognostic study of leaves is helpful in sample identification and to ensure quality and purity standards.
