The present investigation was aimed to reveal the terpenoid profile of Clitoria ternatea Linn seed, stem and leaves using HPTLC. Preliminary phytochemical screening was carried out by Harborne method. HPTLC studies were followed by Harborne and Wagner et al. method. The n-hexane-ethyl acetate (7.2:2.9) was employed as mobile phase for terpenoids. The methanolic extracts of Clitoria ternatea stem, leaves and seeds showed the presence of 23 different types of terpenoids with 17 different Rf values with range 0.01 to 0.92. In general more degree of terpenoids diversity has been observed in vegetative parts when compared to the reproductive part (Seed). Maximum number  of terpenoids has been observed in leaves followed by seed (8). The proposed HPTLC profile can be used for the identification of the medicinally important plants and distinguish from its adulterant.
