Maximum number(11) of steroids has been observed in leaves followed by root(10).Conclusions: HPTLC profile of steroids has been chosen here to reveal the diversity existing in A.lanata.Such finger printing is useful in differentiating the species from the adulterant and act as biochemical markers for this medicinally important plant in the pharma industry and plant systematic studies.展开更多
