Chromatographic finger print analysis of steroids in Aerva lanata L by HPTLC technique

Objective

To determine the chemical profile and steroids composition of the medicinally important plant Aerva lanata (A. lanata) L.

Methods

Preliminary phytochemical screening was done by the method as Harborne described. HPTLC studies were carried out as Harborne and Wagner et al described. The Ethyl acetate-ethanol-water (8: 2: 1.2) was employed as mobile phase for glycosides.

Results

The desired aim was achieved using Chloroform-acetone (8: 2) as the mobile phase. The methanolic extract of stem, leaves, root, flower and seeds of A. lanata showed the presence of 30 different types of steroids with 30 different Rf values from 0.04 to 0.97. 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.
