The ethanolic extract showed highest amongst them followed by hydroalcoholic, ethyl acetate and methanolic extract respectively as compared to standard BHT. The HPTLC analysis revealed several bands with different R, values. The scanning of plates was done for determining metabolites such as flavanoids, polyphenolics etc. The flash separation of the AsEt extract yielded total 11 fractions. As per the R, values of bands observed, the fractions from AsEt 7-11 did not show any bands and total six fractions of AsEt namely AsEt 1,2,3, 4, 5, 6 were selected for further analysis. inhibition.
