Studies on the chemical constituents and antioxidant activities of extracts from the roots of<i>Smilax lanceaefolia</i>Roxb.

Abstract

A flavonol glycoside (1) and a steroidal saponin (2), along with beta-sitosterol and beta-sitosterol-D-glucoside, were isolated from the roots of Smilax lanceaefolia Roxb. Mineral contents were determined using the atomic absorption spectrophotometer and the total antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method.
