Abstract: Isolation of
triterpenoid and antioxidant activity from leaf of Sonchus arvensis extracts
have been done. The methods used for isolation were maseration, fractionation
and column chromatography. The isolated compound is white solid with melting
point at 123.4-124.8oC which gave single spot in every eluent. The
functional groups of the compound were
conjugated double bond, -OH alcohol, C-O alcohol, C-O ether, C-H and specific
absorption for triterpenoid was geminal dimethyl. Furthermore, determination of
antioxidant activity of the isolated compound was analyzed by DPPH radical
scavenging method and have showed that its activities in methanol, ethyl
acetate and hexane were found to be 75.8; 79.5; and 43.1 %, respectively.
