T wo new tri terpenoids namely, 3α - hydroxyferna-7, 9(11),22-trien-12-one (1) and 3α - acetoxyferna-7, 9(11)-dien-22-ol (2) along with two known compounds 3α,16α-dihydroxyferna-7,9(11)-dien-12-one (3) and 3α,16α-dihydroxyfern a -8-en-11-one (4) were isolated from Lonicera quinquelocularis . Their structures were elucidated by chemical and modern spectroscopic techniques. All the compounds showed good antioxidant activities in the DPPH radical scavenging assay.KEYWORDS
