ABSTRACT

Three known triterpenoids,  taraxer-14-ene-3-one (1), taraxer-14-ene-3α-ol (2), taraxer-14-ene-3β-ol (3) and one known acylated steroid glucoside, stigmast-5-en-3β-yl (6’-O-heptadecanoyl-β-D-glucopyranoside) (4) were isolated from the n-hexane fraction of methanol extract of the leavesof Excoecaria agallocha L. collected in the Thai Binh province,Vietnam. Their structures were elucidated on the basis of spectroscopic data and by comparison with their spectral data reported in literature. This is the first isolation of compound 4 from this species.

Key words: Excoecaria agallocha L.; triterpenoid; taraxer-14-ene-3-one; taraxer-14-ene-3α-ol; taraxer-14-ene-3β-ol; acylated steroid glucoside; stigmast-5-en-3β-yl (6’-O-heptadecanoyl-β-D-glucopyranoside); methanol; n-hexane fraction
