Triterpenoids from canes with leaves of Trachelospermum jasminoides / 中草药

ABSTRACT

Objective To study the triterpenoids from the canes with leaves of Trachelospermum jasminoides.Methods The compounds were separated and purified by column chromatography with silica gel,RP-C_(18),Sephadex LH-20 and identified by IR,MS,NMR,and 2D-NMR.Results Eight triterpenoids were identified as trachelosperoside F(Ⅰ),trachelosperoside B-1(Ⅱ),trachelosperoside D-1(Ⅲ),trachelosperoside E-1(Ⅳ),3?-O-D-glucopyranoside quinovic acid(Ⅴ),3?-O-?-D-glucopyranoisde quinovic acid 27-O-?-D-glucopyranosyl ester(Ⅵ),3?-O-?-D-glucopyranoside cincholic acid 27-O-?-D-glucopyranosyl ester(Ⅶ),trachelosperogenin B(Ⅷ),respectively.Conclusion Compound Ⅰ is a new compound and compounds Ⅱ-Ⅷ are isolated from this plant for the first time.
