Abstract

OBJECTIVE:

To study the chemical constituent bud of the flowers of Jasminum officinale var. grandiflorum.

METHOD:

The compounds were isolated and purified by recrystallization and chromatography on silica gel and Sephadex LH - 20 column. Their structures were elucidated on the basis of physicochemical properties and spectral analysis.

RESULT:

Six triterpenoid saponins were identified as 3-O-alpha-L-rhamnopyranosyl (1 --> 2)-beta-D-xylopyranosyl- hederagenin-28-O-beta-D-galactopyranosyl (1 --> 6)-beta-D-galactopyranosyl ester (1), hederagenin-3-O-beta-D-glucopyranosyl (1 --> 3)-alpha-L-arabinopyranoside (2), 2alpha, 3beta, 23-trihydroxyolean-12-en-28-oic-O-beta-D-glucopyranosyl ester (3), hederagenin-3-O-beta-D-xylopyranosyl (1 --> 3)-alpha-L-rhamnopyranosyl (1 --> 2)-alpha-L-arabinopyranoside (4), 2alpha, 3beta, 23-trihydroxyolean-12-en-28-oic-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranosyl ester (5), hederagenin-3-O-alpha-L-rhamnopyranosyl (1 --> 2)-alpha-L-arabinopyranoside (6).

CONCLUSION:

Compound 1 is a new compound. Compounds 2, 3, 4, 5, 6 were isolated from the genus Jasminum for the first time.
