[Chemical constituents from flowers of Gardenia jasminoides].
OBJECTIVE
To study the chemical constituents from flowers of Gardenia jasminoides.


METHODS
The compounds were isolated and purified by column chromatography and their structures were elucidated through spectroscopic techniques (NMR) and physicochemical properties.


RESULTS
15 compounds were isolated from flowers of G. jasminoides, and identified as 5, 7, 3'-trihydroxy-6, 4', 5'-trimethoxyflavone (1), 5, 7, 3', 5'- tetrahydroxy-6, 4'-dymethoxyflavone (2), kaempferol (3), quercetin (4), 3beta,23- dihydroxyurs-12-en-28-oic acid (5), 3beta,19alpha-dihydroxy-urs-12-en-28-oic acid (6), 3beta,19alpha,23-trihydroxy-urs-12-en-28-oic acid (7), emodin (8), physcion (9), crocin-I (10), beta-daucosterol (11), beta-sitosterol (12), stearic acid (13), palmitic acid (14), oleic acid (15).


CONCLUSIONS
Compounds 1 - 15 are isolated from flowers of G. jasminoides and compounds 5 and 6 are isolated from genus Gardenia for the first time.
