To study the chemical constituents from flowers of Gardenia jasminoides.
The compounds were isolated and purified by column chromatography and their structures were elucidated through spectroscopic techniques (NMR) and physicochemical properties.
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).
Compounds 1 – 15 are isolated from flowers of G. jasminoides and compounds 5 and 6 are isolated from genus Gardenia for the first time.
