[Chemical constituents from seeds of Brassica campestris]
Abstract:
Fourteen compounds were isolated by column chromatography from the ethyl acetate extract of the seeds of Brassica campestris. Their structures were elucidated by physicochemical properties and spectroscopic data analysis. The isolated compounds were respectively identified as (5Z,7E)-4, 4-dimethyl-5-acetyl-5, 7-nonadienoic acid (1), indole-3-carboxaldehyde (2), blumenol A (3), vinylsyringol (4), sinapinic acid (5), sinapic acid ethyl ester (6), protocatechuic acid (7), crinosterol (8), campesterol (9), 7-oxo-stigmasterol (10), kaempferol (11), 2,5-dihydroxybenzoic acid (12), syringic acid (13) and daucosterol (14). Compound 1 was a new compound and the other compounds were isolated from this plant for the first time except for compounds 4, 5 and 13.
