Abstract:
OBJECTIVETo study the chemical constituents from Centipeda minima.
METHODThe compounds were separated and purified by silica gel, reserved phase silica gel and Sephadex LH-20 gel column chromatography. Their structures were identified on the basis physicochemical property and spectral analysis.
RESULTFour chemical constituents were separated from ethyl acetate extracts and five chemical constituents were separated from n-butanol extracts of C. minima and identified as (2R,3R)-(+)-7,4'-di-O-methyldihydrokaempferol (1), iristectorin A (2), 4',5,8-trihydroxy-7-methoxyisoflavone (3), 3-trimethoxyquercetin (4), 3-O-caffeoyl-alpha-glueopyranose (5), 3-O-caffeoyl-beta-glucopyranose (6), quercetin (7), epipinoresinol (8) and hispidulin (9).
CONCLUSIONCompounds 1-3, 5-6, 8 and 9 are separated from this genus for the first time.
