Abstract:
Objective To study the chemical constituents from Achyrocline satureioides. Methods Chemical constituents from A. satureioides were separated and purified by a variety of chromatographic techniques, and their structures were identified by various spectroscopic methods. Results Twenty-one compounds were isolated from ethyl acetate fraction of the plant, which were α-amyrin (1), ergosta-4,6,8,22-tetraene-3-one (2), (R)-24-ethylcholest-4-en-3,6-dione (3), clovandiol (4), caryolane-1,9β-diol (5), lepidissipyrone (6), 5,7-dihydroxy-3,6-dimethoxyflavone (7), quercetin-7-O-β-D-glucoside (8), pinocembrin (9), (2R,3R)-taxifolin (10), quercetin-4’-O-β-D-glucoside (11), helichrysetin (12), 3-[5,7-dihydroxy-2,2-dimethyl-8-(2-(S)-methyl-butanoyl)-2H-chromen-6- yl-methyl]-6-ethyl-4-hydroxy-5-methyl-pyran-2-one (13), quercetin (14), protocatechuic acid (15), (+)-(3R)-3-hydroxyl-4,4- dimethyl-4-butyrolactone (16), (4S,5R)-5-(4’-methyl-3’-pentenyl)-4-hydroxy-5-methyldihydrofuran-2-one (17), genkwanin (18), quercetin-3-methyl ether (19), galangin (20), and neosakuranin (21). Conclusion Compounds 1, 4, 5, 16, 17, and 21 are obtained from the genus for the first time, and compounds 1-12, 16-18, and 21 are obtained from the plant for the first time.
