Objective To study chemical constituents from the flowers of Chrysanthemum indicum. Methods The chemical constituents of C. indicum were isolated and purified by various chromatographic techniques, including thin-layer chromatography, silica gel, ODS reversed-phase silica gel, and Sephadex LH-20 for column chromatography, and their structures were identified by NMR spectral analysis. Results Fourteen compounds were isolated and identified as stigmata-4-ene-3-one (1), calenduladiol-3β-O-palmitate (2), 16β,22α-dihydroxypseudotaraxasterol-3β-O-palmitate (3), α-amyrin (4), urs-12-ene-3β,16β-diol (5), 3β-hydroxyurs-12-ene-11-one (6), arnidiol (7), maniladiol (8), 3β-hydroxyolean-12-ene-11-one (9), luteolin (10), apigenin (11), apigenin-7,4'-dimethyl ether (12), genkwanin (13), and 1-linoleic acid glycerate (14). Conclusion Compounds 1-6, 10-12, and 14 are isolated from the flowers of C. indicum for the first time.
