Chemical constituents from flowers of Chrysanthemum indicum / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents of the flowers of Chrysanthemum indicum.</p><p><b>METHOD</b>The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.</p><p><b>RESULT</b>Twelve compounds were isolated and identified as acacetin (1), tricin (2), 2',4'-dihydroxychalcone(3), 5-hydroxy-4',7-dimethoxyflavon(4),7hydroxyflavonone (5), isorhamnetin (6),5,6,7-trihydroxy- 3',4', 5'-trimethoxyflanon (7 ), quercetin (8) , (3 beta, 5 alpha, 6 beta, 7 beta, 14 beta)-eudesmen-3,5,6,11-tetrol (9), syringaresinol (10), liriodendrin (11), and genkwanin (12).</p><p><b>CONCLUSION</b>Compounds 3-7, 10-12 were isolated from this species for the first time, and compounds 3, 5, 7, 10, 11 were obtained from genus Chrysanthemum for the first time.</p>
