tricin and 3-methylquercetin

To investigate the chemical constituents of the flowers of Chrysanthemum indicum.. The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.. 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).. 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.

To study the chemical constituents in seeds of Atriplex centralasiatica.. The chemical components were isolated by solvents extractions and column chromatography. The chemical structures were identified on the basis of physicochemical constants and spectral data.. Six compounds were isolated and identified as isorhamnetin(I), tricin(II), querecetin-7-O-alpha-L-rhamnoside(III), isoorientin(IV), beta-sitosterol(V), beta-daucosterlo(VI).. Compound I, II, III, IV are isolated from genus Atriplex for the first time.
