cytellin and cardamonin

To study the chemical constituents in the whole plants of Sarcandra hainanensis.. The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.. Nine compounds, palmitic acid (1), icosanoic acid (2), beta-sitosterol (3), octadecanoic (4), acidchrysophanol (5), emodin (6), 2', 3'-dihydroxy-4', 6'-dimethoxychalcone (7), 2'-hydroxy4', 6'-dimethoxychalcone (8), cardamonin (9) were isolated and identified.. Compounds 1-9 were obtained from this plant for the first time. Compounds 2, 5-9 were isolated from family Chloranthaceae for the first time.

To study the chemical constituents from the ethanolic extract of Alpinia katsumadai Hayata.. The compounds were separated with the column chromatographic, and their structures were identified by chemical and spectroscopic methods.. Eight compounds were isolated from the ethanol extract. On the basis of their physical and chemical properties and spectroscopic analysis, the structures of seven compounds were identified. They were 1,7-Diphenyl-5-hydroxy-4, 6-heptadien-3-one(I), 1,7-Diphenyl4, 6-heptadien-3-one(II), Pinocembrin (III), Cardamomin (IV), Alpinetin (V), 7,4'-Dihydroxy-5-methoxy flavanones(VI) and beta-Sitosterol(VIII), respectively.. Compounds I , II and VII are separated from this plant for the first time. Compounds I and II are also obtained from this genus of Alpinetin for the first time.
