中国姜黄属植物根茎中姜黄素类化合物的含量测定

Determination of Curcuminoids Contained in the Rhizomes of Curcuma Genus from China by TLC Scanning Method

摘要: 在硅胶G板上,以正丁醉-26%氨水-无水乙醇(30:3:1)为展开剂,用薄层扫描法分离测定了中国姜黄属植物毛郁金Curcuma aromatica Salisb.,温郁金C. wenyujin Y. H. Chen et C.Ling(or C. aromatica cv. Wenyujin),莪术C. aeruginosa Roxb.,黄莪术C. zedoaria (Christm.)Rosc.,桂莪术C. kwangsiensis S. G. Lee et C. F. Liang,川郁金C. chuanyujin C. K. Hsich et H.Zhang,姜黄C. longa L.根茎中姜黄素(curcumin),去甲氧基姜黄素(demethoxycurcumin),双去甲氧基姜黄素(bisdemethoxycurcumin)和总姜黄素(curcuminoids)的含量,回收率97.07%～102.0%(n=6),变异系数为3.1%～5.0%。
