摘要: 研究了桑叶中黄酮类化合物的微乳薄膜层析分离方法。用10%甲酸调酸,以含水量70%的十二烷基硫酸钠-正丁醇-正庚烷-水微乳液为展开剂,在聚酰胺薄膜上使桑叶黄酮类化合物分离。分离结果表明:桑叶乙醇提取物中分离出12个斑点,与用正丁醇-乙酸-水为展开剂的常规层析方法相比,微乳薄膜层析法的检测灵敏度更高,分离效果更好。

Abstract: This study proposes a method for the separation of flavonoids from mulberry leaves by microemulsion thin layer chromatography. By using 10% formic acid for the pH adjustment, as well as with SDS/n-C4H9OH/n-C7H16/H2O micromulsion containing 70% water as the eluant, on the polyamide spots, the flavonoids are separated by the proposed method. The results indicated that twelve spots can be obtained from ethanol extracts of mulberry leaves. It is also indicated that, compared with the common chromatography method with C4H9OH/CH3COOH/H2O as the eluant, the proposed microemulsion chromatography is of greater sensitivity of detection with better separation effect.
