白术药材的薄层色谱研究 |
[生化制药论文]
【摘要】 目的建立白术薄层色谱鉴别方法。方法以白术内酯Ⅲ为对照品,正己烷-醋酸乙酯(3.5∶1)为展开剂,10%硫酸乙醇显色后在波长366 nm下检识。结果白术药材薄层色谱中,在与对照品色谱相应位置上显相同颜色的荧光斑点。结论该方法准确、简便,可为白术的质量控制提供参考。
【关键词】 白术;薄层色谱鉴别
Abstract:ObjectiveTo establish the quality control method of Atractylodes macrocephalae.Methods AtraetylenolideⅢ was used as the reference substance and the mixture of n-hexane and ethyl acetate (3.5:1) as the mobile phase.An alcohol solution containing 10% sulfuric acid was used for colouration in the way of sprayin. The fluorescence chromatogram was detected at 366nm in the ultraviolet lamp house .ResultsThe spots in the chromatogram of the test solution corresponding to the position to atraetylenolideⅢ had the same colour.ConclusionThe method is accurate and simple,and can be used for the quality control of this plant .
Key words:Atractylodes macrocephalae; TLC 中药白术为菊科植物Atractylodes macrocephala Koidz.的干燥根茎,被《神农本草》列为上品,具有健脾益气、燥湿利水、止汗安胎功效。白术内酯Ⅲ是白术中的活性成分之一,经药理实验表明其有抗炎、抗癌作用[1~3];此外,苍术、白术两者同源,功效较为接近,古时常不分二术,直到张仲景之后,始将二者分开使用。本研究通过对两者进行薄层的图谱比较,确定白术内酯Ⅲ为可区分白术和苍术的成分之一。……
