摘要
以湖南永州地区、湘西地区、张家界地区、娄底地区及四川甘孜地区这5个不同产地的多花黄精为试验材料,采用比色法对其多糖、总皂苷、总黄酮3种生物活性成分的含量进行了测定与分析比较。结果表明:多花黄精中的生物活性成分含量因产地不同而存在着较大差异,多糖含量在8.09%~11.78%范围内变化,以娄底地区的最高;总皂苷含量范围为2.73%~5.01%,以永州地区的最高;总黄酮含量范围为0.21%~0.71%,以张家界地区及四川甘孜地区的较高。总体来看,不同产地多花黄精中多糖含量均较高,总皂苷含量居中,总黄酮含量均较低。
Polygonatum cyrtonema Hua samples from Yongzhou,Xiangxi,Zhangjiajie and Loudi regions of Hunan,and Garzêregion of Sichuan were used as experimental material for the determination and comparison of their polysaccharide,total saponins and total flavonoids contents by colorimetric analysis method.The results showed that the contents of bioactive components in Polygonatum cyrtonema samples varied greatly with different habitats,polysaccharide content ranged from 8.09%to 11.78%,with the highest content from Loudi region;total saponins content ranged from 2.73%to 5.01%,with the highest from Yongzhou region;total flavonoids content ranged from 0.21%to 0.71%,which was relatively higher in Zhangjiajie region of Hunan and Garzêregion of Sichuan.In general,polysaccharide content of these Polygonatum cyrtonema samples is high,total saponins content is medium and total flavones content is low.
