摘要
用超声提取法提取,比色法测定,对10个省区绞股蓝的皂甙含量进行比较分析。结果表明,绞股蓝根部皂甙最高含量为7.75%,最低为0.68%;茎部皂甙最高含量为4.65%,最低为1.02%;叶部皂甙最高含量为6.86%,最低为2.03%。省区和绞股蓝皂甙含量之间没有相关性,地区差异导致的环境因子多样性是皂甙含量差异的主要原因。
Comparison and analysis of gypenosides content of Gynostemma pentaphyllum in 10 provinces was made by means of microwave-assisted extraction and colorimetry determination. Of all the samples the highest gypenosides content was 7.75% and the lowest 0.68% in the root; the highest 4.65% and the lowest 1.02% in the stem; the highest 6.86% and the lowest 2.03% in the leaves. The gypenosides content was not correlated to the provinces where G. pentaphyllum was collected and analyzed. The diversity of environmental factors resulted from regional difference is responsible for the difference in gypenosides content.
