The sequences of ITS, matK, rbcL and psbA-trnH of 9 Gynostemma species or variety including 38 samples were compared and analyzed by molecular phylogeny method. Hemsleya macrosperma was designated as outgroup. The MP and NJ phylogenetic tree of Gynostemma was built based on ITS sequence, the results of PAUP phylogenetic analysis showed the following results: (1) The eight individuals of G. pentaphyllum var. pentaphyllum were not supported as monophyletic in the strict consensus trees and NJ trees. (2) It is suspected whether G. longipes and G. laxum should be classified as the independent species. (3)The classification of subgenus units of Gynostemma plants is supported.
采用分子系统发育方法，对包括38个样本的9种绞股蓝属植物或变种的ITS、matK、rbcL和psbA-trnH序列进行了比较分析。以大籽雪胆作为外类群。基于ITS序列构建了绞股蓝属的MP和NJ系统发育树，PAUP系统发育分析结果如下：（1）在严格合意树和NJ树中，绞股蓝五叶绞股蓝变种的8个个体不支持为单系类群。（2）怀疑长梗绞股蓝和疏花绞股蓝是否应分类为独立物种。（3）支持绞股蓝属植物亚属单位的分类。
