摘要
从浙江省绞股蓝属植物的皂甙和黄酮类化合物的薄层色谱中选取25个数量化特征,对这些植物进行了数量分类。用最短距离法、最长距离法、中间距离法甲、中间距离法乙、重心法、类平均法和离差平方和法等系统聚类方法,探索了这些植物彼此间的亲缘关系。结果表明:浙江绞股蓝 G.sp 的形态和薄层色谱特征明显特殊,认为另成立新种较为合理。
The paper deals with the application of cluster analysis in classification of Herb
Gynostemmae in Zhejiang province.25 numerical characteristic features were obtained from thin
layer chromatogram of saponins and flavonoids.The coefficient of distance was used to show
quantitative index of similarity among OTUs.By means of systematic cluster methods—single
linkage method,complete linkage method,WPGMA(β=0),WPGMC(β=-0.25),centroid method
(UPGMC),group average method(UPGMA)and square sum method,seven dendrograms were
obtained from each method respectively.The results showed that seven dendrograms are identical
with the classical taxonomy,and UPGMA is the best among the methods.According to the
results,it is reasonable to separate G.sp.from G.pentaphyllum and to establish a new species
for it.
