摘要/Abstract

Abstract:

In this paper, 10 species and varieties of the genus Panax from China were

studied by means of numerical taxonomic methods. At first, the geometric approaches

and statistical treatments were used and some new characters induced by the funda-

mental characters were defined for the numerical representation of the morphological

characters of plants. Consequently, forty-seven morphological, three chemical, one geo-

graphical and one cytological characters were adopted. The principal component ana-

lysis and the similarity coefficients were computed on the standardized data. Based

upon the correlation matrix and the distance matrix respectively, the Q and R cluster

analyses were carried out, and UPGMA was used in both Q and R cluster analyses.

According to the R cluster analysis, all characters are mainly divided into 5 sets:

A, B, C, D and E (Fig. 2). The tree-like diagram illustrates that chemical constitu-

ents of triterpenoids and the chromosome numbers are related to some morphological

characters, such as the roots, the rhizomes, the seeds and the leaves. It is of interest to

note that the thicker the fleshy roots, the larger the seeds and the wider the teeth of

leaflet, the higher the content of the tetracyclic triterpenoids of dammarane type it

contains. On the other hand, the Q cluster analysis showed that Panax as a whole

may be divided into two groups (Fig. 3). The first group includes P. ginseng, P.

quinquefolius, P. notoginseng and P. zingiberensis and the second group includes P.

stipuleanatus, P. pseudo-ginseng, P. japonicus var. japonicus, P. japonicus var. angus-

tifolius, P. japonicus var. major and P. japonicus var. bipinnatifidus. The results of

the computation of principal component analysis indicate that the first principal

component consistes of the characters occurring in the sets A and B. It shows that

the variation in Panax has two opposite directions. One of them, corresponding to the

set A, is represented by the first group, and the other, corresponding to the set B, is

by the second group.

Finally, some questions about the use of the genus in medicine were discussed.
