摘要：

本文根据我们从银杉树干中分得的一类特殊成分——锯齿烯族七个化合物

及其在松科各属中的分布情况，讨论银杉属的系统位置。

银杉(Cathaya argyrophylla Chun er Kuang)是本世纪五十年代在我国发现的松科新

属(单种属)新种。银杉属自1958年被发表以来，分类学家和形态学家对该属在松科中

的系统位置一直颇感兴趣。根据形态结构特征，有些学者认为本属与松属、云杉属和黄杉

属接近，其系统位置可居于松属与云杉属或黄杉属之间。本文根据我们从银杉树干中

首次分离出来的已知锯齿烯族化合物，同松科各有关属进行比较，其结果与上述学者意

见基本相符合。

Abstract

The genus Cathaya discovered in Kwangsi, Sichuan, Hunan and Guizhou is endemic

in China. Only one species (C. argyrophylla Chun et Kuang) has so far been known

in the genus. The question on it’s systematic position in the family Pinaceae has been

much debated. However, according to some taxonomists and morphologists, this genus

is related to genera Pinus, Picea and Pseudotsuga of the Pinaceae.

No phytochemical data, especially of serratene components on Cathaya have been re-

corded. This paper deals with the systematic position of Cathaya in Pinaceae based

on seven known components of serratene family which are isolated from the trunk of

Cathaya argyrophyua growing in Sichuan.

A comparative study on serratene components of Cathaya with other genera of

Pinaceae showed that Cathaya is related to genera Pinus and Picea.
