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.
