| 摘 要： | 本文采用薄层层析和提取、分离、光谱分析等方法分析研究了三尖杉属植物叶的双黄酮类化合物，根据获得的化学分析结果，我们同意：(1)将三尖杉属分为二个组：篦子三尖杉组Sect．1 Pectinaea，只包括蓖子三尖杉一种；三尖杉组Sect．2 Cephalotaxus，包括本属所有其它种。(2)支持三尖杉科只包括三尖杉属1属，不支持将红豆杉科中的穗花杉属(Amentotaxus)归入三尖杉科的主张。(3) 认为三尖杉科与南洋杉科、松科、杉科和柏科的亲缘关系较远，而与红豆杉科及罗汉松科的亲缘关系密切。

| Abstract: | Bisflavone constituents of 6 species in the genus Cephalotaxus were analysed by dif-
ferent chemical methods. The result and some suggestions are as follows:
1. Fu's (1984) division of the genus Cephalotaxus into two sections, Cephalotaxus and Pec-
tinatea, is supported by the fact that oliveriflavone has so far been found only in Cephalotaxus
oliveri.
2. Our result is favourable to the opinion that Cephalotaxaceae is a natural taxon and inclu-
des only one genus, Cephalotaxus, but not to the placement of Amentotaxus of Taxaceae into
Cephalotaxaceae. Accroding to the literature and our analytical data, bisflavones and alkaloids
are the main constituents of Cephalotaxus, which have not been found in Amentotaxus of Taxa-
ceae.
3. Cephalotaxus is considered closely related to Taxaceae, and Podocarpaceae, but not clo-
sely related to Araucariaceae, Pinaceae, Taxodiaceae and Cupressaceae. Cephalotaxus, Taxaceae
and Podocarpaceae (expect for Podocarpus) only contain C-3'/C-8”-type of bisflavone constitu-
ents, whereas Araucariaceae, Taxodiaceae, and Cupressaceae, in addition to C-3'/C-8”-type of
bisflavone constituents, also contain many other bisflavone constituents, and bisflavone constitu-ents have not been found in Pinaceae. |
