摘要：

本文根据唐松草植物所含化学成分并结合其外部形态及地理分布对属内各群的亲缘关系进行了

探讨。结果表明：(1)从化学系统学角度看，中国植物志中所安排的属内各组植物间的关系是适宜的。(2)植物中所含生物碱的种类及含量与植物的进化有一定关系。在较原始的组中，成分的类型和含量相对较少；而在较进化的组中，各种结构类型得到较大发展。(3)唐松草属在毛茛科中有较特殊的地位。在科内，它是联系蓇葖果和瘦果植物群的过渡类群；在科外，它使毛茛科与小檗科、防己科和罂粟科发生联系，使其成为一个自然的分类群。

Abstract:

According to chemical constituents, plant morphology and geographic distribution

of Thalictrum in China, the relationships among sections in the genus are discussed in the

present paper. The results show:

1. China is one of the major distribution centers of Thalictrum plants, with half of species

endemic. Compared with species in other regions of the world, Chinese ones are relatively

primitive.

2. From the chemosystematic point of view, the system of the genus adopted in Fl. Reip.

Pop. Sin. is reasonable.

3. The main constituents of Thalictrum plants are benzylisoquinoline alkaloids. A corre-

lation exists between the chemical patterns and plant evolution. The different sections are of

different structure types. Aporphine-benzylisoquinoline and bisbenzylisoquinoline are major

constituents in Sect. Leptostigma. Sect. Tripterium contains mainly aporphines, but

non-alkaloid compounds are principal constituents in several species. In Sects. Thalictum

and Schlagintweitella and Subgen. Leconyerium, types and content of alkaloids increase ob-

viously and thus there are medicinal species. So these sections should be interested in devel-

oping some active constituents of antitumor, hypotenstion and antibacterium.

4. The genus occupies a special position in Ranunculaceae, as a transition to link the

follicle plants and achene plants. Meanwhile, because the genus is rich in benzylisoquinoline

alkaloids, the opinion that the Ranunculaceae, Berberidaceae, Menispermaceae and

Papaveraceae form a natural group is even more strongly supported.
