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.
