Alkaloids are major active constituents in Thalictrum plants in addition to a small amount of triterpene and flavonoids. The major pharmacological functions of the active constituents include： anti-tumor, anti- virus, antibiosis, antiphlogosis, hypotensive action, and etc. This paper summarizes the methods for determining the contents of chemical constituents in Thalictrum plants and new chemical constituents discovered in this genus in recent ten years.展开更多
Two new compounds, 5-hydro-N-methylcorydalidine (1) and 1-(4-methoxybenzyl)-2-N-methyl-6-hydroxyl-5, 7-dimethoxy-isoquinoline (2), together with seven known ones (3-9) were isolated from the chloroform extract of the ...Two new compounds, 5-hydro-N-methylcorydalidine (1) and 1-(4-methoxybenzyl)-2-N-methyl-6-hydroxyl-5, 7-dimethoxy-isoquinoline (2), together with seven known ones (3-9) were isolated from the chloroform extract of the herb Thalictrum delavayi Franch., among which compound 7 was firstly obtained from the genus Thalictrum. Their structures were elucidated on the basis of spectroscopic evidence including HMQC and HMBC experiments.展开更多

[Method] Based on Thalictrum foeniculaceum plants, morphological characters of the plants, and the paraffin sections and powders of dif- ferent organs were observed with an optical microscope. [Result] Cross-section of roots of Thalictrum foeniculaceum is typical secondary structure of dicotyledon and anticlinal wall of endodermis is curve. What＇s more, vessel type is diversified, in- cluding reticulate vessel, spiral vessel, and bordered pit vessel. In addition, the leaf can be classified into basal leaf and stem leaf, of which the former is ternate vein and bifacial leaf, and the latter is isolateral leaf. The cells in palisade tissue are 2-3 lists and small granules can be found in surface of leaf epidermal cells; pollen grain is round and scattered. [Conclusion] The research laid foundation for development of plant resources and formulation of quality standard for Thalictrum foeniculaceum.展开更多
