摘要
目的:研究益母草Leonurus japonicus果实茺蔚子中的化学成分。方法:茺蔚子乙酸乙酯部位经硅胶,RP-18,Sephadex LH-20和HPLC等色谱技术分离纯化,根据理化常数和波谱数据鉴定化合物的结构。结果:分离鉴定了2个具有特殊骨架的28位去甲基齐墩果烷型螺环三萜。结论:化合物1为新化合物,命名为茺蔚子三萜A(leonujaponin A),化合物2为已知化合物,鉴定为phlomistetraol B,均为首次从益母草属植物中分离得到。
Objective: To study the chemical constituents from the fruits of Leonurus japonicus. Method: The compounds were extracted by 70% methanol, then isolated and purified by column chromatography on silica gel, RP-18, Sephedax LH-20 and HPLC. Their structures were determined on the basis of spectroscopic data and physicochemical property. Result: Two 28-noroleanane-derived spirocyclic triterpenoids including a new acylated nortriterpenoid were isolated and identified as (17R)-19 (18→17)-abeo-2a, 18β,23- trihydroxy-3fl-E-feruloyoxy-28-norolean-12-ene (1) and phlomistetraol B (2). Conclusion: Compound 1 is a new compound, named as leonujaponin A. Both compounds 1-2 are isolated for the first time from Leonurus plants.
