金钱松Pseudolarix kaempferi的根皮在中药中称为“土荆皮”,用于治疗由真菌引起的皮肤病。从此植物中已分离得到了不同结构类型的二萜和三萜化合物,如:金钱松酸(pseudolaric acid)A、B是有效的细胞毒素。最近研究发现该植物种子的乙醚提取物在体外对组织培养的KB细胞显示明显的细胞毒活性,从该乙醚提取物中已经分离得到了两个新的二萜双内酯化合物金钱松内酯E(1)和金钱松内酯H(2)(pseudolarolide E、H)。本文报道了由相同乙醚提取物中得到的另一新的
The root bark of Pseudolarix kaempferi is known in Chinese medicine as “turpentine skin” and is used to treat skin diseases caused by fungi. Diterpenoid and triterpenoid compounds of different structures have been isolated from this plant, such as: pseudolaric acid A and B are effective cytotoxins. Recent studies have found that the ether extract of the plant seeds showed significant cytotoxic activity on tissue-cultured KB cells in vitro. Two new diterpene lactone compounds, llustroxolone E, have been isolated from the ether extract. (1) And lollisol lactone H(2) (pseudolarolide E, H). This article reports another new one from the same ether extract.
