21 チャラン科植物成分に関する研究 : ヒトリシズカのセスキテルペンラクトン類について [in Japanese] 21 STUDIES ON THE CONSTITUENTS OF CHLORANTHACEAE : SESQUITERPENE LACTONES OF CHLORANTHUS JAPONICUS SIEB [in Japanese]
Access this Article
A novel sesquiterpene lactone was isolated from Chloranthus japonicus Sieb. (Japanese name: Hitori-shizuka) and named shizukanolide (1). The structure of 1 was elucidated by physicochemical properties and X-ray diffraction analysis. The absolute configuration of shizukanolide was determined by chemical correlation with lindenene (4). Chloranthalactone A (2), the dehydro-compound of 1, was also isolated from C. japonicus. The stereochemical structure of 2 was established by correlation between the dihydro-compound of 1 and the tetrahydro-compound of 2. Furthermore, glechomanolid (3) was found in the same source. Chloranthalactone A was ascertained to have a remarkable antifungal activity against fungi of the genus Mucor and Rhizopus.
