Abstract From the roots of Pueraria lobata , two aromatic compounds have been obtained and their chemical structures have been characterized as but-2-enolides. In connection with this result, it has become apparent that the previous structures for pucrosides A, B and sophoroside A should be revised to related but-2-enolides.
摘要 从葛根根中获得了两种芳香族化合物,其化学结构为but-2-enolides。与此结果相关,很明显,先前的 pucrosides A、B 和槐糖苷 A 的结构应该修改为相关的 but-2-enolides。

The present invention relates to a new series of chemical compounds with a novel norneolignan skeleton (chemical formula I) possessing a biological activity on the central nervous system (CNS), especially memory-enhancing and acetylcholinesterase inhibitory activity, individually, or in combination thereof. The novel compounds of a new series have been named as Clitorienolactones. (The chemical formula should be inserted here.) wherein R1, R2 is H, OH or OCH3; Ring A and B may be mono- to polysubstituted
