The new compound hemsleyatine (1) was isolated along with four known C(19)-diterpenoid alkaloids: indaconitine (4), yunaconitine (5), chasmanine (6), and talatisamine (7) from the roots of Aconitum hemsleyanum PRITZ. Structures were established by spectral analysis, including tow dimeusional (2D) NMR spectroscopy and a chemical method. Hemsleyatine (1) is the first C(19)-diterpenoid alkaloid bearing the 8-amino group. In addition, the assignments of some (13)C signals for pseudaconine (3) were revised by comparison with those of hemsleyatine (1).
从滇西乌头(Aconitum hemsleyanum PRITZ.)的根中分离得到了新化合物滇西乌头碱(1)以及四种已知的C(19)-二萜生物碱:印乌碱(4)、云乌碱(5)、查斯曼宁(6)和塔拉胺(7)。通过光谱分析,包括二维(2D)核磁共振光谱和化学方法确定了结构。滇西乌头碱(1)是首个带有8-氨基的C(19)-二萜生物碱。此外,通过与滇西乌头碱(1)的信号进行比较,对伪乌头碱(3)的一些(13)C信号归属进行了修订。
