A new kaurane-type diterpene lactone, tripterifordin [1], has been isolated from the roots of Tripterygium wilfordii. The structure of 1 was elucidated by spectroscopic methods, including the concerted application of a number of 2D nmr techniques that involved the 1H-1H COSY, heteronucleus-detected variants of the heteronuclear chemical shift correlation (HETCOR), phase-sensitive NOESY, and long-range HETCOR. Compound 1 shows anti-HIV replication activity in H9 lymphocyte cells with an EC50 of 1 microgram/ml.
从雷公藤根中分离出一种新的贝壳杉烷型二萜内酯，雷公藤内酯醇[1]。通过光谱方法阐明了化合物1的结构，包括协同应用多种二维核磁共振技术，其中涉及1H-1H COSY、异核化学位移相关（HETCOR）的异核检测变体、相敏NOESY和远程HETCOR。化合物1在H9淋巴细胞中显示出抗HIV复制活性，EC50为1微克/毫升。
