Four new norsesquiterpenes wilfordonols A-D (1-4), along with three known compounds, sarmentol B (5), boscialin (6), and (+)-loliolide (7), were isolated from the leaves of Tripterygium wilfordii Hook.f.. The structures of the new compounds were elucidated on the basis of their spectroscopic analysis, and the absolute configuration of the compounds was confirmed by CD and modified Mosher's method. At a concentration of 10 μM, compounds 4, 6, and 7 inhibited signal transducer and activator of transcription 1 translocation by 34.27 ± 1.02%, 48.93 ± 1.76%, and 70.31 ± 2.20%, respectively.
从雷公藤（Tripterygium wilfordii Hook.f.）的叶子中分离出了四种新的降倍半萜wilfordonols A-D（1-4），以及三种已知化合物，即sarmentol B（5）、boscialin（6）和（+）-loliolide（7）。通过光谱分析阐明了新化合物的结构，并通过圆二色光谱（CD）和改良的莫舍尔方法确定了化合物的绝对构型。在浓度为10 μM时，化合物4、6和7分别抑制信号转导和转录激活因子1的易位34.27±1.02%、48.93±1.76%和70.31±2.20%。
