Abstract: | Three new highly oxygenated nortriterpenoids, wilsonianadilactones A–C ( 1 – 3 ), together with twelve known ones, i.e., 4 – 15 , were isolated from the leaves and stems of Schisandra wilsoniana. Their structures were established by means of extensive analysis of spectroscopic data, and compound 1 was further confirmed by X‐ray crystallographic diffraction. Compounds 1 – 3 showed weak anti‐HIV‐1 activity with EC50 values of 23.5, 55.5, and 66.4 μg/ml, respectively. |
