Four novel nortriterpenoids, henridilactones A−D ( 1 − 4 ), members of a very rare highly oxidized cycloartane skeletal class with a biosynthetically modified eight‐membered ring D, were isolated from the leaves and stems of Schisandra henryi var . yunnanensis . Their structures were elucidated using extensive spectroscopic techniques including 1D and 2D NMR spectra. Eight known triterpenoids were also isolated from the same source.
