The methanol extract of the dried stems of Celastrus stehanotifolius afforded two new triterpenes: lup-20(29)en-28-al-3β-yl caffeate (betulinaldehyde-3β-yl-caffeate) and olean-28-al-3β-yl caffeate, two new diterpenes: celaphanol A and celaphanol B, three known triterpenes: lup-20(29)en-28-ol-3β-yl caffeate (betulin-3β-yl-caffeate), lup-20(29)en-28-oic-3β-yl caffeate (betulinic acid-3β-yl-caffeate) and olean-3β-yl-caffeate, and one known diterpene: nimbidiol. Their structures were established on the basis of spectroscopic evidence.
