title: Two New 18-Norschiartane-type Schinortriterpenoids from Schisandra lancifolia.
abstract: Two new 18-norschiartane-type schinortriterpenoids, namely wuwezidilactones Q (1) and R (2) were isolated from the stems of Schisandra lancifolia. Their structures were determined on the basis of extensive spectroscopic analysis. The absolute configurations of the new compounds were further determined by ROESY and an empirical comparison of their experimental ECD spectra with literature.
