title: Lancifodilactones B-E, new nortriterpenes from Schisandra lancifolia.
abstract: Four new nortriterpenes, lancifodilactones B-E (1-4), were isolated from the leaves and stems of Schisandra lancifolia. Their structures were determined by analysis of 1D and 2D NMR spectroscopic data. These compounds are members of a new highly oxygenated cycloartane skeletal class with a biosynthetically modified eight-membered ring D.
