Two new rearranged lanostane triterpenoids, named tsugalide A (1) and tsugalide B (2), were isolated from the MeOH extract of the stem of Tsuga longibracteata Cheng. Their chemical structures of the new compounds were established on the basis of extensive 1D and 2D NMR spectroscopy, and the configuration of compound 1 was further confirmed by X-ray crystallography.
