Abstract
A new lanostane triterpenoid (1) and two known (2, 3) analogues were isolated from Nothotsuga longibracteata. Their chemical structures were identified by spectral data including HR-ESI-MS, 1 D, and 2 D NMR. These lanostane triterpenoids showed no cytotoxic activities against three human tumour cell lines (A172, SHSY5Y, and Hela), but exhibited the activity of promoting the gastrointestinal motility of zebrafish treated with Nile red.
