Two new triterpenoids from the carpophore of Xanthoceras sorbifolia Bunge.
Two new triterpenoids were isolated from the dried carpophore of Xanthoceras sorbifolia Bunge (Sapindaceae). By means of spectroscopic data (1D and 2D NMR, ESI-MS) and chemical evidence, their structures were established as 16-O-acetyl-21-O-(3',4'-di-O-angeloyl)-beta-D-fucopyranosyl theasapogenol B (1) and 3beta,23-dihyroxy-lup-20(29)en-28-oic acid -23-caffeate (2).
