title: Two new triterpenoids from the carpophore of Xanthoceras sorbifolia Bunge.
abstract: 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).
