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)-β-d-fucopyranosyl theasapogenol B (1) and 3β,23-dihyroxy-lup-20(29)en-28-oic acid -23-caffeate (2).
