摘要：

A new spirocyclic nortriterpene, 22-acetoxy-15-deoxo-eucosterol, was isolated together with a corresponding pentaglycoside from the bulbs of Veltheimia viridifolia. The structures of the isolated compounds were elucidated by spectroscopic methods including ID-and 2D-H-1 NMR,C-13 NMR, 1D-INEPT, 1D- and 2D-TOCSY, HSQC, HMBC, POESY experiments, FAB-and HPESI-mass spectrometry.
