摘要：

Asprellols A-C (1-3, resp.), three new 24-nortriterpenoids, were isolated from the CHCl3-soluble fraction of 95% EtOH extract of the roots of Ilex asprella, together with a known nortriterpenoid. The structures of the new compounds were elucidated as 2,6,20-trihydroxy-3-oxo-11,12-epoxy-24-norursa-1,4-dien-28,13-olide (1), 2,6-dihydroxy-3-oxo-11,12-epoxy-24-norursa-1,4,20(30)-trien-28,13-olide (2), and 2,6-dihydroxy-3-oxo-11,12-epoxy-24-noroleana-1,4-dien-28,13-olide (3) on the basis of spectroscopic analyses.
