Description:
Asprellols A–C ( 1 – 3 , resp.), three new 24-nortriterpenoids, were isolated from the CHCl 3 -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 β ,20 β -trihydroxy-3-oxo-11 α ,12 α -epoxy-24-norursa-1,4-dien-28,13 β -olide ( 1 ), 2,6 β -dihydroxy-3-oxo-11 α ,12 α -epoxy-24-norursa-1,4,20(30)-trien-28,13 β -olide ( 2 ), and 2,6 β -dihydroxy-3-oxo-11 α ,12 α -epoxy-24-noroleana-1,4-dien-28,13 β -olide ( 3 ) on the basis of spectroscopic analyses.
