ABSTRACT
A new δ-oleanane-type triterpenoid glycoside, 3-O-(3-O-sulfo)-β-D-glucopyranosiduronic acid 3β-hydroxy-13(18)-oleanen- 28-oic acid 28-β-D-glucopyranosyl ester (1), along with ten known triterpenoid glycosides, rotundinoside A (2), oblonganoside M (3), 3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl 3β,19α-dihydroxy-20α- urs-12-en-28-oic acid 28-O-β-D- glucopyranosyl ester (4), ilexsaponin B2 (5), ilexside Ⅱ (6), rotundinoside B (7), ilekudinoside B (8), ilexpublesnin E (9), ilekudinoside D (10) and ilexpernoside D (11), was isolated from the 75% ethanol extract of the roots of Ilex asprella by various chromatographic separation. Their structures were identified on the basis of MS, NMR spectroscopic analysis and chemical methods. In addition, 2-11 were isolated from I. asprella for the first time.
