In the present study,three new triterpenoids,23-hydroxyurs-12,18-dien-28-oic acid 3β-O-α-L-arabinopyranoside (1),23-hydroxyurs-12,18-dien-28-oic acid 3β-O-β-D-glucuronopyranoside-6-O-methyl ester (2),and urs-12,18-dien-28-oic acid 3β-O-β-D-glucuronopyranoside-6-O-methyl ester (3),and a known triterpenoid,3β-hydroxy-urs-2,18-dien-28-oic acid (4,randialic acid B),were isolated from the aerial parts of Ilex cornuta.Their structures were identified by the spectroscopic analyses (IR,ESI-MS,HR-ESI-MS,and 1D and 2D NMR) and chemical reactions.Compound 4 showed significant cell-protective effects against H2O2-induced H9c2 cardiomyocyte injury.Compounds 1-4 did not show any significant DPPH radical scavenging activity.
