A new triterpenoid, methyl 2α-(4-hydroxybenzoyl)oxy-3β-hydroxy-urs-12-en-28-oate (1), has been isolated from the leaves of Eriobotrya deflexa f. deflexa, together with five known compounds, quercetin (2), kaempferol 3-O-β-glucoside (3), naringenin (4), ursolic acid (5), and euscaphic acid (6). The structure of new compound 1 was determined through spectroscopic and MS analyses. Among the isolates, quercetin (2), naringenin (4), and ursolic acid (5) showed potent inhibition with IC50 values of 31.74 ± 1.87, 24.25 ± 1.68, and 18.05 ± 1.02 μM, respectively, against LPS-induced NO generation.
