Four new triterpenes from Ilex cornuta Lindley

Two new lupane-type triterpenes, 24β-hydroxylupenone (1) and 3β-hydroxy-lup-20(29)-en-24-al (2), and two new ursane-type triterpenes, 28-formyloxy–3β-hydroxy-urs-12-ene (3) and 28-formyloxy-3β-acetoxy-urs-12-ene (4), together with 26 known triterpenes (5–30) were isolated from the leaves and trunk of Ilex cornuta Lindl. The structures of the new compounds were determined by spectroscopic methods, including 1D, 2D NMR (COSY, HMQC, HMBC, and NOESY), and HRMS data.
