摘要：
Two new triterpenoid saponins, hylonosides I-II (1,2) have been isolated along with one known flavonoid glycoside (3) from the methanol extract of leaves of Ilex hylonoma. The structures were elucidated by ID and 2D NMR experiments, including H-1-H-1 COSY, TOCSY, NOESY, HMQC, and HMBC methods. Two new compounds were characterized as 3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucuronopyranosyl pomolic acid-28-O-beta-D-glucopyranoside (1), 3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucuronopyranosyl pomolic acid-28-O-beta-D-glucopyranoside (2).
