Triterpene Saponins from the Leaves of Ilex pernyi

AIM: To study the chemical constituents from the leaves of Ilex pernyi. METHODS: The chemical constituents were isolated by various column chromatographic methods and their structures were identified by spectral data together with physicochemical analysis. RESULTS Nine known compounds were isolated and identified as 2α 3β, 23-trihydroxyurs-12-en-28-oic acid β-D-glucopyranosyl ester (1), hederagenin 3-O-β-D-glucopyranosyl-(1→2)-O-α-L-arabinopyranoside (2), hederagenin 3-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranoside (3), hederagenin 3-O-β-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranoside (4), 3-O-β-D-glucopyranosyl-23-hydroxyursolic acid (5), chikusetsusaponin Ⅳa (6), 3β-23-dihydroxy-urs-12-en-28-oic acid 3-O-β-D-glucuronopyranoside 6'-O-methyl ester (7), ilexoside XXXVII (8), 3-O-β-D-glucuronopyranosyl-2α, 3β 23-trihydroxyurs-12-en-28-oic acid β-D-glucopyranosyl ester (9). CONCLUSION: The nine compounds were isolated from this plant for the first time.
