Four new water-soluble constituents, oblongaroside A (1), oblongar ester A (2), oblongaroside B (3), and oblongaroside C (4), were isolated along with four known compounds: 4-O--d-glucopyranosyl-3-hydroxybenzalcohol (5), 7-methoxyl-4-O--d-glucopyranosyl-3-hydroxybenzalcohol (6), 4-O--d-glucopyranosyl-3-hydroxybenzoic acid (7), and 3,4-dihydroxybenzoic acid (8) from the leaves of Ilex oblonga. Identification of their structures was achieved by 1D and 2D NMR experiments, including 1H-1H COSY, NOESY, HMQC, and HMBC methods and FAB mass spectral data.
