Abstract:
Objective To study the chemical constituents of the defatted seeds of Camellia oleifera. Methods The chemical constituents were isolated and purified by column chromatography on silica gel, MPLC, and PHPLC. Their structures were elucidated on the basis of physicochemical properties and spectral analysis. Results Three compounds were isolated from the defatted seeds of C. oleifera and elucidated as 3β,15α,16α,22α,28-pentol-22-O-angeloyloxy-olean-12-ene-3-O-β-D-glucopyranosyl-(1→2)-β-D- xylopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-glucuronopyranoside-6-O-methyl ester (1), gordonoside R (2), and gordonoside Q (3). Conclusion Compound 1 is a new compound named camelliasaponin Ab, and compounds 2 and 3 are isolated from this plant for the first time.
