Research on Chemical Constituents of Seeds of Camellia pitardii

Objective: To study the chemical constituents of the seeds of Camellia pitardii.Method: Chemical constituents were isolated by various chromatographic methods and were identified by physicochemical characters and spectroscopic analysis or comparison with standard compounds.Result: From the EtOH extract of the seeds of C.pitardii,seven compounds were isolated and identified as kaempferol-3-O-[α-L-rhamnopyranosyl(1→3)-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside](1),kaempferol-3-O-[α-L-rhamnopyranosyl-(1→ 3)-(4'''-acetyl)-α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside](2),D-galactitol(3),sucrose(4),daucosterol(5),β-sitosterol(6),lupeol(7).Conclusion: Compounds 1-7 were obtained from the seeds of C.pitardii for the first time.
