Objective:
To study the chemical composition from the leaves of Panax japonicus var. major.Methods:
Column chromatographies (including macroporous resin, silica gel, Sephadex LH-20 and ODS) and semi-preparative HPLC were used to separate the constituents. The structures were elucidated by the analysis of spectral data and chemical properties.Results:
Three compounds were isolated and elucidated as dammar-20(21),24-diene-3β,6α,12β-triol (1), dammar-20(22) Z,24-diene-3β,6α,12β-triol (2), and 3-O-[-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl]-20-O-[-β-D-xylopyranosyl-(1→6)-β-D-glucopyranosyl]-23E,25-diene- 20(S)-protopanoxadiol (3).Conclusion:
