Study on the chemical constituents of roots and stems of Nardostachys chinensis

Objective: To study the chemical constituents of roots and stems of Nardostachys chinensis.Methods: The chemical constituents were isolated and purified by column chromatography including silica gel,Diaion HP-20,Sephadex LH-20,ODS,and HPLC.Their structures were elucidated on the basis of spectral data analyses.Results: Six compounds were isolated and identified as 8-hydroxypinoresinol-4-O-β-D-glucopyranoside(1),8-hydroxypinoresinol-4′-O-β-D-glucopyranoside(2),8-hydroxypinoresinol-4-O-(β-D-glucopyranosyl)-4′-O-β-D-glucopyranoside(3),cycloolivil 6-O-β-D-glucopyranoside(4),ferulic acid(5),chlorogenic acid methyl ester(6).Conclusion: All the compounds are isolated from this genus for the first time.
