Objective:To investigate the chemical components of flavonoids of Valeriana officinalis.Methods:Various column chromatography were used in the isolation and purification,physiochemical constant determination and spectral analysis were adopted to determine the chemical structures of flavonoids.Results:Ten flavonoids were isolated from the 40% ethanol elution parts of Valeriana officinalis as apigenin-7-O-α-L-rhamnopyranosyl (1 →6)-β-D-glucopyranoside (1),8-methyl-apigenin-7-O-β-D-glucopyranosyl (1→2)-β-D-galactopyranoside (2),6-methyl-apigenin-7-O-α-L-rhamnopyranosyl (1 →6)-[α-L-rhamnopyranosyl (1 →2)]-β-D-glucopyranoside (3),acacetin-7-O-α-L-rhamnopyranosyl (1 →6)-[α-L-rhamnopyranosyl (1 →2)]-fβ-D-glucopyranoside (4),acacetin-7-O-α-L-rhamnopyranosyl (1 → 6)-β-D-glucopyranoside (5),5-methoxyl-acacetin-7-O-α-L-rhamnopyranosyl (1 → 6)-β-D-glucopyranoside (6),5-methoxyl-acacetin-7-O-cα-L-rhamnopyranosyl (1 →6)-[α-L-rhamnopyranosyl (1 →2)]-β-D-glucopyranoside (7),4'-methyl-5-methoxyl-flavone-7-O-α-L-rhamnopyranosyl (1→6)-β-D-glucopyranoside (8),diosmetin-7-O-ot-L-rhamnopyranosyl (1 →6)-β-D-glucopyranoside (9) and 8-hydroxyl-didymin(10).Conclusion:All the compounds are isolated from this plant for the first time.
