摘  要:目的:研究缬草的黄酮类化学成分。方法:采用各种色谱方法分离纯化,通过测定理化常数和光谱分析鉴定黄酮类化合物的结构。结果:从缬草40%乙醇洗脱部位中分离并鉴定了10个黄酮类化合物,分别为:芹菜素-7-O-α-L-吡喃鼠李糖基(1→6)-β-D-吡喃葡萄糖苷(1)、8-甲基-芹菜素-7-O-β-D-吡喃葡萄糖基(1→2)-β-D-吡喃半乳糖苷(2)、6-甲基-芹菜素-7-O-α-L-吡喃鼠李糖基(1→6)-[α-L-吡喃鼠李糖基(1→2)]-β-D-吡喃葡萄糖苷(3)、金合欢素-7-O-α-L-吡喃鼠李糖基(1→6)-[α-L-吡喃鼠李糖基(1→2)]-β-D-吡喃葡萄糖苷(4)、金合欢素-7-O-α-L-吡喃鼠李糖基(1→6)-β-D-吡喃葡萄糖苷(5)、5-甲氧基-金合欢素-7-O-α-L-吡喃鼠李糖基(1→6)-β-D-吡喃葡萄糖苷(6)、5-甲氧基-金合欢素-7-O-α-L-吡喃鼠李糖基(1→6)-[α-L-吡喃鼠李糖基(1→2)]-β-D-吡喃葡萄糖苷(7)、4'-甲基-5-甲氧基-黄酮-7-O-α-L-吡喃鼠李糖基(1→6)-β-D-吡喃葡萄糖苷(8)、香叶木素-7-O-α-L-吡喃鼠李糖基(1→6)-β-D-吡喃葡萄糖苷(9)、8-羟基-香蜂草苷(10)。结论:所有化合物均为首次从该植物中分离得到。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.
