苦荞麦根的化学成分研究

目的研究苦荞麦Fagopyrum tataricum根的化学成分。方法采用多种色谱技术进行分离精制,通过理化性质和波谱分析进行结构鉴定。结果从苦荞麦根中分离得到8个化合物,分别鉴定为5-羟甲基-2-呋喃甲醛(1)、香豆素(2)、()-甘草素(3)、酞酸双(2-乙基己基)酯(4)、对羟基苯甲醛(5)、香草醛(6)、6-羟基豆甾-4,22-二烯-3-酮(7)、2,5-二甲氧基苯醌(8)。结论所有化合物均为首次从荞麦属中分离得到。

Chemical constituents from roots of Fagopyrum tataricum

Objective To investigate the chemical constituents from the roots of Fagopyrum tataricum.Methods The solvent extraction together with column chromatography was used for the isolation of chemical constituents.The physicochemical characteristic and spectroscopic evidences were employed for structure identification.Results Eight compounds were isolated and identified as 5-hydroxymethyl-2-furfuraldehyde(1),coumarin(2),()-liquiritigenin(3),bis(2-ethylhexyl) benzene-1,2-dicarboxylate(4),p-hydroxybenzaldehyde(5),vanillin(6),6-hydroxystigmasta-4,22-dien-3-one(7),and 2,5-dimethoxybenzoquinone(8).Conclusion All compounds are isolated from the plants in genus Fagopyrum Mill.for the first time.
