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.
