Rutin, quercetin, and free amino acid analysis in buckwheat (Fagopyrum) seeds from different locations
“Rutin, quercetin, and free amino acid analysis in buckwheat (Fagopyrum) seeds from different locations”, vol. 14, pp. 19040-19048, 2015.
, In this study, five common buckwheats and nine tartary buckwheats grown at different locations were analyzed for the contents of rutin, quercetin, and amino acids by high-performance liquid chromatography and spectrophotometry. The rutin content was higher than quercetin in buckwheat seeds. Rutin content was in the range from 0.05 (0.05 g per 100 g dry seeds) to 1.35% of buckwheat seeds. Quercetin content varied from 0.01 to 0.17% and in some common buckwheats it was even difficult to detect.
