Fagopyrum tataricum

Fagopyrum tataricum, also known as Tartary buckwheat,[2] green buckwheat,[3] ku qiao,[3] Tatar buckwheat, or bitter buckwheat,[4] is a domesticated food plant in the genus Fagopyrum in the family Polygonaceae. With another species in the same genus, common buckwheat, it is often counted as a cereal, but unlike the true cereals the buckwheats are not members of the grass family. Thus, they are not related to true wheat. Tartary buckwheat is more bitter and contains more rutin than common buckwheat. It also contains quercitrin.[5]

The plant has been cultivated in many parts of the world; however, when found among other crops it is considered a weed.[7][8]

Chemistry

Fagopyrum tataricum contains aromatic substances. The most important difference when compared to the aroma of Fagopyrum esculentum is the absence of salicylaldehyde and presence of naphthalene.[9]
