Flavonoid contents of common buckwheat (cv. Kitawase) and tartary buckwheat (cv. Hokkai T 8, Hokkai T 9 and Hokkai T 10) were determined by high?performance liquid chromatography (HPLC). Moreover, they were measured at different plant developments such as 10, 18, 20, 22 and 30 days after sowing (DAS) and with plant parts including leaf, stem and flower harvested at 30 DAS. Total flavonoids including chlorogenic acid, four kinds of C-glycosylflavones (orientin, isoorientin, vitexin, isovitexin) and rutin of tartary buckwheats (range of 44.2-54.7, mean 44.2) were found 35% higher than those of common buckwheat (28.9 ㎎/g dry wt.). Among them, rutin was measured above 80% of total flavonoid contents. The other flavonoids (chlorogenic acid and four kinds of C-glycosylflavones) presented the highest level at 10 DAS and decreased according to plant developments. On the other hand, rutin content of Kitawase presented the highest level (33.6 ㎎/g dry wt.) at 22 DAS and decreased up to 30 DAS. Rutin content in tartary buckwheat temporarily decreased from 10 to 18 DAS and then reversely increased up to 30 DAS presented the highest level as ‘U’ curve. In Hokkai T 10, rutin content was found the highest level (53.8 ㎎/g dry wt.) at 30 DAS. In different plant parts harvested at 30 DAS, rutin content of leaf (range of 42.8-68.0, mean 57.0) was 5.3-fold higher than that of stem (range of 8.0-15.9, 10.8 ㎎/g dry wt.), regardless of cultivar. Significantly, rutin content (78.7) in the flower of Kitawase was 1.8 times higher than in the leaf and 9.8 times in the stem. Especially, chlorogenic acid content (14.6 ㎎/g dry wt.) in the flower of Kitawase was 63-fold higher than in the leaf, and 20-fold in the stem.
