Abstract

機能性食品として注目される普通ソバ(Fagopyrum esculentum Moench)およびダッタンソバ(Fagopyrum tataricum Gaertn.)の果実(種子)における活性酸素消去能とその部位について検討した.活性酸素消去能は極微弱発光分析装置を用いて測定した.活性酸素消去能は普通ソバとダッタンソバでは有意な種間差異(P<0.01)が見られた.普通ソバでは品種間差が小さかった(P<0.05)のに対し, ダッタンソバでは2系統間に明瞭な差(P<0.01)が認められた.また普通ソバでは活性酸素消去活性が粉の部位より果皮や種皮の部位で高かったのに対し, ダッタンソバでは果皮や種皮よりも胚芽部で高かった.これらから普通ソバとダッタンソバでは活性酸素消去能の高い器官やその程度が大きく異なり, また消去反応に関わる物質が異なることが示唆された.

Intra and inter-specific differences for the distribution of antioxidant activity (AOA) in each seed obtained from two buckwheat species were detected by micro chemiluminesence from the sample with the H_2O_2-acetaldehyde mixed solution. In common buckwheat (Fagopyrum esculentum Moench), AOA of hull was higher than that of flour part, but in Tartary buckwheat (Fagopyrum tataricum Gaertn.), AOA of embryo was higher than other parts. There was a significant difference of seed- AOA characteristics between two buckwheat species (P<0.01), and were also varietal differences among these varieties of common (P<0.05) and Tartary buckwheats (P<0.01). These results indicated that the active sites for antioxidant function and the level of activity differed between common and Tartary buckwheat. The chemical compounds related to the activity seemed to differ between two species.
