- Abstract
Free radical damage is one of the important radiation-induced hurt on human body in Long-term Manned Space Flight. We studied Anthocyanins extracted from three Berries ({\it Lonicera caerulea}, {\it Vaccinium uliginosum Linn}． and {\it Rubus idaeus }) for their free radical scavenging activity in vitro, with Ascorbic Acid (Vc) as positive controls. These extracts were found to show remarkable scavenging activity on superoxide anion(•O2-), hydrogen peroxide (•OH-), 2,2-Diphenyl-1-picrylhydrazyl(DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)，as well as a high and dose-dependent reducing power. The EC50 of Lonicera caerulea Anthocyanin for •O2-, •OH-, DPPH and ABTS were respectively 1.56(S.D. 0.17)mg/ml, 0.028(S.D. 0.002) mg/ml, 0.030(S.D. 0.002)mg/ml, 0.080(S.D. 0.003)mg/ml. Vaccinium uliginosum Linn．were 1.43(S.D.0.22) mg/ml, 0.017(S.D.0.002) mg/ml, 0.035(S.D.0.005) mg/ml, 0.10(S.D.0.002) mg/ml. Rubus idaeus were 2.12(S.D. 0.032) mg/ml, 0.048(S.D.0.002 )mg/ml, 0.050(S.D. 0.002)mg/ml, 0.104(S.D.0.004) mg/ml. Ascorbic Acid were 0.072 (S.D. 0.003) mg/ml, 0.189 (S.D.0.012)mg/ml, 0.006 (S.D. 0.0001) mg/ml, 0.043 (S.D. 0.002)mg/ml. These results suggest that these tree anthocyanins are beneficial for human health and can be designed into space food as natural antioxidants supplementary.- Abstract document
