摘要:

通过亚甲基蓝酵母染色法,测定大兴安岭地区5 种野生浆果水浸提液对酿酒酵母抗辐射的保护作用。随着紫外线辐射距离的增加、辐射时间的减短、浸提液质量浓度的提高、浆果抗紫外线辐射作用增强。大兴安岭地区常见5 种浆果抗微波和抗紫外线辐射的顺序为:野生蓝莓>红豆越橘>五味子>黑果花楸>树莓。在功率120 W微波辐射20 s时,5 种浆果浸提液的抗微波辐射能力在90%以上;功率380 W,微波处理时间为20 s时,野生蓝莓、红豆越橘、五味子浆果浸提液抗微波辐射能力依然在90%左右,黑果花楸、树莓浆果浸提液的抗微波辐射能力较弱;功率780 W,微波处理时间为40 s时,野生蓝莓抗微波辐射能力仍有84%,其余4 种浆果浸提液的抗微波辐射能力大幅度下降。实验表明,大兴安岭地区5 种常见浆果浸提液均具有抗微波和抗紫外线辐射作用,其中野生蓝莓抗辐射能力最强。

Abstract:

The anti-radiation effects of water extracts of five wild berries from the Daxinganling region of north China in
the yeast Saccharomyces cerevisiae when exposed to ultraviolet (UV) or microwave were determined through methylene
blue staining. The results showed that the anti-UV effect of berries on Saccharomyces cerevisiae became strong with
its increasing concentration, increasing radiation distance and decreasing radiation time. The order of anti-UV and antimicrowave
radiation effects of five berry varieties was blueberry > Vaccinium vitis-idaea L.> Schisandra chinensis > Aronia
melanocarpa > raspberry. The anti-microwave efficiency of all five berry varieties to 20 s microwave radiation at 120 W was
higher than 90%. When the microwave power was 380 W and the microwave treatment time was 20 s, the anti-microwave
efficiency of wild blueberry, Vaccinium vitis-idaea L. and Schisandra chinensis was approximately 90%, but the antimicrowave
efficiency of other berries was weaker. When the microwave radiation was carried out for 40 s at 780 W, the antimicrowave
capacity of blueberry was still 84%; however, the anti-microwave capacity of other berries significantly declined.
It is concluded that the five berry varieties grown in the Daxinganling region have anti-ultraviolet and anti-microwave
radiation capacity, of which blueberry provides the strongest protection from radiation.
