摘要
电离辐射会对人体健康造成严重损伤,本研究选取东北地区特有的五种浆果及黑木耳作为原料,旨在开发具有辐射防护功能的复合饮料。分别对蓝莓、红豆越橘、蓝靛果、沙棘和山荆子五种浆果,以及黑木耳中的活性成分进行提取,复合后测定复合物中活性物质含量,并测定了其总还原能力及对辐射后大鼠脾淋巴细胞的保护作用。结果显示,选择的10种复合物中,沙棘、蓝靛果、黑木耳复合物中的多酚、花色苷和黄酮含量最高,分别为(4.34±0.08)、(4.84±0.13)、(1.17±0.05)μg/mL;同时该复合物总还原能力也最强,并且具有最显著的辐射防护功能,当浓度为10mg/mL时,大鼠淋巴细胞存活率由辐射组的49.26%±1.21%提高至88.77%±2.53%。因此,人们可以通过饮用复合果汁来增强机体自身的抗氧化及辐射防护能力。
Lonizing radiation could lead to seriously damage on human health. This study selected five northeastern region-specific berries and auricularia auricular as raw material to develop of mixed beverage with radiation protection function. The active combination were extracted from blueberries （Vaccinium uliginosum L. ） ,red beans cranberries（Vaccinium vitis-idaea L.）,Lonicera edulis（Lonicera caerulea L.）,sea buckthorn（Hippophae rhamnoides L.） and mountain viticis（MaLus baccata L.） mature fruit,as well as auricularia auricular. The content of active combination in mixed ingredient was determined. The reducing power and the protective effect on rat spleen lymphocytes after radiation of the mixed ingredient were also measured. Results indicated that the combination of sea buckthorn,indigo fruit and black fungus possessed the highest content of polyphenols, anthocyanins and flavonoids,the contents were respectively （4.34±0.08）,（4.84±0.13） and （1.17±0.05）μg/mL. This combination also had highest reducing power and significant radiation protective activities. At the concentration of 10mg/mL,the survival of rat spleen lymphocytes was increased to 88.77% ±2.53% in mixed ingredient treated group compared to radiation group,which survival was only 49.26%±1.21%. Therefore,results indicated administrate the mixed beverage could enhance the antioxidant and anti-radiation activities of hunman body.
