摘要: 金樱子提取液在模拟胃液的pH酸性条件下对NO-2具有很强的清除作用。用0.1%柠檬酸作提取剂,在固液比为1:3、温度60℃,提取时间为1h所得的金樱子提取液对NO-2有87%以上的清除率;浸出液中的VC、还原糖、黄酮等对NO-2的清除有重要作用;浸出液在低pH值(pH2~3)下对NO-2清除作用强烈,随pH值升高,清除能力急剧下降。

Abstract: The extract of Rosa Laevigata Michx to remove great part of NO-2 in the duplicating pH condition as gastric juice.It eliminated more than 87 percent of nitrous acid in the optimum extraction conditions:0.1% citric acid as extraction solvent,the ratio of solid and liquid 1 to 3,60℃ temp. and 1 hour extraction time.The elements of Rosa Laevigata Michx extracts such as vitamin C,reducing sugar and flavonoid to work to remove NO-2.When in low pH (pH2~3),it has great capability of eliminating NO-2,but with increasing of the pH value,the capability of clearing up reduced sharply.
