摘要: 本文采用气相色谱定量分析了猕猴桃中有机酸含量。采用10%的硫酸甲醇对样品进行衍生化,用二氯甲烷萃取,最后进行气相色谱分析。结果表明,该方法的回收率高(93.8%~102.3%),相关性好(0.9991~0.9998),重复性好(RSD<5%)。猕猴桃中的有机酸主要是苹果酸、柠檬酸、棕榈酸、油酸和亚油酸等。

Abstract:  A method was developed for the quantitative analysis of organic acids in Actinidia chinensis by GC. The sample was etherified in 10% H2SO4-CH3OH, followed by extraction with CH2Cl2, and determined by GC. The results showed that method has high recovery(93.8%~102.3%), good correlation(0.9991~0.9998) and good reproducibility(RSD<5%). The main organic acids inA ctinidia chinensisa re:malic acid, citric acid, palmitic acid, oleic acid and linoleic acid.
