| 摘 要： | 采用甲酯化处理冬枣果肉，用GC—MS联用法进行分析，对山东沾化、河北黄骅、天津静海冬枣果肉中有机酸的化学组成与相对含量进行了对比试验。试验结果确认20种酸性成分，其中多元酸6种，脂肪酸14种，各产地的冬枣果肉中所含的有机酸种类基本相同，但含量有所差异，其中不饱和高级脂肪酸的含量较高，均在45％以上。

| Abstract: | Organic acids in winter jujube were determined by gas chromatographic-mass spectrometric method based on the transesterification procedure. Identification and quantitation of organic acids in winter jujubes were from three districts. The results showed that, 20 kinds of organic acid were identified, including 6 kinds polybasic acids, 14 kinds fatty acids. The districts did not significantly affect the kinds of organic acids. The amounts of organic acids present in winter jujubes from different districts was... |
