1、刺梨果中多元酸和高级脂肪酸的分析研究|刺梨果 摘要:目的分析刺梨果中多元酸和高级脂肪酸的组成。方法采纳硫酸甲酯化处理刺梨果样品,用气相色谱-质谱联用(GC-MS)分析其多元酸和高级脂肪酸含量,用面积归一化法得出各有机酸的相对含量。结果共分别、鉴定22种酸性组分,占总峰面积的97.04%。结论刺梨果中高级脂肪酸和多元酸成分为:亚油酸(37.75%)、亚麻酸(19.51%)、油酸(15.15%)、棕榈酸(8.53%)、硬脂酸(4.12%)、枸橼酸(3.74%)和苹果酸(1.49%)等。 关键词:刺梨果;多元酸;高级脂肪酸;气相色谱-质谱 中图分类号:TS22.4文献标识码:A文章编号:1672-9
