| 中文摘要: |
| 为研究怒江州不同产地漆油成分差异，比较传统工艺（手工）和现代工艺（机器压榨）制取漆油的优缺点，了解白漆油和黑漆油的区别，找到漆油中除脂肪酸外其他功能性成分，采用气相色谱-质谱（GC-MS）联用技术对怒江州漆油成分进行测定，并结合主成分分析(PCA)对怒江州4个不同产地漆油脂肪酸组成及含量进行分析。结果表明：怒江州4个不同产地漆油脂肪酸组成主要为饱和脂肪酸，其含量差异显著，泸水产地的漆油品质较优；传统工艺与现代工艺制取的漆油脂肪酸含量差异显著，但两种工艺各具优点；白漆油脂肪酸含量和黑漆油相差不大；从4个不同产地漆油样品中还检测到了壬二酸、十七烯、角鲨烯，其在工业生产、医疗保健等方面都具有重要作用 |
| 英文摘要: |
| In order to study the difference of lacquer oil component in different producing areas in Nujiang,compare the advantages and disadvantages of traditional(manual) and modern (machine-pressing) processes to produce lacquer oil, understand the differences between white lacquer oil and black lacquer oil,and find out other functional components in lacquer oil except fatty acid, the lacquer oil components in Nujiang were analyzed by gas chromatography-mass spectrometry(GC-MS)，and the fatty acid composition and content of lacquer oil from four different producing areas in Nujiang was evaluated by principal component analysis(PCA).The results showed that the fatty acids of lacquer oil from four different producing areas in Nujiang were mainly saturated fatty acid, but the contents were significantly different.The quality of lacquer oil in Lushui was better. The fatty acids contents in lacquer oil prepared by traditional process and mordern process were significantly different, and the two processes had their own advantages. There was little difference in the fatty acid content between white lacquer oil and black lacquer oil.Three ingredients, including azelaic acid, heptadecene and squalene, were detected from lacquer oil samples from four different producing areas, which played an important role in industrial production and medical care. |
