摘要
探讨紫苏子和亚麻子油中的脂肪酸组成，为开发利用提供依据。方法：化学法萃取紫苏子和亚麻子油，ＧＣ／ＭＳ分析油中的脂肪酸成分。结果：紫苏子和亚麻子得油率（Ｗ／Ｗ）分别为２９．５２％和３８．９７％。紫苏子油中检出软脂酸、亚油酸、α－亚麻酸、硬脂酸、二十碳—烯酸和二十碳烷酸等６种脂肪酸，它们的相对百分含量分别为５．９１％、７．０３％、８４．５０％、２．４１％、０．０５％和０．１０％；亚麻子油中检出软脂酸、亚油酸、α－亚麻酸、硬脂酸和二十二碳烷酸等５种脂肪酸和２种未知成分，已知脂肪酸成分占总脂肪酸组分的９９．９１％，其相对百分含量分别为４．２９％、８．２０％、８３．８４％、３．５３％和０．０５％。结论：紫苏子和亚麻子油的脂肪酸组成均比较简单，并富含可开发利用的α－亚麻酸。
Purpose: The aim was to detect fatty acid constituent in both Perilla frutescens seed oil and Linseed oil for getting the useful data. Methods: The two oils were obtained by chemical extraction and their fatty acid components analyzed by GC/MS. Results: The content of two oils was 29. 52％ and 38. 97％ respectively. Six fatty acids (palmitic acid, linoleic acid, α-linolenic acid, stearic acid, eicosenoic acid and arachidic acid) were detected in Perilla frutescens seed oil. The relative percent of them was 5. 91％, 7. 03％, 84. 50 ％, 2. 41％, 0. 05％ and 0. 10％ respectively. Five fatty acids (palmitic acid, linoleic acid, α-linolenic acid, stearic acid and docosanoic acid) and 2 unknown constituents were detected in Linseed oil. The 5 fatty acids were 99. 91％ of the total constituents. The realtive percent of them was 4. 29％, 8. 20 %, 83. 84 % 3. 53 ％ and 0. 05 ％ respectively. Conclusion: Fatty acid constituent of both oils in Perilla frutescens seed and Linseed were very simple. simple.The relative percent of α-linolenic acid that can be used in the two oils was very high.
