红树植物红海榄脂肪酸的GC-MS分析

GC-MS Analysis of Fatty Acids in Mangrove Plant Rhizophora stylosa

摘要:

采用索氏提取法对红树植物红海榄(Rhizophora stylosa)叶中的脂肪酸进行提取，甲酯化后利用气相色谱－质谱联用仪对脂肪酸成分进行分离和鉴定，鉴定出了12种脂肪酸，占脂肪酸总量的84.95%，其中主要包括十六酸(棕榈酸)（40.49%）, 9-十八碳烯酸(油酸)（17.24%），9,12-十八碳二烯酸(亚油酸)（11.24%）等。

Abstract:

The fatty acids from the leaves of mangrove plant Rhizophora stylosa were extracted by Soxhlet extraction. The extracted fatty acids were esterified and analyzed by gas chromatography-mass spectrometry. Twelve fatty acids were detected and identified, amounting to 84.95% of the total fatty acids, mainly including palmitic acid (40.49%), oleic acid (17.24%) and linoleic acid (11.24%).
