摘　　要：目的:用索氏提取法提取革叶耳蕨叶的脂肪酸成分。方法:甲酯化处理后,采用气相色谱-质谱联用技术首次对该耳蕨叶中脂肪酸成分进行分析和鉴定。结果:发现该耳蕨叶主要的脂肪酸成分是:油酸(25.37%)、棕榈酸(16.18%)、亚油酸(10.92%)和植醇(10.96%)。结论:油酸和亚油酸是革叶耳蕨叶的药效成分。Objective： To investigate the fatty acids in Polystichum neolobatum Nakal. Methods： The fatty acids in leaves of P.neolobatum Nakal were extracted by Soxet extraction.The extracted fatty acids were esterified and then analyzed by GC-MS for the first time. Results： The main constituents of fatty acids in leaves of P.neolobatum Nakal were（Z）-9-octadecenoic acid（25.37%）,n-hexadecanoic acid（16.18%）,9,12-octadecadienoic acid（10.92%） and phytol（10.96%） Conclusion： （Z）-9-octadecenoic acid and 9,12-octadecadienoic acid are the main components of the fatty acids in the leaves of P.neolobatum Nakal which have the value for medical use.
