GC-MS法分析黑鳞耳蕨叶的脂溶性成分

Analysis of Liposoluble Constituents in Leaves of Polystichum Makinoi Tagawa by GC-MS

目的:研究黑鳞耳蕨叶的脂溶性成分。方法:用索氏提取法提取黑鳞耳蕨叶的脂溶性成分,甲酯化处理后,采用气相色谱-质谱联用技术首次对其脂溶性成分进行分析和鉴定。结果:黑鳞耳蕨叶的主要脂溶性成分是油酸(22.88%),棕榈酸(15.11%),10,13-十八碳二烯酸(9.11%)和植物醇(8.46%)。结论:黑鳞耳蕨叶有药用价值。

Objective： To investigate the liposoluble constituents in leaves of Polystichum makinoi Tagawa. Method： The liposolu- ble constituents in leaves of P. makinoi Tagawa were extracted by Soxet extraction method. After esterification with methanol, the ex- tracted liposoluble constituents were then analyzed by GC-MS for the first time. Result： The results showed 9-octadecenoic acid （22.88%） , hexadecanoic acid （15.11% ） , 10 13-octadecadienoic acid （9.11% ） and phytol （8.46%） were the main liposoluble constituents in the leaves of P. makinoi Tagawa. Conclusion： The leaves of P. makinoi Tagawa show medicinal value.
