Pinctada martensii is an important pearl-breeding shell for sea water pearls. In order to better develop and utilize the flesh of the Pinctada martensii, the fatty acid and ether-soluble components of Pinctada martensii flesh before and after pearl-nucleus-inserting were analysed by GC-MS. The results showed that: 13 fatty acids were identified in the Pinctada martensii flesh before and after pearl-nucleus-inserting, there was no difference in the fatty acids types between the two kinds of pearl-breeding shell, but the contents of fatty acids were different from each other, SFA,MUFA and PUFA in the flesh before pearl-nucleus-inserting were 34.51%, 14.31% and 31. 26% , MUFA and PUFA in the flesh after pearl-nucleus-inserting were 28. 88% , 8. 47% and 34. 11% ; 38 compounds were identified in the Pinctada martensii flesh before pearl-nucleus-inserting,and 37 compounds were identifiedin the Pinctada martensii flesh after pearl-nucleus-inserting, squalene was found in the flesh before pearl - nucleus-inserting. Thanks to the high level of unsaturated fatty acids and active substance such as squalene in the flesh, the flesh of Pinctada martensii has very high utilization value.%马氏珠母贝是目前中国用于海水珍珠生产的主要贝类.为了更好地开发利用马氏珠母贝贝肉,利用气相色谱－质谱(GC -MS)联用技术,对未插核和插核马氏珠母贝的贝肉脂肪酸和醚溶性成分进行了成分分析.结果显示:未插核贝和插核贝的脂肪酸的种类没有差异,都从中鉴定出了13种脂肪酸,但各种脂肪酸的含量存在差别,未插核贝的SFA、MUFA和PUFA的含量分别为:34.51％、14.31％和31.26％,插核贝中SFA、MUFA和PUFA的含量分别为:28.88％、8.47％和34.11％；在未插核贝的醚溶性成分中鉴定了38个化合物,在插核贝的醚溶性成分中鉴定了37个化合物,在未插核贝中发现了角鲨烯的存在,相对百分含量为5.22％.鉴于脂肪酸中高含量的不饱和脂肪酸以及醚溶性成分中的活性物质的存在,马氏珠母贝贝肉有很高的开发利用价值.
