摘要
为了增加西藏的坚果品种,发展西藏特色坚果经济。试验采用气相色谱法和原子吸收分光光度法对华山松籽仁中脂肪酸及微量元素进行测定与分析,并与陕西的华山松籽和常见坚果进行对比。结果发现,西藏华山松籽仁含油率为51.0%,油脂被检出10种脂肪酸,其中不饱和脂肪酸达91.257%,SFA、MUFA与PUFA质量比为1︰3︰7。多不饱和脂肪酸中亚油酸含量最高,接近于陕西被检出的最高含量,且高于油脂坚果核桃、杏仁、花生;籽仁中微量元素含量依次是镁>钙>铁>锰>锌>铜,其中铁、锰、锌含量高于核桃、杏仁、开心果、腰果和榛子。西藏华山松籽仁富含油脂及微量元素,是可开发的优质坚果资源。
For increasing the varieties of nuts and developing characteristic nut economic in Tibet, the fatty acid and trace elements of Pinus armandii seed in Tibet were measured and analyzed by using gas chromatography and atomic absorption spectrophotometry. Results showed that the oil content of the seed kernel of Pinus armandii in Tibet was 51.0%, and 10 fatty acids were detected. The unsaturated fatty acids were 91.257%, and the mass of SFA, MUFA and PUFA was 1︰3︰7. The linoleic acid content is the highest in the polyunsaturated fatty acids, and it＇s close to the highest level found in Shaanxi, and higher than that of Juglans regia, Prunus armeniacal and Arachis hypogaea. The content of trace elements in seed kernels in sequence is Mg〉Ca〉FeM〉n〉Zn〉Cu, which has higher content of Fe, Mn and Zn than that of Arachis hypogaea, Prunus armeniacal, Pistacia vera, Anacardium occidentalie and Corylus heterophylla. The Pinus armandii seed kernel is rich in oil and trace elements, which is a high quality nut resource in Tibet.
