Comparative Determination of Fatty Acids in Pine Pollen from Different Varieties by GC-MS

Abstract

Abstract: A GC-MS method for the determination of fatty acids in pine pollen was established using Soxhlet extraction, methyl esterification and GC-MS and applied to comparatively analyze the relative contents of 12 main fatty acids in pone pollen from different varieties. This method provided a rapid, effective strategy for the determination of fatty acids in pine pollen. Except palmitic acid and heptadecanoic acid, all other 10 identified fatty acids showed a significant difference in their relative average contents (P ＜0.05). Moreover, both the relative average contents of saturated and unsaturated fatty acids exhibited a highly significant difference among five investigated varieties of pine pollens (P ＜ 0.01).

Key words: pine pollen, fatty acid, GC-MS
