| Abstract: | Objective To establish a method for determination of fatty acids in Apocynum honey by gas chromatography-mass spectrometry (GC-MS). Methods Fatty acids extracted by the mixture of hexane and aether were converted to methyl esters with KOH-CH3OH. Then the methyl esters were determined by the area normalizing method. Result There were 28 kinds of fatty acids in Apocynum honey, with the main components of linoleic acid (26.57%), palmitic acid (17.6%), and heptadecanoic acid (7.34%). The content of saturated fatty acid and polyunsaturated fatty acid were 38.83% and 61.17%, respectively. Conclusion Apocynum honey was rich in polyunsaturated fatty acid. This study provides scientific basis for exploitation and utilization of Apocynum honey. |
