Abstract:
OBJECTIVE:To establish the gas chromatography(GC) for the content determination of ?-linolenic acid in songzi oil.METHODS:The separation was performed on 5% DEGS column with detector temperature at 220℃ and flow rate at 30ml/min,nitrogen gas was used as carrier.RESULTS:The linear range for ?-linoleic acid was 1.162～5.81mg/ml(r= 0.9 995).The average recovery was 97.95%(RSD=0.89%,n=3).CONCLUSION:This method was sensitive,accurate and reliable and suitable for the assaying of ?-linoleic acid in songzi oil.
