Abstract

In the paper,Trichasanthes kirilowii Maxim seed oil was extracted by soxhlet method,The fatty acid components in Trichasanthes kirilowii Maxim seed oil were methylated.These fatty acids composition were isolated and identified by gas chromatography-mass spectrometry,and its common physical chemical properties were analyzed.The result showed that the 19 fatty acids are identified in Trichasanthes kirilowii Maxim seed oil,which consist of 10saturated fatty acids(8.019%) and 9 unsaturated fatty acids(91.603%).Physical and chemical tests results showed that the kernel output ration is 55.8%,the extractionratio is 51.4%,the refractive index of the seed oil is 1.4831;the iodine value is120.9 gI2/100g,the acid value is 1.62 mg KOH/g,the saponification value is 190.2 mgKOH/g and POV is 0.85 meq/kg.As a healthy oil resource,it will have a profound developing potential.
