The content of linoleic acid and oleic acid are 15.761% and 17.194% respectively. High performance liquid chromatography (HPLC) test shows that the total content of vitamin E in perilla oil is 500.9 mg/kg. Physicochemical properties test result shows that specific gravity is 0.928 8, refraction index1. 481 7, acid value 2.9 mg/g, iodine value1 980 g/kg, saponification value 190.7 mg/g, unsaponifiable matter 0.6%, moisture and volatile matter 0.07%, peroxide value 3.7 mmol/kg. So it is evident that perilla oil is a nutritive health care oil with great exploitation potentialities.
