Abstract

The physicochemical properties of Hovenia dulcis Thunb.seed oil were determined,and its fatty acids composition was analyzed by GC-MS.The results showed that the Hovenia dulcis Thunb.seed contained about 8.0% oil,in which the content of unsaturated fatty acids was over 87.46%,and the linolenic acid was about 45.56%.The physicochemical properties of the oil were as follows:refraction index(n20)1.478 9,relative density(d204) 0.918 7,iodine value 170.7 gI/100 g,saponification value 178.9 mgKOH/g.The Hovenia dulcis Thunb.seed oil had high nutritional value.
