| The physicochemical properties of Bischofia polycarpa seed and its oil, and fatty acid composition of the seed oil were analyzed. The results showed that the 1 000 seeds weight, test weight, and contents of moisture,reduced sugar, total sugar, crude protein, crude fat and ash of the Bischofia polycarpa seed were 5.69 g, 936 g/L, 7.50%,0.68%, 1.55%, 3.64%, 30.3% and 4.31%, respectively. The acid value, peroxide value, iodine value, saponification value and unsaponifiable matter content of Bischofia polycarpa seed oil were 2.29 mgKOH/g, 10.7 mmol/kg, 132 gI/100 g, 159 mgKOH/g and 483%, respectively. Five kinds of fatty acids were mainly found in Bischofia polycarpa seed oil. The content of saturated fatty acids was only 11.72%, which was mainly composed of palmitic acid(6.91%) and stearic acid(4.81%). The content of unsaturated fatty acids was 88.28%, including linolenic acid(45.32%), linoleic acid(28.54%) and oleic acid(13.21%). The Bischofia polycarpa seed oil had high nutritional value, and was a kind of nutritional health oil with great development value. |
