| 中文摘要: |
| 对重阳木种子的理化性质、种子油的理化性质及脂肪酸组成进行了分析。结果表明：重阳木种子千粒重、容重及水分、还原糖、总糖、粗蛋白质、粗脂肪和灰分含量分别为5.69 g、936 g/L、750%、0.68%、1.55%、3.64%、30.3%和4.31%；重阳木种子油的酸价（KOH）为2.29 mg/g、过氧化值为10.7 mmol/kg、碘值（I）为132 g/100 g、皂化值（KOH）为159 mg/g、不皂化物含量为483%；重阳木种子油主要由5种脂肪酸组成，饱和脂肪酸含量较低，仅占11.72%，主要为棕榈酸(6.91%)和硬脂酸(4.81%)，不饱和脂肪酸含量高达88.28%，主要为亚麻酸(45.32%)、亚油酸(28.54%)和油酸(13.21%)。重阳木种子油营养价值较高，是一种极具开发价值的营养保健油。 |

| 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. |
