| 通过对马尾松、云南松和红松3种常见松子的主要组分进行分析，得出马尾松是制备松子油的一种理想原料。采用离心分离法提取松子油，在单因素试验的基础上，通过正交试验对其工艺条件进行优化，并对得到的松子油理化性质进行测定；通过GC-MS对马尾松、云南松和红松3种松子油脂肪酸组成进行测定。结果表明：松子油最佳提取工艺条件为加热温度85?℃，离心转速6 500 r/min，离心时间10 min；在此条件下松子油的提取率为60.54%，得率为37.53%，所得松子油理化指标符合国标植物油卫生标准。以亚麻酸和皮诺敛酸标准品进行定性分析，得出松子油中的十八碳三烯酸主要为皮诺敛酸，3种松子油皮诺敛酸的相对含量分别为20.61%、19.35%和1565%，其中马尾松松子油中皮诺敛酸的相对含量最高。 |

| The main components of P. massoniana, P. yunnanensis and P. koraiensis were analyzed, and P. massoniana was an ideal raw material for preparation of pine nut oil. The extraction conditions were optimized by orthogonal experiment based on single factor experiment, and the physicochemical properties of the pine nut oil obtained by centrifugation separation were determined. GC-MS was used to analyze the fatty acid composition of three species of pine nut oils of P. massoniana, P.yunnanensis and P.koraiensis. The results showed that the optimal extraction conditions were obtained as follows: heating temperature 85?℃, centrifugation speed 6 500 r/min, centrifugation time 10 min. Under these conditions, the extraction rate of pine nut oil was 60.54% and the yield was 37.53%. The physicochemical indicators of pine nut oil were in line with the national standard of vegetable oil health. The qualitative analysis of linolenic acid and pinolenic acid standards showed that pinolenic acid was the primary linolenic acid in pine nut oil, and the relative contents of pinolenic acid in three kinds of pine nut oils were 2061%, 1935% and 15.65% respectively, in which the relative content of pinolenic acid in P. massoniana was the highest. |
