摘　　要：以海南岛昌江县霸王岭种植基地的星油藤种子为材料,测定其水分、蛋白质、油脂及脂肪酸的含量。结果表明,海南星油藤是一种具有重要经济价值的藤本油料作物资源,其种子平均含水量为7.49%,蛋白质含量为27.41%,种子出油率为60.04%,属于高蛋白油脂种子;此外,通过气象色谱法共检测出5种脂肪酸,分别为棕榈酸、硬脂酸、油酸、亚油酸和亚麻酸,不饱和脂肪酸成分共占90.16%,其中人体必需的多不饱和脂肪酸占79.51%。Plukenetia volubilis seeds were collected from a Bawangling planting base,Changjiang county,Hainan province to determine their contents of water,proteins,oils and fatty acids. The results showed that the P.volubilis seeds contained 7. 49% of water and 27. 41% of protein and gave an oil yield of 60. 04% by average,which indicated that P. volubilis seeds were of high protein and oil. Five fatty acids including palmitic acid,stearic acid,oleic acid,linoleic acid and linolenic acid were identified in the P. volubilis seeds by using the gas chromatography system,The seeds contained 90. 16% of unsaturated fatty acids（ oleic acid,linoleic acid and linolenic acid）,and 79. 51% of polyunsaturated fatty acids（ linoleic acid and linolenic acid） which are essential for human body. The findings indicated that P. volubilis could be used as an important resource of liana oil plant.
