摘要： 为探究不同品种香榧种子含油量及组成的差异，对同一产地不同品种的11种香榧（旋纹榧、茄榧、大圆榧、米榧、象牙榧、芝麻榧、普通榧、木榧、小圆榧、炭盆榧和寸金榧）种子的含油量以及种子油脂肪酸组成进行了对比研究，结果表明：不同品种的香榧种子含油量及种子油脂肪酸类型都表现出明显差异。11种不同香榧种子含油量约2%~14%，普通榧最高（13.4%），炭盆榧最低（2.2%）；脂肪酸种类最少8个，最多13个（寸金榧和木榧）。香榧种子油以不饱和脂肪酸为主，其总量超过66%。普通榧不饱和脂肪酸总量达到85.87%，其中主要成分油酸、亚油酸总量超过72%。所有品种的香榧种子油都含有超过6.90%的特殊脂肪酸金松酸，而且以普通榧中含量最高，达到10.41%。

Abstract: Comparative studies on contents and fatty acid compositions of seed oil extracted from 11 different kind of Torreya grandis from the same origin were carried out with the purpose of investigating the differences of these two aspects among different species, and the results indicated that the two sides of them substantially varied in accordance with species. The range of oil contents was from 2% to 14%, and the maximum was 13.4% for T.grandis Fort.while the minimum was 2.3% for T. grandis var.majus. The number of fatty acids ranged from 8 to 13. The major constituent of Torreya seed oils was unsaturated fatty acid, the total contents of which were more than 66% with the highest value 85.87% for T.grandis Fort., the major compositions of which were oleic acid and linoleic acid accounted for more than 72%. All species of T.grandis seed oils contained a special fatty acid called sciadonic acid taking a proportion more than 6.90%, and the top was 10.41% for T.grandis Fort..

Key words: Torreya grandis species, seed oil of T. grandis, fatty acid, sciadonic acid
