Abstract

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
