Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract The seed of Chinese torreya(Torreya grandis cv.Merrilli) is a special rare native nut in China.The extraction of torreya seed oil with the supercritical carbon dioxide technique was carried out.Then its fatty acid was analyzed by GC-MS,and compared with olive oil,peanut oil,camellia oil and sesame oil.Results showed that the obtained optimum extraction conditions were under the conditions of pressure 30 MPa,extraction temperature 50 ℃,and time 2 h,and extraction yield rate was 16.2%.Linoleic acid and oleic acid are most abundant with mass fraction of 38.23% and 35.52%,followed by palmitic acid(7.45%) and sciadonic acid(7.41%).Sciadonic acid was an unusual bio-active fatty acid.The fat acid components of torreya seed oil were similar to sesame oil and had the richest varieties among the five vegetable oils analyzed.The MUFA(36.39%) and PUFA(49.80%) in torreya seed oil were relatively balanced.These data would be helpful for the further development and utilization of Chinese torreya seed oil as functional food.
