摘要
Fatty acid and amino acid composition of Eucommia ulmoides Oliver seeds were analyzed using Soxhlet extraction followed by GC-MS and automatic amino acid analyzer,respectively.Eucommia ulmoides Oliver seeds comprised 35.5% oil and 11 fatty acids were identified in the oil,mainly including linolic acid(10.66%),oleic acid(16.9%),palmitic acid(6.03%),stearic acid(1.96%),and linolenic acid(63.15%),among which,unsaturated fatty acids were dominant with relative content as high as 91.26% and hnolenic acid exhibited the highest content.A total of 25% protein was contained in Eucommia ulmoides Oliver seeds and the amino acid composition consisted of Asp,Glu,Ser,Arg,Gly,Thr,Pro,Ala,Val,Met,Ile,Leu,Phe,His,Lys,Tyr and Cys-Cys,among which,the contents of essential amino acids and semi-essential amino acids were higher,accounting for 33.6% and 11.2% of total amino acids,respectively.These results reveal a high utilization value of Eucommia ulmoides Oliver seeds as an exploitable source abundant in protein and unsaturated fatty acids.
