The content of fatty oil in the seeds reached 14.70%. The main constituents of fatty acid were: oleic acid (44.37%), linoleic acid (40.378%), linolenic acid (0.867%),palmitic acid (4.525%),stearic acid (1.843%) etc,and the contents of unsaturated fatty acid reached 88.184%, the seed oil was of higher nutrient value. The contents of amino acids and mineral elements were relatively abundant. The content of total sugar of the fruits was rich also. And its fruits and seeds were of potential values in exploitation and utilization.展开更多
