青桐种子的含水量与化学成分分析及利用评价 GC . Firmiana platanifolia Seed Moisture Content and Chemical Composition Analysis and Evaluation

Abstract

In order to provide reference for proper storage,rational development and scientific use of F.platanifolia seeds,its moistture content and chemical composition were analyzed through the methods of oven drying,gas chromatograph,amino acid analyzer and ultraviolet spectrophotometry.The results showed that the seed moisture content was(10.23±0.12)%.And the seed soluble sugar content was(50.23±1.625 8)%,the crude fat content was(20.04±0.23)%.Seed crude fat contained four kinds of unsaturated fatty acid,made up 67.02% of the total.Among these unsaturated fatty acid,three kinds were necessary for human body,which were linoleic acid of 42.43%,linolenic acid of 0.67%,oleic acid of 22.85%.The seed contained 17 kinds of amino acids,among which the essential amino acids were seven kinds and counted for 30.94%.Conclusion: F.platanifolia seeds could be stored for 3~15 years.The seed had higher unsaturated fatty acid content and many kinds of amino acids.The nutritious seed could be developed and utilized as an important resources of medicinal vegetable oil
