| Abstract: |
| 【Objective】 A complete analysis was carried out on nutritional and functional constituents in oil meal of Eucommia ulmoides seed to provide theoretical basis for the use and development of this resource.【Method】 Referring to national standards in China,conventional chemical methods and instrumental analytical methods were adopted to determine the contents of nutritional constituents,including minerals,saccharides,crude fats,proteins,and amino acids.Functional constituents,such as total flavonoids,chlorogenic acid,and aucubin,were measured by spectrophotometry and high performance liquid chromatography (HPLC).【Result】 The contents of proteins,saccharides and curde fats in oil meal of E.ulmoides seed were 337.50,140.00,and 16.50 g/kg,respectively.The contents of potassium,sodium,calcium,and iron were 11.2,0.014,4.2,and 0.38 g/kg,respectively,indicating characteristics of high protein,low lipids,high potassium,and low sodium.The contents of vitamin B1 and B2 were 6.30 and 3.18 mg/kg,respectively.Seventeen amino acids were detected with a total content of 214.9 g/kg,in which the content of essential amino acids was 66.0 g/kg.For functional constituents,the contents of aucubin,total flavonoids,and chlorogenic acid were 137.6,0.61,and 1.00 g/kg,respectively.【Conclusion】 The oil meal of E.ulmoides seed demonstrated high values for the use and development manifested by its nutritional and functional constituents. |
