Abstract:Edible leaf and stem contents of Aspidopterys concava were analyzed to identify and quantitate its main nutritional components，mineral nutrients，and amino acids.The nutritional value and medicinal value of Aspidopterys concava were evaluated relative to the national food safety standard and China's health industry standard，and were reported here in terms of nutritional recommended intake percentage，amino acid ratio coefficient and amino acid ratio coefficient score.Compared with three other woody vegetables，Aspidopterys concava displayed higher nutritional value and richer content，particularly in protein（4.9 g/100 g），vitamin C（0.121 g/100 g-0.421 g/100 g），zinc（4.78 mg/kg-7.35 mg/kg），calcium（1 080 mg/kg-2 150 mg/kg），and magnesium（370 mg/kg-570 mg/kg）.Total amino acid content was 3.11 mg/kg-3.58 mg/kg，and essential amino acid content was 37.4%-42.4%.Both values were higher in Aspidopterys concava than those of three other common woody vegetables.However，the nutritional components of edible leaves and edible stems of Aspidopterys concava were not significantly different from those of the other woody vegetables.The contents of vitamin C，calcium，iron，magnesium and selenium in edible leaves were relatively dominant，and the amino acid composition was close to the nutritional values of the standard model.Aspidopterys concava has high nutritional content，balanced nutrition，rich flavor，and medicinal amino acids.
