Abstract: The contents of nitrate and Vitamin C of 5 kinds of common wild vegetables including Rorippa dubia，Plantago asiatica，Portulaca oleracea，Lactuca indica，Oenanthe javanica. in Shangrao, Jiangxi Province were determined. The results showed that the nitrate contents differed greatly, and respectively were: 26.76 mg/kg, 77.66 mg/kg, 22.92 mg/kg, 70.99 mg/kg and 1.54 mg/kg. All of them did not exceed the FAO / WHO acceptable daily required amount (ADI). There was less difference existing in Vitamin C contents among 5 wild vegetables.
