Contents of Nitrate Nitrite and VC of Youngia japonica(L.) DC.

Abstract

Abstract: The contents of nitrate , nitrite and VC of Youngia japonica (L.) DC. in different growth period were determined and analysed. The results showed that: In different growth period, the contents of nitrate and nitrite change unlargely; In other periods, it belong to the first class edible wild vegetables and can be eaten anyway(in fresh, after salted or cooked ); But in flowering stage, it belong to the second class and can be eaten after cooked or salted; After scalding treatment in different time, the contents of nitrate, nitrite and VC in this wild vegetable were reduced gradually with the increase of the scalding time.

Key words: , wild vegetable； Youngia japonica (L.)DC； nitrate； nitrite； VC； scalding treatment；
