39 kinds of wild vegetables were collected in the Chengde area.The contents of nitrate,nitrite and Vc in the edible part of them were determined.The result shows that:the content of nitrate in 20 kinds of wild vegetables among them are lower than the mild pollution standards,the other 19 kinds of wild vegetables are higher than that standards.After boiled by water,the content of nitrate and nitrite reduced greatly,they respectively decreased 72.32% and 66.48%.The contents of Vc in 39 kinds of wild vegetables are generally high.Among them,the content ofVc in 12 kinds of wild vegetables are higher than 100mg/100g.The Vc loss rate after boiled by water is 18%.
