摘要: 对永州市四种常见的野菜马齿苋、苦荬菜、车前和蕨菜的亚硝酸盐、硝酸盐、水分、粗蛋白、粗脂肪、粗纤维、维生素C等成分进行了测定和分析。结果表明:这四种野菜中粗蛋白、粗脂肪、粗纤维和维生素C含量高,前三者维生素C的含量甚至比白菜要高。苦荬菜、蕨菜中亚硝酸盐和硝酸盐含量较低,是可以放心食用的野菜。马齿苋和车前中硝酸盐的含量略超标,在烹饪时除采取一定的处理措施外,还要限量食用。

Abstract: Nitrite and nitrate, moisture, crude protein, crude fat, crude fiber, vitamin C and other ingredients contained in the four kinds of common potherb in Yongzhou, which are Portulaca Oleracea, Lactuca India, Plantago asiatica and Pteridium aquilinum, were determinated and analyzed. The results showed that the content of protein, fat, fiber and vitamin C were high; especially content of vitamin C was much higher than that of the cabbage, a kind of traditional vegetable. Content of nitrite and nitrate in Lactuca India and Plantago asiatica were lower enough for eating with safety. But Portulaca Oleracea and Pteridium aquilinum, because of slightly higher nitrate content when compared with standard, and should be limited in consumption, in addition to take certain measures when cooking.
