山西汾河滩常见野菜安全可食性的探讨

对采自汾河滩的七种野菜的硝酸盐、亚硝酸盐、维生素C和氨基酸的测定及统计分析结果表明:刺儿菜、藜、碱蓬的硝酸盐与亚硝酸盐含量较高,且其亚硝酸盐含量均超标,不宜食用;苦荬菜,其硝酸盐与亚硝酸盐含量稍微超过限量标准,但是其维生素C含量极其丰富,若两食量作一定的限制,是可以安全食用的;而地肤、车前、苦菜这三种野菜其硝酸盐与亚硝酸含量均较低,且维生素C及氨基酸两项营养价值指标适中,为安全可食性野菜。

Studies on safe edibility of common wild vegetables in Fenhe beach

The contents of nitrate,nitrite,vitamin C and amino acid in leaves of seven wild vegetables,which were collected from Fenhe beach,Shanxi Province, were determined. The results indicates that not all of these plants are safely edible. Cirsium segetum,Chenopodium album and Suaeda glauca are not edible because of higher contents of nitrate and nitrite; Although the contents of nitrate and nitrite in I xeris denticulate slightly exceed the limited standard.it is also safely edible for higher Vc content if the diet is correct. While Kochia scoparia ,Plantago depressa and Ixeris chinensis have good quality becarse of lower contents of nitrate and nitrite, and medium contents of Vc and amino acid.
