华南主要野生蔬菜的基本营养成分及营养价值评价

对华南主要的8种野生蔬菜守宫木、土人参、一点红、白仔菜、紫背菜、鳄嘴花、藤三七、塘葛菜和华南特产蔬菜菜心的基本营养成分作了较全面系统的分析。结果表明，8种野菜营养成分差异较大，其可食部分都含有较丰富的灰分、粗蛋白、粗脂肪、粗纤维和VC含量。8种野菜中检测出钾、磷、钙、镁、钠、铁、锌、锰、铜、镍、铅、镉、铬等无机元素，其中钾含量比菜心高3－6倍，为高钾低钠植物。守宫木、白仔菜、鳄嘴花等对有毒重金属的富集能力较强。

Assessment Study on Nutritive Compositions and Value of Main Wild Vegetables in South China

The nutritive compositions of 8 kinds of main wild vegetables such as Sauropus androgynus, Talinum paniculatum, Emilia sonchifolia, Gynura divaricata, Gynura bicolor, Clinacathus nutaus, Anredera cordifolia and Nasturtium montanum were studied in South China. The results showed that the nutritive compositions of 8 kinds of wild vegetables were quite different. They were rich in ash, crude protein, crude fat, crude fiber and vitamin C content. They all contained potassium, phosphorus, calcium, magnesium, sodium, iron, zinc, manganese, copper, nickel, lead, cadmium and chromium. They were of high potassium and low sodium plants, and the content of potassium was 3 to 6 times higher than that of Brassica parachinensis. However, the content of lead exceeded the standard in Sauropus androgynus, Gynura divaricata and Clinacathus nutaus.
