牡丹常见品种花瓣中主要营养成分与食用安全性分析

以洛阳牡丹常见的5个品种"凤丹白"、"日暮"、"赵粉"、"红株女"和"粉中冠"为试材,研究其盛花期花瓣中总糖、总蛋白、维生素C和5种元素(砷、铜、钒、硒、铬)的含量以及超氧化物歧化酶(SOD)的活力。结果表明:5个牡丹品种花瓣中均含有丰富的糖类、蛋白质和维生素C,并具有较高的SOD活力。"凤丹白"和"日暮"花瓣中砷元素、"赵粉"花瓣中硒元素、"红株女"和"粉中冠"花瓣中铬元素含量均略高于国家食品卫生标准中对蔬菜的限量标准,而作为粮食加工食品时,5个牡丹品种花瓣中的砷、铜、钒、硒、铬元素含量均低于或远低于国家限量标准。

Analysis of Nutritional Components and Safety for Eaten in Common Flowers of Peony

The contents index of total sugar,total protein and vitamin C and the contents of As,Cu,V,Se and Cr and the activity of Superoxide dismutase(SOD) in five common species of Luoyang blooming peony flowers were determined.The results showed that there were plenty of total sugar,total protein and vitamin C and high ctivity of SOD in the petals of the five peony species.But the As content in both Fengdanbai and Rimu petals,Se as in Zhaofen petals and Cr content in both Hongzhunv petals and Fenzhongguan petals were little hingher level than the limited national food hygiene standards.On the other hand,the contents index of As,Cu,V,Se and Cr in the five species were lower even far lower than the national standards as all the species were food supplies materials.
