【摘要】 目的:测定6种食用花卉中7种微量元素含量及水提率。方法:食用花卉经酸消化处理,原子吸收和原子荧光分光光度计测定微量元素含量,计算一、二次水提率。结果:Zn、Fe、Cu、Mn含量为:勿忘我18.997、35.5403、6.4076、23.5964 mg/g;白玉兰15.8357、28.9971、11.6545、43.6134 mg/g;玫瑰花21.6958、63.3192、7.2519、25.768 mg/g;金莲花24.2054、35.1003、13.3395、19.2709 mg/g;千日红22.9192、57.8898、8.1793、16.2395 mg/g;金盏菊26.085、180.9045、18.5369、22.1642 mg/g。6种食用花卉中Cd、Pb、As含量低于国家标准,总水提率在50%左右。结论:6种食用花卉中均含丰富的Zn、Fe、Cu、Mn,Cd、Pb、As含量低于国家卫生标准,可为食用花卉开发利用提供依据。更多还原

【Abstract】 Objective :Determination of seven kinds of trace elements in six kinds of edible flowers and the water extraction rate.Method: Edible flowers were digestion by acid,then determination of trace elements by atomic absorption spectrometry and atomic fluorescence spectrometry,and reckon the rate of water extraction.Result: The content of Zn,Fe,Cu,Mn were: Never self-forgetful 18.997,35.5403,6.4076,23.5964 mg/g;Yulan magnolia 15.8357,28.9971,11.6545,43.6134 mg/g;Rose 21.6958,63.3192,7.2519,25.768 mg/g;trollflower 24.2054,35.1003,13.3395,19.2709 mg/g;Gomphrena globosa 22.9192,57.8898,8.1793,16.2395 mg/g;Pot marigold 26.085,180.9045,18.5369,22.1642 mg/g.The content of Cd,Pb,As in six kinds of edible flowers is lower than the national standard,and the total extraction rate about 50%.Conclusion: There are rich inclusive of Zn,Fe,Cu,Mnin six kinds of edible flowers,the content of Cd,Pb,As is lower than the national health standard.It can provide the basis for development and utilization of edible flowers.更多还原
