药用白菊花4个栽培类型农药与重金属残留的比较研究

Comparative Study on Pesticide and Heavy Metal Residuals ofFour Cultivars ofChrysanthemum morifolium

目的 :通过对药用白菊花 4个栽培类型重金属与农药残留的比较研究 ,为药用白菊花品种选择提供依据。方法 :采用原子吸收分光光度计、原子荧光分光光度计和高效色谱仪对药用白菊花 4个栽培类型重金属与农药残留进行了比较分析。结果与结论 :农药与重金属残留因栽培类型不同而存在明显差异 ,但均符合国家外经贸部颁布的《药用植物及制剂进出口绿色行业标准》(2 0 0 1年 )。

Objective: To study organochlorine pesticide and heavy metal residuals of Chrysanthemum morifolium. Method: The contents of organochlorine pesticide residuals was determined by chromatography, Cu, Pb, Cd was determined by AAS, and As, Hg was determined by AFS. Result and conclusion: The contents of organochlorine pesticide and heavy metals residuals are up to 'Green Trade Standards of Importing & Exporting Medicinal plants & Preprations' (MOFTEC,2001), but the contents are different among four cultivars clearly.
