黄连中重金属及其安全风险评估研究进展

Research Progress and Risk Assessment of Heavy Metal in Coptis chinensis

黄连为多年生中药材,多生长在湿度较大、温度适宜的环境中,是临床上比较常见的处方药,为我国常用大宗药材。近年来,黄连的需求量不断增大,但由于植物生长环境中的重金属残留加剧,影响了黄连的药用价值,甚至危及人类的健康,因此,黄连中重金属超标的问题已引起重视。本文综述了20世纪90年代左右至今黄连的重金属残留的来源、检测技术及危害和重金属安全风险评估等方面的研究成果,并对国内外的重金属残留限量标准进行整理比较,以期为提高黄连用药安全提供参考方案,从而推动我国黄连产业的可持续发展。

Coptis chinensis is a perennial Traditional Chinese Medine, which grows in the environment of high humidity and suitable temperature. It is a common prescription medicine in clinic. In recent years, the demand of Coptis chinensis is increasing, but due to the intensified heavy metal residues in the growing environment of plants, the medicinal value of Coptis chinensis is affected and even endanger human health. Therefore, the problem of excessive heavy metals in Coptis chinensis has attracted everyone’s attention. This paper summarized the research results on the source, detection technology and harm of heavy metal residues in Coptis chinensis from 1990s to now, and arranged and compared the heavy metal residue limit standards at home and abroad were compared, in order to provide a reference scheme for improving the safety of coptis chinensis medicine, so as to promote the sustainable development of China’s Coptis chinensis industry.
