近年来，植物提取物得到了广泛的开发与利用，但重金属污染问题已经危及到其安全应用。因此，有效去除植物提取物中的重金属污染成为亟待解决的问题和国内外的研究热点。目前应用较为广泛的重金属脱除技术包括絮凝沉淀法、吸附法、分子筛法等。另外一些新型的技术和材料也逐渐应用于植物提取物重金属脱除，如微生物法、纳米技术、离子/分子印迹技术、仿生材料等。对近年来植物提取物中重金属脱除技术的原理和应用进行综述，对各方法的特点进行归纳总结，并对植物提取物中重金属脱除技术的发展趋势和前景进行展望。

In recent years, plant extracts have been widely developed and used, but the pollution of heavy metals has threatened the safe application of plant extracts. Therefore, effective removal of heavy metal pollution in plant extracts has become an urgent problem to be solved and a research hotspot at home and abroad. At present, the widely used heavy metals removal technologies include flocculent precipitation, adsorption, molecular sieve and so on. Other new technologies and materials are also being applied to the removal of heavy metals from plant extracts, such as microbiological methods, nanotechnology, ion/molecular imprinting techniques, biomimetic materials, etc. This paper reviews the related literature about the principle and application of removal of heavy metals in plant extracts in recent years, summarizes the characteristics of each method, and prospects the development trends and prospects for the future.
