朱砂作为许多传统中药的有效成分,在我国已有数千年的应用历史.然而,这些中药中超标的汞含量已成为近年来中药出口的最大壁垒.研究中药中汞的赋存形态及不同形态的毒性效应和生物有效性,有助于辩证地理解中药中汞含量与毒性效应的关系,为科学地制定中药中汞的限量标准提供有力的依据. Cinnabar, as the active ingredient of many traditional Chinese medicines, has been used for thousands of years in our country.However, the excessive mercury content in these traditional Chinese medicines has become the biggest barrier to the export of Chinese medicine in recent years.Studies on the occurrence of mercury and the toxicity of different forms Effect and bioavailability help to understand dialectically the relationship between mercury content and toxic effect in traditional Chinese medicine and provide a strong basis for scientifically setting the limit of mercury in traditional Chinese medicine.
