Moutan Cortex-in vitro 20231023.xlsx

This study aims to assess the bioaccessibility and health risks of heavy metals in the traditional Chinese medicine, Moutan Cortex. Heavy metals (Cd, Pb, Cu, Cr, Zn, Ni) from Moutan Cortex samples from different regions were measured, and their bioaccessibility in the stomach and intestines was analyzed using the Physiologically Based Extraction Test (PBET) model.本研究旨在评估中药材牡丹皮（Moutan Cortex）中重金属的生物可及性（bioaccessibility）及其健康风险。采集不同产地的牡丹皮样品，对其中的重金属（Cd、Pb、Cu、Cr、Zn、Ni）进行含量测定，并采用生理基础提取试验（Physiologically Based Extraction Test, PBET）模型分析其在胃、肠环境中的生物可及性。
