中药质量标志物（Q-marker）是中药质量控制研究的新方向之一。Q-marker既可以是质量化学标志物（Q-chemomarker），也可以是质量生物标志物（Q-biomarker）。研究建立良好的Q-biomarker，可以提高中药质量控制方法和标准与临床安全性和有效性的关联度，同时兼顾质量控制的可操作性。当前，我国和美国药品管理部门已将生物评价方法作为中药和植物药质量控制的重要内容。相关企业和研究者也正在积极探索和发展中药质量生物评价方法。在此背景下，从Q-biomarker的角度，进一步丰富和拓展中药质量生物评价的方法和指标，并对相关研究实例进行综述和解析，以期为促进中药Q-marker理论和方法体系的丰富与发展，解决中药质量评控研究中的实际问题提供参考。

Quality marker (Q-marker) is one of the new directions in the research of quality control of Chinese materia medica. The Q-marker can be either quality chemomarker (Q-chemomarker) or quality biomarker (Q-biomarker). The establishment of a good Q-biomarker can improve the linkage of Chinese medicine quality control methods and standards with clinical safety and effectiveness, at the same time considering the operability of quality control. At present, the FDA of China and the United States have adopted biological evaluation methods as an important part of quality control of Chinese medicines and botanicals medicines. Many companies and researchers are also actively exploring and developing methods for the evaluation of quality of Chinese materia medica. This paper further enlarges and expands the methods and indicators of biological evaluation of Chinese materia medica, and summarizes and analyzes relevant research examples from the perspective of Q-biomarker. We hope that it would promote the richness and development of the theoretical system of Chinese medicine quality markers, so as to provide a reference to solve the practical problems for the quality control and evaluation of Chinese materia medica.
