肿瘤的多药耐药性（multidrug resistance，MDR）是导致肿瘤化疗失败的重要原因之一。中药单体成分因其高效低毒、多靶点、价廉等特性已逐渐在逆转肿瘤多药耐药中得到了重视。以肿瘤多药耐药的相关机制为切入点，对近年来中药单体成分在逆转肿瘤多药耐药中的研究进行归纳总结，中药单体成分在逆转肿瘤多药耐药方面具有重要的研究意义。

Multidrug resistance (MDR) is one of the major causes of failure of chemotherapy for tumor. Chinese materia medica (CMM) monomers which can reverse MDR have been paid more and more attention to because of the high efficiency, low toxicity, multiple targets, and low price. This paper made the MDR mechanisms as the breakthrough point and summarized the research on CMM monomers reversing MDR of tumor. The results show that the monomer component of CMM reversing MDR of tumor has important significance.
