Premature ovarian failure （POF） is a common gynecological endocrine disease ，which can cause follicular development stagnation or premature failure in the ovary ，leading to ovarian function loss ，and seriously affecting women ’s physical and mental health . Traditional Chinese medicine shows less toxicity and side effects but significant effect in the treatment of POF . Chinese herb monomers are the active ingredients of traditional Chinese medicine that exert their effects ，and their chemical structure are determined . From the perspective of Chinese herb monomers ，the author reviewed the mechanism of their effect on improving POF . The results showed that icariin ，quercetin，resveratrol and ginsenoside Rg 1 could improve the ovarian function of POF model animals by activating the phosphatidylinositol 3-kinase/protein kinase B signaling pathway ，inhibiting oxidative stress and apoptosis of granulosa cells ，promoting ovarian autophagy ，and regulating the level of sex hormones ；puerarin and resveratrol can improve the ovarian function of POF model by interfering with Wnt/ β-catenin signaling pathway ，reducing oxidative stress response ，and inhibiting follicular atresia . Although the Chinese herb monomers have certain effect in improving POF，most of them remain in the experimental stage ，and the clinical efficacy in improving POF cannot be objectively evaluated . In the future ，the development of new dosage forms of Chinese herb monomers should be strengthened to lay a foundation for the development of new drugs for treating POF .
