Premature ovarian failure(POF) is a female reproductive system disease caused by many factors and systems,which has seriously affected the quality of life of women of childbearing age.Clinically,the disease is difficult to treat while its incidence rate shows an increasing trend.In recent years,natural products used as multi-pathway,multi-target and efficient drugs,have become the focus of many research and clinical studies in China and abroad,and the effect of phytochemicals derived from edible plants and Chinese medicine herbs on POF were investigated in several papers.Using "premature ovarian failure" or "ovary" and related natural products as keywords,we retrieved and reviewed research articles from China National Knowledge Infrastructure Database,Wanfang,Pub Med,Web of Science and other literature databases.Up to October,2021,natural compounds with prophylactic or interference inhibition effects on POF mainly included flavonoids,polysaccharides,saponins,and polyphenols.Their effect on POF and ovarian function was closely related to their antioxidant,antiapoptotic,antiaging,immunoregulatory and estrogenlike activities.
