RESUMO
Malignant tumor poses a threat to human health and life. The incidence and fatality rate of malignant tumor have been on the rise. The currently available therapies are radiotherapy and chemotherapy， which cause severe adverse reactions and irreversible damage and thus influence the quality of life of patients. Therefore， it is urgent to find new， safe and effective antitumor drugs. Chinese medicinals are safe with little adverse reactions and long-lasting effect in the treatment of tumor， which have attracted the attention of scholars. Amid the advancement of medical research， more and more anti-tumor components have been extracted from Chinese medicinals. Phellinus is a valuable Chinese medicinal material， and the chemical components mainly include polysaccharides， flavonoids， triterpenes， and polyphenols， which have anti-inflammatory， hypoglycemic， liver-protecting， and anti-tumor effect. The chemical components of Phellinus can inhibit various malignant tumors such as lung cancer， gastric cancer， colon cancer， and melanoma. It exerts the anti-tumor effect by inhibiting proliferation and metastasis of tumor cells， inducing apoptosis and autophagy of the cells， suppressing tumor angiogenesis， and regulating the immunity. In addition， it can enhance efficacy， reduce toxicity， and boost the sensitivity in the radiotherapy and chemotherapy. In this paper， articles were retrieved from China National Knowledge Infrastructure （CNKI）， Web of Science， Pubmed， and Google Scholar with keywords such as "Phellinus， chemical components， and anti-tumor"， and then the chemical components of Phellinus and the anti-tumor mechanisms were summarized. The findings are expected to lays a basis for further development and clinical application of this medicinal.
