Abstract: The present invention discloses applications of extracts from Morus alba L. Disclosed by the present invention is a use of extracts from Morus alba L. in the preparation of a product for alleviating, preventing and/or treating a hepatobiliary disease. The present invention demonstrated experimentally that extracts from Morus alba L. have effects of reducing hepatic lipid content and alleviating hepatic fibrosis in NAFLD mice gavaged with extracts from Morus alba L., thereby alleviating high-fat diet-induced fatty liver without toxic and side effects on liver and kidney. The drug of the present invention exerts multi-target pharmacological effects through multi-components, and specifically can regulate the hepatic lipid content by regulating the synthesis and oxidation of fatty acids, and can also affect hepatic fibrosis, which is more conducive to the treatment of a non-alcoholic fatty liver disease.
