  • Publication number: 20250222059
    Abstract: The present disclosure provides use of an effective part extract of Monochasma savatieri in preparation of a drug for treating an inflammatory disease or a tumor. In the present disclosure, an effective part of Monochasma savatieri is separated and purified by various separation and purification methods (including solvent extraction, macroporous resin column chromatography, MCI column separation, and Sephadex LH-20 gel column separation) separately, to obtain the effective part extract of Monochasma savatieri. The effective part extract of Monochasma savatieri is capable of significantly inhibiting secretion of TNF-?, and significantly inhibiting proliferation of breast cancer cells and lung cancer cells, thereby effectively treating the inflammatory disease or the tumor. The present disclosure provides a favorable theoretical basis for finding a drug that can effectively treat the inflammatory disease or the tumor from the Monochasma savatieri, which is of great significance to development of novel drugs.
