| ABSTRACT Objective: To investigate the effect of Chemical Constituents of Camelllia nitidissima Tuyama from methylene chlo- ride ethyl acetate（JHC）on protection against tumor formation in MMTV-PyMT transgenic mice. Methods: MTT assay was performed to evaluate the growth inhibitory rate of SKBR-3; The MMTV-PyMT transgenic mice model was performed to observe the protection effect in carcinogenesis of JHC in vivo. Results: JHC showed significantly inhibition effect on the proliferation of SKBR-3 and the IC50 419.0±12.87 μg/mL. In transgenic mice model, JHC shows significantly inhibitory effect in tumor formation and development; The average tu- mor number of model group is 5.25 /mice, and the JHC treatment group is 3.75 /mice; The average tumor weight of model group is 0.47g/mice, and the JHC treatment group is 0.24 g/mice. Conclusion: Chemical Constituents of Camelllia nitidissima Tuyamafrom Methylene chloride ethyl acetate can protect against the tumor formation in MMTV-PyMT transgenic mice. |
