Effect of seven potential active constituents (Isoliquiritigenin, Emodin, Taxifolin, Catalpol, Alisol A, Zingerone, and Schisandrin C) on PPARγ, collagen II, and MMP-13 in IL-1β-treated chondrocytes. (A) The expression of PPARγ in IL-1β-treated chondrocytes by protein capillary electrophoresis; (B) PPARγ (red) was detected by immunofluorescence; (C) Collagen II (red) was detected by immunofluorescence; (D) MMP-13 (red) was detected by immunofluorescence; (E) Quantification analysis of the immunofluorescence of PPARγ, collagen II, and MMP-13. **p < 0.01 compared with the control group; # p < 0.05, ## p < 0.01 compared with the IL-1β group.
