The Effect of Pluchea indica (L.) Less. Tea on Adipogenesis in 3T3-L1 Adipocytes and Lipase Activity

Figure 7

PCA analysis of FTIR spectral ranges 3000-2800 cm−1 and 1800-950 cm−1 giving PCA score plot (a) and PCA loading plot (b). The 2D PCA score plots showed the clustering separation spectra between groups. DIF = differentiate 3T3-L1 adipocytes (untreated adipocytes); PIT(750) = PIT at 750 μg mL−1 treated adipocytes; SIM(1.67) = Simvastatin at 1.67 μg mL−1 treated adipocytes; ND = 3T3-L1 preadipocytes (nondifferentiated cells) at day 10 after differentiation. The biomarker differences over a spectral range of samples are identified by PC1 and PC2 loading plots.
