Fig. 4 in Puerol and pueroside derivatives from Pueraria lobata and their anti-inflammatory activity

Fig. 4. Effects of the tested compounds on the expression of inflammatory factors in LPS-stimulated RAW 264.7 cells. The total RNA was extracted, and Real-time PCR was performed using specific primers to the mRNA expression of TNF-α (A), IL-1β (B) and IL-6 (C). ##P <0.01 and ####P <0.0001, compared to the control group; *P <0.05, **P <0.01, ***P <0.001 and ****P <0.0001, compared to the LPS alone group.
