Fig. 1From: Siegesbeckia pubescens Makino inhibits Pam3CSK4-induced inflammation in RAW 264.7 macrophages through suppressing TLR1/TLR2-mediated NF-κB activationHPLC chromatograms of (a) mixed standards (7.5 μg/mL of rutin, kirenol and darutoside) and (b) SPE (1 mg/mL). 1: rutin; 2: kirenol; 3: darutoside. The contents of rutin, kirenol and darutoside were determined to be 0.27 ± 0.01, 1.81 ± 0.02 and 0.28 ± 0.03%, respectively (n = 3)Back to article page
