The effect of fraction 3A and 4 component system on enzyme activity of COX-1 (Figure 2a) and COX-2 (Figure 2b) in RAW 264.7 mouse macrophages. Q=0.07 µM quercetin, A= 0.08 µM amentoflavone, CA= 0.2 µM chlorogenic acid, PH= 0.03 µM pseudohypericin. Data is presented as mean COX-1 or COX-2 activity ± standard error (nmol/min/ml). n=4 for each. Quercetin (25 µM) was used as positive control. * p-value < 0.05 as compared to media + LPS + DMSO control. $ significant difference between light-activated and dark treatments.
