Figure 5 Inhbition of LPS-induced NF-κ.B luciferase (Luc) activity by RUS-C40 (n = 3).
Figure 6 Chromatographic fingerprints of the active fraction RUS-C20 (a) and its three subfractions, RUS-C20A (b), RUS-C20B (c) with insets of UV spectra for two compounds (peak 1 and peak 2), and RUS-C20C (d) with insets of UV spectra of two distinct compound groups (group 1: peaks 3, 4, 5 and 6; group 2: peak 7).
Figure 7 NF-κ.B inhibition by subfractions of RUS-C20 (µg/ml). Vertical lines on the top of bars represent one standard deviation of the mean value from triplicates.
