Effect of phlorotannins purified extracts on LPS-induced NO production in RAW 264.7 cells.
Values of each group are expressed as % of LPS-only exposed cells (mean ± SEM of 4 independent assays). *p<0.05, **p<0.01, ***p<0.001.
Figure 4.
Effect of phlorotannins purified extracts on SNP-generated NO in a cell-free system.
Values of each group are expressed as % of control (mean ± SEM of 4 independent assays). *p<0.05, **p<0.01, ***p<0.001.
