Inhibition of inflammatory mediator and ROS production by Sasa albomarginata extract in RAW264.7 cells. (a) Effect on cell viability. (b) Inhibition of NO production. (c) Inhibition of IL-6 production. (d), (e) Inhibition of LPS-induced ROS production. ROS was measured by the fluorescent intensity (d) or counting the fluorescent cells (e). The cells were stimulated with 100 ng/ml LPS with or without the extract. (f) In vitro antioxidant activity. In vitro antioxidant activity of Sasa albomarginata extract was evaluated by the DPPH radical-scavenging assay. Trolox concentration used was 80 µg/ml.
