SQE did not affect the viability of RAW 264.7 macrophages in the co-culture system. RAW 264. 7 cells were seeded in 12 well-plates and treated with various doses of SQE (100, 200, and 400 µg/ml), as well as individually with two bioactive compounds, tricin (1 µM) and P-coumaric acid (PC, 2.4 µM), at concentration equivalent to that contained in 400 µg/ml SQE. After 24 h, each set of cells was stained with trypan blue. Both stained and unstained cells were counted, and the proportion of unstained cells was used to calculate cell viability. One-way ANOVA was applied using Tukey's post-hoc test (α = 0.05). SQE, Sasa quelpaertensis extract; PC, P-coumaric acid.
