The bioactivity and chemical profile of dandelion. a the antioxidant activity represented by radical scavenging rates of dandelion at different concentrations and gallic acid (GA, 1.6 µg/mL); b the anti-inflammatory activity represented by LPS-induced NO production of dandelion and dexamethasone (DXMS, 2 µg/mL) and c their cytotoxicity on RAW 264.7 cells at different concentrations; d antioxidant activity of different dandelion samples at 500 µg/mL; e anti-inflammatory activity of different dandelion samples at 100 µg/mL; f the correlation heatmap of chemicals and active capacity of dandelion samples. DE: dandelion extract. Data is expressed as mean ± SEM of three experiments (n = 3) performed in triplicate, one-way ANOVA, ^####p < 0.0001, LPS (1 µg/mL) vs. control group; ***p < 0.001, ****p < 0.0001, other groups vs. LPS (1 µg/mL)
