  1. The results are expressed as mean ± SEM (n = 4). Statistical analysis was performed using one-way ANOVA followed by LSD post-hoc test. Significant differences within each column are indicated by different letters (p < 0.05). Dexamethasone (1 µg/mL) showed 99.4 ± 3.8% inhibition of NO, 87.3 ± 8.7% inhibition of TNF-α, and 96.2 ± 1.9% inhibition of IL-1β. NO: nitric oxide, TNF-α: tumor necrosis factor-α, IL-1β: interleukin-1β, compound D: (E)-1-(3,4-dimethoxyphenyl)but-3-en-1-ol, compound D acetate: (E)-1-(3,4-dimethoxyphenyl)but-3-en-1-yl acetate, DMPBD: (E)-(3,4-dimethoxyphenyl)butadiene, PE: phenylbutenoid extract
