Inhibitory activities against the secretion of interleukin-6 (IL-6) (a) and tumor necrosis factor-α (TNF-α) (b) of dexamethasone (DEX), gallic acid (GA), corilagin (CO), ellagic acid (EA), and the ethanolic extracts from pericarp, aril, and seed of dried (unfilled squares) and black (filled squares) D. longan. The final concentration of each sample was 1 µg/mL. The letters (a, b, c, and d) denote significant differences in IL-6 or TNF-α inhibition among various tested samples (p < 0.05) when analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post-hoc tests (n = 3).
