Total phenolic content (a) and total flavonoid content (b) of the ethanolic extracts from pericarp, aril, and seed of dried (unfilled squares) and black (filled squares) D. longan. The letters (a, b, c, and d) denote significant differences in total phenolic content or total flavonoid content among various D. longan extracts (p < 0.05) when analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post-hoc tests (n = 3).
