Arbutin inhibits salicin bitterness in the black lemur. Water-soaked apple pieces (control) and β-glucoside-soaked pieces were presented to a subject (n = 1) simultaneously. Acceptance ratios for each β-glucoside and the mixture were calculated (mean ± s.e.m.). Behavioural assays (n = 8, respectively) were performed using each β-glucoside. Significant differences were determined by one-way ANOVA followed by Welch's tests with the BH correction (false discovery rate (FDR) q-value, * < 0.05; ** < 0.01; *** < 0.001).
