Figure 4
Effect of pH of phenolic compounds (scopoletin, rutin, and quercetin) adsorption in noni juice onto a weak base ion exchange resin (Amberlite IRA 67) at different pH. Graph represents the mean of three replicate samples with error bars. āDifferent letters in the same phenolic compounds indicate significant difference ().
