Mango processing causes huge amount of mango wastes (peel and seed). Development of new value-added product from mango waste not only decreases the environment impact but also increases the profit for mango product factories. In this study, the effect of subcritical water as green technology extraction method on extractability of phenolic substances from mango peel were studied. The effects of pH, ratio of sample to solvent, time and temperature on extractability of phenolic were separately investigated. Finally using surface methodology Box-Behnken design were the effect of process parameters extraction time (20-60 min), ratio of sample to solvent (1:40-1:80 w/v) and temperature (180-220 °C) on extractability of phenolic compound studied. The results of this study have shown that the optimum process condition for phenolic extraction from mango peel were at pH 8, ratio of sample to solvent 1:80 (w/v), 40 min at 220°C. The amount of extracted phenolic at these conditions was 99.69 mg gallic acid equivalents/g dry weight
