Abstract: The present study was designed to evaluate phytochemical properties of mango after formalin (37% formaldehyde solution) treatment. For this purpose fresh raw mangoes are collected, washed with pure water and divided into two groups. One group was treated with formalin for 7 consecutive days and another group was kept as normal. Both group of sample are then peeled off, dried, crushed into coarse powder and extracted by ethanol under sonication bath. Then the samples are filtered and concentrated with a rotary evaporator under reduced pressure at 50 °C. Then phytochemical screening was carried out and found that treatment with formalin markedly decreased phenolic and flavonoid content of mango. Similar result was found in both peel and fleshes which indicates that formalin may penetrated into the peel and brings certain change in flesh. Protein content of mango also shows a downward movement after formalin treatment.
