Evaluation of Antioxidant Properties and Phenolic Compounds of Different Mango (Mangifera indica L.) Southern Iran

Mango is one of the most important tropical fruits in the world. It has many phenolic compounds, flavonoids, and antioxidants. Therefore, 29 genotypes of native mangoes in different regions of in southern of Iran (Kerman and Hormozgan) were collected and evaluated based on the amount of antioxidant, phenolic and flavonoid compounds in the laboratory of Agricultural Biotechnology Research Institute, University of Zabol in 2017. The results of analysis of variance showed that different mango genotypes and mango collection regions were affected on phenol, flavonoids and antioxidant properties. The most amount of flavonoids (176.65 mg/g of hydro alcoholic extract and 122.15 mg/g of hydro alcoholic extract) belonged to helov and Kn genotypes, respectively. The most phenol (11.232 and 10.664 mg/g of hydro alcoholic extract) belonged to Zapak and Kn genotypes. The most antioxidant properties (55.240 and 50.873 micrograms per milliliter) belonged to helov and kharvst genotypes, respectively. Based on the area where the mangoes were collected, the most amount of flavonoids (76.679 and 65.126 mg/g of hydro alcoholic extract) belonged to the mango genotypes of Jiroft and Rodan. The most phenol (6.4783 and 6.4534 mg/kg of fresh weight) belonged to Rodan and Manojan mango genotypes, respectively. The highest antioxidant properties (43.144 and 42.667 μg/ml) belonged to Rodan and Jiroft mango genotypes, respectively. Among the different concentrations of the extract, the most effective concentration was 64 μg/ml. Overall, the results showed that Mangoes in Rodan and Jiroft area had the highest antioxidant properties and increased their antioxidant properties by increasing the concentration of hydro alcoholic extract.
