Phytochemical analysis and antioxidant activity of Manilkara zapota L. peel

Some fruit peels are widely used to combat oxidative stress because they are known to be abundant in antioxidants. Manilkara zapota L. peel has many nutraceutical phytochemicals, such as polyphenols, carotenoids, sterols, saponins, terpenes, and vitamins, which are what give them their health-promoting qualities. Ascorbic acid, carotenoids, and phenolics are examples of phytochemicals that may directly affect their capacity to scavenge radicals. The current study compares the phytochemicals (total phenols, flavonoids, total sugar, reducing sugar, and non-reducing sugar) and in vitro antioxidant activities in M. zapota peel extracts prepared with methanol and ethyl acetate. A variety of phytochemicals are examined in methanol and ethyl acetate extract of peel, including total phenolic content (29.791 +/- 0.373 and 9.894 +/- 0.326 mg GAE/g), total flavonoids (6.876 +/- 0.200 and 3.352 +/- 0.260 mg CE/g), total sugars (606.188 +/- 0.244 and 139.955 +/- 0.159 mg/g), reducing sugars (343.425 +/- 0.56 and 88.307 +/- 0.290 mg/g), and non-reducing sugars (262.103 +/- 0.221, and 50.847 +/- 0.178 mg/g). The antioxidant activity of methanol and ethyl acetate extract was analyzed via the FRAP assay (10.18 mMFe(II)/ ml and 8.27 mM Fe(II)/ml), total antioxidant capacity (0.54 mg AAE/ml and 0.51 mg AAE/ml), DPPH free radical scavenging activity (IC50 93.782 mu g/ml and 309.005 mu g/ml), and ABTS free radical scavenging activity (IC50 96.52 mu g/ml and 305.07 mu g/ml). These results find that M. zapotais a good source of phytochemicals and minerals with pharmaceutical and good physical condition.
