Abstract
Peels of thirteen (13) ripe mango genotypes were analyzed for total phenolic, total flavonoid, vitamin C, vitamin A contents, and antioxidant activity. Statistical analysis showed that the mango genotypes were significantly different in all the chemical assays performed. The total phenolic content of the genotypes ranged from 3.44-14.59% GAE while total flavonoid content ranged from 0.32 - 2.16% CE. The vitamin A and vitamin C contents of mango peels ranged from 24.66 - 92.01 IU/g and 4.55 - 6.40 mg/g, respectively. The DPPH radical scavenging activity ranged from 88.11 - 92.47%. Correlation analysis also showed that DPPH radical scavenging activity has high positive correlation with total phenolic content (r = 0.69), total flavonoid (r = 0.77) content, and vitamin C (r = 0.57). Using standards, the presence of gallic, vanillic, syringic, and ferulic acids were confirmed in Carabao mango peel by comparison of retention times using High Performance Liquid Chromatography (HPLC). The quantity of these phenolic acids was also calculated with gallic acid and ferulic acid having the highest and lowest concentrations in the peels of all the studied genotypes, respectively. The observation and data collected from this study showed that there was chemical variation in the peels of different mango genotypes that can be a basis for future breeding work. Furthermore, mango peel was can be a good source of phenolic compounds, vitamins and antioxidants which can be utilized as a functional food, and for nutraceutical, pharmaceutical and cosmeceutical purposes.
