Total phenolic in various leaves extracts of four varieties mangoes
The total phenolic contents among the different varieties were expressed in term of gallic acid equivalent using the standard curve equation y = 0.004x + 0.993, R2 = 0.993. The total phenolic content in various leaves extracts of four varieties mangoes showed different result ranged from 6.13 to 30.73 g GAE/100 g. GD2 leaves extract (ethyl acetate leaves extract of gedong mangoe) had the highest phenolic contents (30.73 g GAE/100g) (Fig 4).
