Abstract
Background: New findings on the potential of wild mangoes from the island of Sumatra as a source of antioxidant helps their conservation effort as it introduces their useful compounds to the public. This study aims to analyze the antioxidant profile and quantification of gallic acid and quercetin content from leaves and bark of Sumatran wild mangoes. Exploration and analysis of phytochemical constituents from 11 Sumatran wild mangoes was performed. Methods: Antioxidant activity of wild mangoes was analysed with 1,1- diphenyl-2-picryl hydroxyl (DPPH), and determination of quercetin and gallic acid content was performed by high performance liquid chromatography (HPLC) method. Total flavonoid and phenolic analysis was also performed. Curve fitting analysis used a linear regression approach. Results: The highest level of antioxidant activity, phenolic compound and flavonoid compound was found in the leaves and bark of Mangifera sp1. (MBS), the bark of M. foetida3 (var. batu) and leaves of M. torquenda, and the bark and leaves of M. sumatrana, respectively. The content of gallic acid in leaves ranged from 5.23-35.48mg/g dry weight. Quercetin content of wild mangoes leaves ranged from 0.76 to 1.16mg/g dry weight with the lowest value in M. foetida2 (var. manis) and the highest in M. laurina. Conclusion: The results obtained are expected to be useful in supporting the development of drugs that have antidegenerative effects.

New findings on the potential of wild mangoes from the island of Sumatra as a source of antioxidant helps their conservation effort as it introduces their useful compounds to the public
This study aimed to analyze the antioxidant compound of wild mangos from Sumatra, Indonesia in order to preserve its existence in nature
A small amount of natural material is used to evaluate antioxidant activity, so it is widely used to test the ability of compounds that act as electron donors[32]
