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. foetida 3 (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 5.23-35.48 mg/g dry weight. Quercetin content of wild mangoes leaves ranged from 0.76 to 1.16 mg/g dry weight with the lowest value in M. foetida 2 (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.

The content of gallic acid in leaves ranged from 5.2270-35.4763 mg/g dry weight. Quercetin content of wild mangoes leaves ranged from 0.76 to 1.47 mg/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 antidegenerative drugs from natural ingredients that have potential as immunomodulatory agents.
The development of medicine requires preclinical testing of experimental animals. One of the potential plants to be developed as a new medicinal source is Sumatran wild mangoes (Mangifera spp.) which are known to have immunomodulatory activity and higher antioxidant value than cultivated Mangifera. This study was aimed to test the sub-chronic toxicity of the extract of 6 wild mango species on white rats' kidney function. This study used 21 treatments and 3 replications, consisted of 3 control treatments (control 0, with distilled water, positive control (stimuno) and negative control (CMC-Na 1%), and 6 types of Mangifera spp. (Mangifera sp.2 (Hutan), M. sumatrana, M. foetida (var. Batu, Limus, and Manis), and M. laurina) with 3 different dosages. Observations were made macroscopically (morphology) and histology through the glomerulus image to see the percentage of damage. The percentage of glomerulus damage was analyzed by ANOVA and Duncan's test. Based on the results showed that the kidney morphology looked like a pea with brownish-red color and the capsule looked flat (healthy) after being treated. Histologically, the administration of wild mango extract did not cause damage to the rats' kidneys, which was indicated by the glomerulus which was still covered by the bowman capsule and the boundary between the pars visceral epithelium and pars parietal epithelium was clearly visible.
Mangifera foetida L. (Macang) is the type of mangoes that contains the highest levels of mangiferin which has activity of antioxidant, analgesic, anti-drip, anti-inflammatory, antitumor, immunomodulatory and anti-HIV. The potential of Macang as a drug needs to be assessed through phytochemical studies to obtain information on the diversity of Macang secondary metabolite content that is potential to be developed. The purpose of this study was to reveal the diversity of total secondary metabolite compounds contained in Macang with three varieties (Limus, Batu and Manis) using LC-MS analysis. Sampling was carried out use survey method at Remban and Lesung Batu, Kecamatan Rawas Ulu, Kabupaten Musi Rawas Utara, South Sumatra Province. The chromatogram was analyzed using the MassLynx program to obtain the compounds contained in the sample. Names determination of compounds based on Chemspider database and compound classes based on PubChem. The number of metabolite compounds that become characteristic of three Macang varieties in this study was 667 compounds. Limus has a specific compound of 191 compounds, Batu of 162 compounds, and Manis has a specific compound of 202 compounds. The metabolites found in this study are expected to be useful in phytopharmaca and support Macang conservation efforts that rarely found.
