Abstract
The presence of phenolic, flavanoid and tannin compound content in the methanolic extract of Garcinia atroviridis were investigated in this study using UV-Vis Spectrometry and consequently find the relationship between the chemical contents with the antioxidant activity. Garcinia atroviridis has phenolic content the highest followed by flavonoid and tannin content. The antioxidant activities of dried sample of Garcinia atroviridis was carried out by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The plant shows low antioxidant activity. Garcinia leaves from ethyl acetate extract showed the highest antioxidant activity (59.18%) followed by Garcinia leaves from methanol extract (57.97%), and then Garcinia leaves from hexane extract (55.67%). The total phenolic content showed a good correlation with the antioxidant activity but not with the total flavonoid and tannin content.
Highlights
Garcinia atroviridis known as Asam Gelugor is common in the Malay Peninsula
Its fruit is cultivated throughout Southeast Asia for spice
Effect of the extract on DPPH free radical was measured based on DPPH (1,1-diphenyl-2-picrylhydrazyl) assay [10]
Summary
Its fruit is cultivated throughout Southeast Asia for spice. The crude extracts of fruit and leaf of Garcinia atroviridis exhibited significant antifungal activity against Cladosporium herbrum. The root, leaf, trunk and stem bark extracts showed strong antioxidant activity [4]. Various studies have been conducted to investigate the pharmacological activities of Garcinia atroviridis, the chemical investigation to identify the compounds responsible for the precise biological mode of action of this natural product has not yet been reported [6]. This study, was carried out to measure the total content of phenolic, flavonoid and tannin compounds present in the methanolic extract of Garcinia atroviridis and to find the relationship between the chemical contents with the.
