The free radical scavenging capability of extracts of Garcinia species using DPPH assay. (a) The activities of various extracts. (b) The activities of different species. The extracts were supplemented with DPPH (dissolved in methanol), then shaken vigorously, and incubated in dark at room temperature for 30 mins. Subsequently, the absorbance was measured at 517 nm using a spectrophotometer. Ascorbic acid was used as a positive control and 0.1 mM DMSO was used as a negative control. The most bioactive extract of each species was chosen to compare with others.
