Antioxidant and Antimicrobial Activities of the Extracts from Different Garcinia Species

Figure 2

The hydroxyl radical scavenging capability of extracts of different Garcinia species. The extracts were supplemented with FeSO₄.7H₂O, salicylic acid, and H₂O_2, followed by being mixed and incubated at 37°C for 30 mins before applied onto a spectrophotometer to measure the absorbance at 562 nm. Ascorbic acid was used as a positive control and 0.1 mM DMSO was used as a negative control.
