ABSTRACT
Averrhoa bilimbi L. has various beneficial properties including antidiabetic and antioxidant activity. The effect of traditional sun drying on the stability of fresh A. bilimbi fruits was investigated by using different methanol/water extracts, and their total phenolic content (TPC) and total antioxidant capacity (TAC) compared. The TAC was evaluated using established in vitro models such as 1,1,diphenyl-2-picryl hydrazyl radical scavenging activity, 2,2´-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) scavenging assay, total reducing power, phosphomolybdenum assay and metal chelating activity. All the extracts of the dried fruit showed lower TPC compared to the fresh bilimbi extracts by 23-88%, TAC of which corresponded accordingly. The investigation revealed that A. bilimbi was a good source of antioxidants; however, the drying process of the fruit significantly affected the bioactive compounds.
