Abstract
This study was aimed at investigating the antioxidant property of anthocyanin extracts (AEs) from Hibiscus rosa-sinensis (petal). Preliminary phytochemical studies confirmed the presence of tannins, saponins, alkaloids, steroids, flavonoids and carbohydrates in the extract. Total phenolic content (TPC), total flavonoid content (TFC) and total anthocyanin content (TAC) of the AEs were also determined. In vitro antioxidant activity of the AEs was assessed by nitric oxide (NO) scavenging assay. The AEs demonstrated efficient and dose dependent inhibition of nitric oxide. A strong correlation was observed between antioxidant activity when compared with TPC, TFC and TAC. This confirmed that phenolics, flavonoids and anthocyanins were responsible for the exhibited antioxidant activity. Thus, this study highlighted H. rosa-sinensis having antioxidant properties which may be due to its anthocyanins, phenolics and flavonoids contents.
