What is it about?
Anthocyanin extracts (AEs) from Hibiscus rosa-sinensis (petal) were investigated and compared for in-vitro antioxidant activity. 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 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. Strong correlation between antioxidant capacity with TPC and TAC was observed. Significant correlation between antioxidant capacity and TPC, TFC and TAC ascertained that phenolics and anthocyanins were the major contributors of antioxidant activity. This study emphasized H. rosa-sinensis possessing antioxidant and scavenging activity which may be due to its anthocyanins, phenolics and flavonoids contents

Why is it important?
Anthocyanins are important antioxidant pigments found in plants which can cure and inhibit pathogenesis of several disease including cancer,
Perspectives
Hibiscus plants are used for its ornamental properties around the world. Antioxidant potentials of these plants and plant parts (flower) can be exploited by food and phytochemical industry.
