Study on chemical Constitutents, antioxidant properties and toxicity of Hibiscus rosasinesis flower extract

Abstract

As per literature Hibiscus rosasinesis flower contain Vitamin C and since the flower is red in colour; it may contain anthocyanin. Both these ingredients are good antioxidants and very much essential for proper maintenance of human skin. Hence, the present paper deals with the ascorbic acid and anthocyanin content in Hibiscus rosasinesis Fower; its antioxidant property and toxicity to ensure whether Hibiscus rosasinesis flower extract can be used for topical purpose. The acidified aqueous extract of fresh flowers, contain 0.5% to 1.0% anthocyanin while aqueous extract of fresh flowers contain 0.1% Vitamin C (Ascorbic acid). Vitamin C was estimated by iodometric titration while; Anthocyanin was estimated using UV-Visible Spectrometer. Since both these contents are essential for dermal cells, it can be concluded that Hibiscus rosasinesis flowers can find application in dermal activities like wound healing and anti-ageing. The ethanolic extract of the flowers were found to be non – toxic and exhibit antioxidant activity.
