Natural antioxidant from hibiscus sabdariffa extract: Assessments on extraction yield, antioxidant capacity and total polyphenol content of different polarities of solvent extracts / Nur Royhaila Mohamad ... [et.al.].
Hibiscus sabdariffa L. (H. sabdariffa, roselle; Malvaceae) has traditionally been used as food, in herbal drinks, hot and cold beverages, as a flavoring agent in the food industry and as herbal medicine. The effect of solvents (hexane, ethyl acetate and ethanol) on extraction yield, antioxidant capa...
