Abstract
The classic method for extracting anthocyanins from plant tissues is the same as for other phenolics: the tissues are soaked and then extracted with a solvent in a process known as Solid Liquid Extraction. Modern approaches to anthocyanins extraction include;Supercritical fluid extraction, Ultrasound-assisted extraction, Pressurized liquid extraction, Microwave-assisted extraction, Ohmic heating-assisted extraction, Precipitation, and Solid phase extraction. The aim of this article is to review the methods used for Anthocyanins extraction from Hibiscus Sabdariffa.The study for the same has been done at Charak’s Pharmacognosy Laboratory, MIT-WPU School of Pharmacy, Pune. Usually, modern methods seem to have an edge againsttraditional methods in extraction procedures. This article discusses these methodsand tries to identify if it is the case in the case of anthocyanins extraction from Hibiscus sabdariffa L.while individually commenting on the method’s advantages or disadvantages too.
Keywords: Anthocyanins, Hibiscus Sabdariffa, Modern methods of extraction, colorant, pigments
