The Response Surface Optimization of Supercritical CO Modified with Ethanol Extraction of -Anisic Acid from Flowers and Mathematical Modeling of the Mass Transfer.

A widely disseminated native species from Australia, , which is mainly cultivated in Brazil and South Africa, represents a rich source of natural tannins used in the tanning process. Many flowers of the species are used as sources of compounds of interest for the cosmetic industry, such as phenolic compounds. In this study, supercritical fluid extraction was used to obtain non-volatile compounds from flowers for the first time.
