Green Approach Extraction of Perezone from the Roots of (A. Grey): A Comparison of Four Activating Modes and Supercritical Carbon Dioxide.

Perezone, a sesquiterpene quinone, is a very important molecule due to its pharmacological activities in addition to the fact that it is considered to be the first secondary metabolite isolated in the new world (America-Mexico, 1852). This study aims to offer a green comparative study about the extraction of the target molecule from the roots of the vegetable specimen (A. Grey).
