Abstract: A method of extracting Polyhydroxylated Fatty Alcohols is disclosed. The method may include: inserting crushed avocado seeds to one or more extraction chambers; flowing supercritical CO2 fluid through the crushed avocado seeds in one or more extraction chambers; and separating from the supercritical CO2 flown through the crushed avocado seeds the Polyhydroxylated Fatty Alcohols extracted and dissolved in the supercritical CO2. The supercritical CO2 fluid may be the only solvent used for dissolving and extracting the Polyhydroxylated Fatty Alcohols.

Abstract: A process of obtaining avocado seed extracts comprising polyhydroxylated fatty alcohols (PFAs), the process comprising crushing raw undried avocado seeds; incubating the crushed avocado seeds; and extracting PFAs from the crushed seeds with an organic solvent.
