Methods for extracting avocado furan lipid compounds and polyhydroxylated fatty alcohols, compositions and treatments based on the compounds, use of the compounds in beauty and food
The invention concerns a method for selectively extracting furan lipids and polyhydroxylated fatty alcohols of avocado, characterised in that it comprises steps which consist in: preparing an unsaponifiable matter of avocado； then in subjecting the unsaponifiable matter of avocado to a step of molecular distillation using adjusted temperature and pressure means to obtain either a distillate comprising mainly furan lipids and polyhydroxylated fatty alcohols of avocado. Said method enables in particular to extract selectively furan lipids of avocado having a furan lipid content of more than 80 wt. %, even close to 98%.
