The invention relates to compositions intended for external topical use comprising a true solution containing a chromane or chromene derivative having formula (I), preferably a flavonoid, dissolved in a suitable solvent. The invention also relates to a method for preparing such compositions and the use of said compositions as sun protection agents for the skin, advantageously as agents having an anti-erythemal, anti-oxidant, anti-radical, anti-inflammatory or vasculotropic activity. 

Topical solution containing a chromane or chromene derivative

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%.
