Process for the extraction of an active principle from leaves of Olea Europaea to promote the synthesis of stress proteins, obtained active principle

摘要

The object of the invention is a process for the extraction of an active principle for improvement for the production of stress proteins particularly to guard against the effect of ultraviolet radiation, characterized in that it comprises the following steps: ;solubilization of powder of dried olive leaves (Olea Europaea) in water for 2 hours at 60 C., ;decantation, and ;filtration to separate the active phase, concentration, and ;sterilizing filtration on a membrane so as to limit the presence of microorganisms, of total mesophilic flora, of yeast, and of molds. ;The invention also covers a cosmetic composition and a process for improving the production of stress proteins.
