Abstract
The present invention relates to a sesamol derivative or its salt, and a skin external composition containing the same. More particularly, the invention relates to a sesamol derivative or its salt, which consists of sesamol and 3-aminopropane phosphoric acid, linked with each other by a phosphoric acid diester bond, and can be degraded into sesamol and 3-aminopropane phosphoric acid by enzymes present on the skin so as to simultaneously show the physiological activities of sesamol and 3-aminopropane phosphoric acid, as well as a preparation method thereof and a skin external composition containing the same.
