Abstract: Sesamol derivatives or their salts, a process for preparing the same compounds, and a skin external composition containing the same compounds are provided to prevent aging of the biological membrane by slowly releasing sesamol and 3-aminopropan phosphate, and reduce the skin irritation. The sesamol derivatives represented by the formula(I) or their salts are provided, wherein the salt is alkali metal salt or alkali earth metal salt. The process for preparing the sesamol derivatives represented by the formula(I) or their salts comprises the steps of: (A) reacting sesamol with phosphorus oxychloride in the presence of organic base at 12-18 deg. C for 1-2 hours to prepare dichloro[3,4-methylene dioxy penoxy]-phosphino-1-one; (B) reacting the dichloro[3,4-methylene dioxy penoxy]-phosphino-1-one with organic solvent in the presence of base to prepare [3,4-methylene dioxy penoxy]-1,3,2-oxazaphosphorin P-oxide; (C) after filtering the reaction solution and concentrating the filtered solution under reduced pressure, adding the acid solution into the concentrate and reacting them at 5-100 deg. C for 3-12 hours to prepare sesamol(3-aminopropane phosphate diester); and (D) crystallizing the sesamol(3-aminopropane phosphate diester) by slowly dropping polar organic solvent into the sesamol.
