Mono, di and tri-esters of 1,8-dihydroxy-10-phenyl-9-anthrone or -9-anthranol have the formula ##STR1## wherein p is 0 or 1, (a) when p=0, t=1 and R.sub.2 represents hydrogen or --COR.sub.3, (b) when p=1, t=0 and R.sub.1 and R.sub.2 each independently represent hydrogen or --COR.sub.3, R.sub.3 represents linear or branched alkyl having 1-17 carbon atoms, cycloalkyl, phenyl or phenyl substituted by lower alkyl, lower alkoxy, halogen, a nitro function, --CF.sub.3 or a hydroxyl function, and mixtures of said esters. These esters are prepared by reacting 1,8-dihydroxy-10-phenyl-9-anthrone with an activated form of an acid. The esters are useful in human or veterinary medicine and in cosmetic compositions.
1,8-二羟基-10-苯基-9-蒽酮或9-蒽醇的单酯、二酯和三酯的化学式为##STR1##其中p为0或1,(a)当p=0,t=1且R.sub.2代表氢或--COR.sub.3,(b)当p=1,t=0且R.sub.1和R.sub.2各自独立代表氢或--COR.sub.3,R.sub.3代表1-17个碳原子的线性或支链烷基、环烷基、苯基或被低烷基、低烷氧基、卤素、硝基、--CF.sub.3或羟基取代的苯基,并且这些酯的混合物。这些酯是通过将1,8-二羟基-10-苯基-9-蒽酮与酸的活化形式反应制备而成。这些酯在人类或兽医学以及化妆品组合物中有用。
