Pharmaceutical or cosmetic composition containing as the active component 1,8-dihydroxy-10-phenyl-9-anthrone, and a process for preparing said active component.
The invention concerns the use of at least an oil derived from the seeds of the gourd family selected from the group consisting of Lagenaria, Luffa and Momordica, for preparing a composition designed to inhibit 5.alpha.-reductase activity, and the use of said oil for preparing a composition for treating prostatic hypertrophy, prostatic adenoma, acne, hyperseborrhea, alopecia, and hirsutism. The invention also concerns cosmetic treatment methods, in particular for greasy skin. The invention further concerns the use of at least an oil derived from seeds of the gourd family in a nutritional food composition for humans and/or animals as additive for inhibiting 5.alpha. reductase activity.
Therapeutic compositions comprising 1,8-dihyroxy-9(10H) anthracenones substituted at position 10 thereof with phenylalkylidene or arylacyl blocking moieties, said compounds having substantial therapeutic activity and minimal inflammatory effect.

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.
