    • PROBLEM TO BE SOLVED: To obtain a new triterpene through extraction from mushroom basidiocarp, which has collagenase inhibitory action, thus is useful for treating diseases attributable to collagenase activity sthenia such as arthrosis, bone resorption disorder, periodontosis, corneal ulcer and bullous epidermolysis. SOLUTION: This new triterpene is expressed by the formula, having a molecular formula: C30 H40 O5 and a molecular weight of 484, having inhibitory activity against collagenase as an enzyme involving connective tissue matrix metabolism, therefore being useful for e.g. treating various diseases attributable to collagenase activity sthenia such as arthrosis, bone resorption disorder, periodontosis, corneal ulcer and bullous epidermolysis. This compound is obtained by the following process: the basidiocarp of a kind of mushroom such as Trametes mushroom is lyophilized and then subjected to extraction with 85% ethanol, and the resultant extract liquid is concentrated and then further subjected to extraction with ethyl acetate, and the resultant extract is put to a silica get column and eluted with chloroform-acetone (8:2), and the resultant elute is subjected to high-performance liquid chromatography and purified.

    • PURPOSE: To obtain a hyarulonic acid production promoter containing, as active ingredient, yeast extract, capable of promoting the hyarulonic acid productivity in human skin fibroblast, thus useful for preventing skin aging and treating such diseases as to involve the abnormal decomposition of hyarulonic acid, and safe to the human body. CONSTITUTION: A mixture comprising cetanol, lipophilic monostearic acid glycerin-polyoxyethylene cetyl ether, liquid paraffin, methylpolysiloxane, etc., is first prepared by homogeneously mixing these components at 80 deg.C, and butyl p-oxybenzoate is added to and dissolved in the mixture. Separately, a second mixture comprising sodium N-stearoyl-L-glutamate, dipropylene glycol and water is prepared by homogeneously mixing these components at 80 deg.C, and a yeast extract is added to and dissolved in this mixture. Subsequently, the resultant two solutions are mutually mixed and then cooled to 30 deg.C under through agitation, thus obtaining the objective promoter having the above- mentioned advantages.
