The investigation of LOHAS-oriented biological activity of forest products and their applications Forest has been known to have healing power for mind and body. Our group deals with LOHAS (Life Of Health And Sustainability) oriented biological aspects of forest products and their mode of action. In most cases this involves investigating the biological activity of extractives of mushroom , woods and plant etc, such as anti-androgenic activity, prevention effect of bone loss in calcium deficient ovariectomized rats of mushroom, healing aroma, and melanin biosynthesis inhibitory activity of wood extractives. Our research cover several practical fields such as cosmetics, aroma, functional food, living environment, toiletry etc. 1, Search for biologically active substance from plants. 2, Search for biologically active substance from mushrooms. 3, Studies on the mode of action of bioactive natural substances and their structural criteria. 4, The physiological and psychological effect of aroma (natural volatiles) on human. 5, Development of bioactive substances and extracts for practical use (cosmetics, aroma, functional food, toiletry and living environment.)
