Compositions inhibiting a decrease in bone weight and a decrease in bone salt content in disuse muscle atrophy

摘要

Compositions containing as the active ingredient polyphenols separated and purified from a fruit (for example, a fruit of iRosaceae/i) have an effect of inhibiting muscle atrophy (in particular, disuse muscle atrophy) of mammals. These compositions are also useful in inhibiting a decrease in bone weight and a decrease in bone salt content in disuse muscle atrophy.
