Composition for improvement of muscle function containing 3,5-dicaffeoylquinic acid or chrysanthemum extract
The present invention relates to a composition for preventing or treating a muscle disorder, which includes a chrysanthemum extract or 3,5-dicaffeoylquinic acid as an active ingredient, and specifically, it may be used to reduce mRNA expression of atrogin-1 and MuRF1, which are main biomarkers involved in muscle protein degradation and increase mRNA expression of the mTOR protein, which is a main biomarker involved in muscle protein formation, and myogenin and MyoD, which are biomarkers related to muscle differentiation, thereby reducing muscle loss, and thus the chrysanthemum extract or 3,5-dicaffeoylquinic acid can be used in prevention and treatment of a muscle disorder, or improvement in muscle function. In addition, the chrysanthemum extract or 3,5-dicaffeoylquinic acid increases the activity of SIRT1 and PGC-1α, which are the main biomarkers involved in exercise performance, thereby excellently enhancing exercise performance. In addition, the present invention is a natural substance and may be safely used without a side effect, and therefore may be used as a medication, food or a cosmetic.
