The present invention relates to an external standard reference system of a type inserted into the coil of a human magnetic resonance imaging equipment, and more specifically, to a system capable of analyzing metabolic components (quantity of metabolites) in a human body without an error and a limited range using an external standard reference analysis method, in order to enhance accuracy of diagnosis by utilizing magnetic resonance spectroscopy of the human magnetic resonance imaging equipment. A system for evaluating performance of magnetic resonance spectroscopy includes an outer container for inserting an RF coil and provided with a plurality of holes; a plurality of inner containers arranged to be inserted into the plurality of holes respectively and capable of being filled with metabolites different from each other in at least a type or a concentration; and a frame for fixing a head of an object arranged inside the outer container.
