An ultrasonic extraction performance checking device and method for an ultrasonic extractor for detecting and analyzing a chemical composition of a consumer product. The ultrasonic extraction performance checking device includes a hanging frame which is hung inside the ultrasonic extractor and matched with the ultrasonic extractor, and a hanging frame plane checking device which is detachably and vertically or horizontally placed in the hanging frame and clamped with an alloy foil. The alloy foil is surrounded by a tensioning fixture. The tensioning fixture causes the alloy foil to generate a surface tension of 5 to 15 N and to be tightened and fixed to the bottom surface of the hanging frame plane checking device.
