Characteristic map detection method of powerful gastrodia elata-eucommia ulmoides capsules

The present invention discloses a characteristic map detection method of powerful gastrodia elata-eucommia ulmoides capsules. According to the characteristic map detection method, a test sample solution is prepared, wherein the test sample solution contains the site A of an alkaline condition ethyl acetate extraction sample and the site B of an acidic condition ethyl acetate extraction sample; a reference substance solution is prepared; the test sample solution and the reference substance solution are respectively subjected to chromatographic condition determination; the characteristic maps respectively generated from the data of the sites A and B of the test sample solution are subjected to a precision test, a stability test and a repeatability test; the characteristic map of powerful gastrodia elata-eucommia ulmoides capsules is established, and is subjected to similarity evaluation; and finally the attribution of the chromatographic peak is determined so as to identify the components of the powerful gastrodia elata-eucommia ulmoides capsules. The method of the present invention is accurate and reliable, and can be used for the identification and the quality control of the powerful gastrodia elata-eucommia ulmoides capsules.
