Establishment method of fingerprint spectrum of beverage capable of nourishing yin, clearing away lung-heat and relieving cough and standard fingerprint spectrum of beverage

The invention relates to a method for establishing a fingerprint spectrum of a beverage capable of nourishing yin, clearing away lung-heat and relieving cough, relates to the technical field of food and drug quality control, and aims to provide a comprehensive detection method for a beverage capable of nourishing yin, clearing away lung-heat and relieving cough with complex components through a unique treatment process and a quality detection method so as to improve the quality control level of a traditional Chinese medicine beverage. According to the present invention, the traditional Chinese medicine beverage fingerprint spectrum establishment method is introduced, the determination wavelength, the mobile phase elution program, the flow rate, the column temperature and the sample size are screened and optimized to obtain the good separation degree, the stable base line and the no negative absorption chromatographic peak, the similarity of each fingerprint spectrum is more than 0.99 through the comparison an
