Embodiment Construction

[0039] Selection of detection wavelength

[0040] There are currently known and reference components in the strong loquat dew, such as morphine, codeine phosphate, papaverine hydrochloride, protobathine, and paraphylline. Considering that the maximum absorption wavelengths of these components should be selected as far as possible, the spectra at 210nm, 237nm, 245nm, 254nm, 286nm, 300nm, and 330nm respectively are used for comparison. Finally, the wavelength of 254nm is determined as the detection wavelength, and at this wavelength The chromatographic peaks are more and easy to identify, and the baseline is relatively flat. See Figure 1-1 to Figure 1-7 .

[0041] Choice of mobile phase system

[0042] The strong loquat dew contains seven medicinal materials with complex components and great differences in polarity. It is necessary to apply a gradient separation method to make most of the components of various properties get better separation. ACQUITYUPLCBEHC 18 (2.1×100mm, ...

Abstract

The invention provides a detection method of fingerprint spectrums of sugar-free strong pipa syrup. The fingerprint spectrums of various ingredients in the sugar-free strong pipa syrup are detected and obtained. The sugar-free strong pipa syrup standard spectrums obtained through the method can provide a reliable basis for identifying the sugar-free strong pipa syrup and controlling quality.

Description

technical field [0001] The invention provides a fingerprint detection method of sugar-free strong loquat dew, belonging to the technical field of medicine. Background technique [0002] Strong loquat dew is a commonly used Chinese patent medicine. It is composed of 7 traditional Chinese medicines: loquat leaf, Baibu, Baiqian, menthol, poppy shell, mulberry white peel, and Platycodon grandiflorum. Chronic cough, bronchitis, etc. [0003] 1. Loquat leaf is a commonly used traditional Chinese medicine. Its taste is bitter, slightly acrid, and slightly cold in nature. Returning to the lung and stomach meridians, it has been used as a medicinal material since ancient times. It is a traditional Chinese medicine for relieving cough and asthma. It has the functions of dissolving phlegm and relieving cough, reducing the stomach’s inversion, relieving dysentery and diuresis. It is effective for neuralgia, arthritis, back pain and cancer. There is also a certain curative effect. It ...
