Abstract

The invention provides a fingerprint spectrum detection method for a low-sugar intensified loquat distillate, relating to the technical field of drug detection. The fingerprint spectrum detection method comprises the following steps: (1) establishing a component standard characteristic spectrum of the low-sugar intensified loquat distillate; (2) determining a sample characteristic spectrum of a to-be-detected low-sugar intensified loquat distillate by virtue of the same method; and (3) making comparison on the sample characteristic spectrum of the to-be-detected low-sugar intensified loquat distillate and a standard characteristic spectrum of the low-sugar intensified loquat distillate, and judging the quality and authenticity of the low-sugar intensified loquat distillate. The fingerprint spectrum detection method has the beneficial effects that the integrality, the macroscopic characteristic and the fuzziness are realized; the problem that the real adding situation of a product is difficulty reflected by the content determination of a single component is overcome; a novel method and measures are provided for the complete and accurate evaluation of the quality of the low-sugar intensified loquat distillate; the similarity and difference of spectra are visually identified; and the authenticity and quality level of the sample are quantized by virtue of semi-quantitative indexes.

Description

technical field [0001] The invention relates to the technical field of drug detection, in particular to a fingerprint detection method of low-sugar strong loquat dew. Background technique [0002] Low-sugar type strong loquat dew is processed by a certain process from medicinal materials such as loquat leaves, poppy husks, basil, baiqian, mulberry bark, bellflower, and menthol. It has the effects of nourishing yin and astringing the lung, antitussive and expectorant. For chronic cough, labor cough, bronchitis, etc. [0003] As we all know, the efficacy of Chinese patent medicine does not come from any single active ingredient, but the result of the joint action of various effective parts. It is impossible to characterize the quality of the low-sugar strong loquat, and there is a great risk. The fingerprint can more comprehensively characterize the ingredients of the low-sugar strong loquat loquat, and more strictly control the quality of the low-sugar powerful loquat loqu...
