Abstract

The invention discloses a method for detecting whether honeysuckle extracts and related products are mixed with honeysuckle vines, which can determine whether the honeysuckle extracts and related products are mixed with honeysuckle vines for feeding. The inspection method comprises the following steps: uniformly mixing and extracting samples to be tested; HPLC chromatographic analysis, including determination of HPLC chromatograms, positioning of chromatographic peaks of target components, and calculation of peak area ratios. The method of the invention has simple operation and simple steps; no organic reagent is used in the preparation process of the test solution and the reference solution, and the analysis cost is low.

Description

technical field [0001] The invention relates to the technical field of quality control of traditional Chinese medicine extracts, in particular to a method for detecting whether the raw materials of honeysuckle extracts and related products are doped with honeysuckle. Background technique [0002] The flowers and stems of Lonicera japonica Thunb. can be used as medicine. The dried flower buds or the first flowers are honeysuckle (harvested before opening in early summer), and the dried stems are honeysuckle vines (harvested in autumn and winter) . Through investigations in medicinal material markets and pharmacies, it was found that the prices of the two differ greatly, and the price of honeysuckle is about 10 times that of honeysuckle. Honeysuckle extract and related products should be fed with honeysuckle, but in order to save costs, some criminals may use honeysuckle vine instead of feeding, or mix part of honeysuckle vine into feeding. [0003] In terms of appearance, h...
