Problems solved by technology

This method requires the preparations containing Japonica japonicus or the preparation containing Japonica japonicus raw materials as a control to construct an acute oral inflammation model; there are defects such as complex testing methods, not fast enough testing, high cost, many influencing factors, and large errors
[0006] Although there are reports in the prior art that use the ratio of the content of chlorogenic acid to strychnic acid or the single index of the content of Dipsacus saponin B as the identification basis, the premise of its application must be that the sample for character observation is a single herbal decoction piece. It can be applied, but the identification of mixed medicinal materials or medicinal materials whose properties cannot be observed is limited

Abstract

The invention belongs to the technical field of identification of source varieties of traditional Chinese medicinal materials, and relates to a method for identifying honeysuckle and lonicerae flos byutilizing high performance liquid chromatography and liquid chromatography-mass spectrometry. With the adoption of the method, when the test sample is one or two of honeysuckle or lonicerae flos, theweight percentage of the sessile nux vomica acid and the chlorogenic acid in the dried test sample is detected through high performance liquid chromatography, and the ratio of the weight percentage of the chlorogenic acid to the weight percentage of the sessile nux vomica acid is calculated; the weight percentage of dipsacus asperoside B is detected in the dry test sample through liquid chromatography-mass spectrometry. Each honeysuckle is identified by utilizing the weight percentage ratio of chlorogenic acid to sessile strychnolic acid and the weight percentage of dipsacus asperoside B. Themethod is not limited by test sample properties, can be used for identifying single medicinal materials of honeysuckle and lonicerae flos or a mixture of the honeysuckle and the lonicerae flos, can also be used for identifying the single medicinal materials of the honeysuckle and the lonicerae flos or the mixture of the honeysuckle and the lonicerae flos in Chinese patent medicines, effectively improves the identification accuracy, and provides a true and false identification basis for medicine production, circulation and use.

Description

technical field [0001] The invention belongs to the technical field of identification of source varieties of traditional Chinese medicinal materials, and relates to a method for identifying honeysuckle and mountain silver, in particular to a method for identifying honeysuckle and mountain silver by using high-performance liquid chromatography and liquid chromatography-mass chromatography. Background technique [0002] Honeysuckle and mountain silver flower are listed as two kinds of medicinal materials since the 2005 edition of "Pharmacopoeia of the People's Republic of China". Because the two original plant species are similar and the medicinal materials are similar in appearance and shape, it is difficult to distinguish them. Therefore, the sources of medicinal materials of honeysuckle and mountain silver flower are unclear and the varieties are confused. The phenomenon of pretending to be honeysuckle, but the material basis of the two is quite different, which directly af...
