AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively identify the morphological characteristics of granulated ume plum charcoal formulations, and traditional methods are not applicable, resulting in identification methods that are neither simple nor accurate.

Method used

Thin-layer chromatography was used, with silica gel G thin-layer plates and ethyl acetate-cyclohexane as the developing solvent. The samples were identified by observing the positions of the fluorescent spots in the test and reference medicinal materials solutions under ultraviolet light.

Benefits of technology

This paper presents a simple, stable, precise and easy-to-master method for identifying granules of ume charcoal formulations. It can quickly and accurately identify granules of ume charcoal formulations, avoid the use of toxic reagents, and is adaptable to different temperature and humidity environments.

Abstract

This invention provides a thin-layer chromatography (TLC) identification method for charred plum preparations, comprising: A) dissolving a sample in a solvent to obtain a test solution; the sample being tested is a charred plum preparation; B) dissolving a reference plum material in a solvent to obtain a reference material solution; C) performing TLC detection on the test solution and the reference material solution, using a silica gel G TLC plate and ethyl acetate-cyclohexane as the developing solvent; D) examining under ultraviolet light; if the chromatogram of the test sample shows fluorescent spots of the same color at the corresponding positions as the chromatogram of the reference material, then it is a charred plum preparation granule. The TLC identification method for charred plum preparation granules established in this invention uses the presence of fluorescent spots at corresponding positions in the TLC chromatogram as identification points for rapid and effective identification of charred plum preparation granules.
