AI Technical Summary

Technical Problem

Existing technologies make it difficult to quickly and accurately distinguish between Euphorbia kansui formula granules and vinegar-treated Euphorbia kansui formula granules, as their appearance characteristics are similar and easily confused.

Method used

Thin-layer chromatography (TLC) was used to identify the components by preparing a sample solution, extracting it with ethyl acetate, and then performing TLC analysis using toluene-ethyl acetate-formic acid as the developing solvent. The resolution and fluorescent spot positions of different components on the TLC plate were used for identification.

Benefits of technology

It enables rapid and accurate identification of Euphorbia kansui formula granules and vinegar-treated Euphorbia kansui formula granules. It is easy to operate, highly specific, durable, and can clearly distinguish between the two within a specific ratio range.
