Construction method and detection method for specific chromatogram of areca peel sample

The invention relates to a construction method and a detection method of a specific chromatogram of an areca peel sample, which are characterized in that chromatographic conditions are reasonably controlled through a high performance liquid chromatography detection method, common peaks of the areca peel sample are confirmed, medicinal materials, decoction pieces, standard decoction, standard samples of classic famous prescriptions, preparation intermediates and/or preparation finished products are used as test articles for detection, and the specific chromatogram of the areca peel sample is obtained. And constructing the specific chromatogram of the areca peel sample. The specific chromatogram provided by the invention comprises five characteristic peaks, namely a peak 2, a peak 3, a peak 4 and a peak 5, wherein the peak 2, the peak 3, the peak 4 and the peak 5 are demethylated arecoline, arecoline, demethylated arecoline and arecoline respectively. The method is widely applicable to inspection of various sam
