Method for constructing specific chromatogram of rhizoma acori graminei, and method for identifying rhizoma acori graminei and

The invention relates to the technical field of traditional Chinese medicine identification, in particular to a construction method of a specific chromatogram of rhizoma acori graminei and an identification method of the rhizoma acori graminei. The construction method of the specific chromatogram of the rhizoma acori graminei comprises the following steps: taking a rhizoma acori graminei test sample, adding water, extracting to obtain an extracting solution, and extracting the extracting solution by using petroleum ether to prepare a test sample solution; carrying out liquid chromatogram detection on the test solution, and constructing a specific chromatogram of the rhizoma acori graminei according to a detected liquid chromatogram; the liquid chromatography detection conditions comprise that octadecylsilane chemically bonded silica is used as a filler, a mixed solution of methanol and acetonitrile is used as a mobile phase A, and water is used as a mobile phase B for gradient elution. According to the constr
