The invention provides a construction method and a quality detection method of a characteristic spectrum of a
traditional Chinese medicine composition, and the construction method of the characteristic spectrum comprises the following steps: taking a solution of a
traditional Chinese medicine composition
test sample and a solution of a reference substance, and carrying out
high performance liquid chromatography detection to obtain the characteristic spectrum of the
traditional Chinese medicine composition; wherein the traditional Chinese
medicine composition comprises radix scutellariae, cortex mori radicis, fructus trichosanthis,
semen armeniacae amarae, radix adenophorae,
radix ophiopogonis,
semen coicis,
semen benincasae, fructus aurantii, radix curcumae, rhizoma imperatae, radix salviae miltiorrhizae,
indigo naturalis and clam shells; the liquid chromatographic analysis conditions of the detection are as follows: octadecylsilane chemically bonded silica is used as a filler,
acetonitrile is used as a mobile phase A, a
phosphoric acid solution with the
volume percentage of 0.09-0.11% is used as a mobile phase B,
gradient elution is performed, the detection
wavelength is 207-286nm, the
column temperature is 25-35 DEG C, and the flow velocity is 0.9-1.1 mL / min. The specific chromatogram constructed by the invention can objectively evaluate the quality of a traditional Chinese
medicine composition sample and improve the quality of the traditional Chinese
medicine composition, so that the
curative effect is ensured.
