The invention discloses a cynanchum atratum extract as well as a preparation method and application thereof. The cynanchum atratum extract is an extract obtained by extracting cynanchum atratum with 50-80% ethanol. The cynanchum atratum is a root and a rhizome of a Tylophora yunnanensis Schlechter, which is a plant of the Schlechter family, and the root and the rhizome of the Tylophora yunnanensis Schlechter. Cell experiments and animal experiments prove that the extract obtained by extracting cynanchum atratum with 75% ethanol has the effects of inhibiting breast cancer and hepatoma carcinoma cell proliferation, inducing breast cancer and hepatoma carcinoma cell death and reducing tumor volume and tumor quality, has a remarkable effect on treating liver cancer and breast cancer, and has a practical application value.

The application belongs to the technical field of traditional Chinese medicine detection, and specifically provides a construction method and a quality detection method for characteristic chromatograms of Sarcandra glabra medicinal preparation, wherein octadecylsilane bonded silica gel is used as a filler, acetonitrile is used as mobile phase A, and a water solution containing potassium dihydrogen phosphate is used as mobile phase B, a gradient elution program is continuously optimized, the column temperature is controlled to be 23-27 DEG C, 11 common characteristic peaks are finally obtained, 9 common characteristic peaks are effectively separated, the characteristic chromatogram obtained has a smooth baseline, the characteristic peaks have good peak shapes, and the detection time is short, thereby providing a scientific basis for comprehensively establishing the quality control standard of Sarcandra glabra formula granules. Moreover, the peak positions of tryptophan, syringin, isovanillin and magnoflorine can be accurately positioned, the known information of the characteristic peaks is increased, and the integrity and characteristics of Sarcandra glabra medicinal preparation (for example, formula granules and other preparations) are fully reflected.
