Abstract

The invention discloses a determination method for an HPLC fingerprint spectrum of a Linaoxin Pian as well as a standard fingerprint spectrum of the Linaoxin Pian. The determination method comprises the following steps: (1) preparing reference solution, namely respectively preparing sodium tanshinol, protocatechualdehyde, puerarin, paeoniflorin, liquiritin, polygonum multiflorum glycoside and salvianolic acid B reference solution; (2) preparing test solution, namely taking the Linaoxin Pian, extracting, and filtering extract with a micropore filter membrane, so that the test solution is obtained; and (3) performing the determination method, namely performing determination by adopting high performance liquid chromatography, wherein chromatographic conditions comprise that a chromatographiccolumn takes octadecyl silane bonded silica gel as filler, gradient elution is adopted, a mobile phase A is 0.01-3% phosphoric acid aqueous solution, a mobile phase B is acetonitrile, flow rate is 0.3-1.5ml / min, column temperature is 20-45 DEG C, and detection wavelength is 230nm.

Description

technical field [0001] The invention relates to a method for analyzing fingerprints of traditional Chinese medicines, in particular to a method for determining HPLC fingerprints of Linaoxin Tablets, and the obtained fingerprints of Linaoxin Tablet preparations. [0002] technical background [0003] Cardiovascular and cerebrovascular diseases are common diseases that seriously endanger human health in recent years. Due to the improvement of human quality of life, cardiovascular and cerebrovascular diseases are on the rise. In the treatment of cardiovascular and cerebrovascular diseases, although the single-target effect of traditional Chinese medicine is weaker than that of Western medicine, the advantages of multi-channel, multi-target, dynamic overall treatment, and less toxic and side effects are far superior to Western medicine, especially the comprehensive treatment of Chinese patent medicines with definite curative effects. The effect is better than western medicine. ...
