Abstract

The invention relates to the technical field of chromatographic analysis and particularly to a detecting method of hyoscyamine and hyoscine. In the detecting method, HPLC chromatographic analysis is adopted, and the chromatographic conditions are that the chromatographic column is C18 chromatographic column, the flowing phase A is acetonitrile and the flowing phase B is a mixed solution of phosphoric acid and triethylamine. The mass concentration of the phosphoric acid is 0.09-0.11%, the volume concentration of the triethylamine is 0.015-0.025%, the gradient elution sequence is as follows: 0-35 min for the 6% flowing phase A, 35-40 min for the 6%-30% flowing phase A and 40-50 min for the 30%-6% moving phase A; the flowing speed of the flowing phase is 0.9-1.1 mL/min; the detecting wavelength is 210 nm; and the column temperature of the chromatographic column is 34-36 DEG C. The detecting method provided by the invention can detect the peak of the hyoscyamine and the peak of the hyoscine; the peak appearing time is appropriate and the peaks can be well separated from impurity peaks.

Description

technical field [0001] The invention relates to the technical field of chromatographic analysis, in particular to a detection method for scopolamine and scopolamine. Background technique [0002] Hyoscyamine, also known as hyoscine, is one of the belladonna alkaloids isolated from the traditional Chinese medicine Tianxianzi and Dajinhua. Hyoscyamine has the function of relieving pain and spasm, and has a good effect on sciatica. Sometimes it is also used to treat epilepsy and seasickness. [0003] Scopolamine, which is more toxic than anthrax and can be fatal in a slight overdose, is a tropane-type alkaloid that exists in plants of the nightshade family. Scopolamine is an alkaloid with the strongest pharmacological effect in belladonna, which can be used to block parasympathetic nerves, and can also be used as a central nervous system inhibitor. Its hydrobromide is generally used clinically, which can be used for anesthesia, analgesia, It relieves cough and asthma, is effe...
