Abstract

The invention discloses a quality control method of intestine astringe antidiarrheic preparation. The intestine astringe antidiarrheic preparation consists of 7 to 18 parts by weight of featherleaf rodgersflower extract, 700 to 800 parts by weight of bentonite and auxiliary materials with appropriate quantity. The quality control method of the intestine astringe antidiarrheic preparation comprises the following steps of utilizing high-efficient liquid-phase chromatography to determine content of bergenin in the preparation; determining content of aluminum oxide in the intestine astringe antidiarrheic preparation; and determining content of silicon dioxide in the intestine astringe antidiarrheic preparation. The quality control method is characterized in that on the basis of the traditional standard, the main active component bergenin is quantitatively detected, and main active components such as aluminum oxide and silicon dioxide in the preparation are quantitatively detected. The method is operable, simple, feasible and capable of effectively controlling the quality of the intestine astringe antidiarrheic preparation.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine quality, and in particular relates to a quality control method of an astringent intestine antidiarrheal pharmaceutical preparation. Background technique [0002] Astringent intestine antidiarrheal powder currently in circulation in the market is a Chinese patent medicine for treating diarrhea caused by spleen and stomach qi deficiency, acute and chronic enteritis, allergic enteritis, indigestion, intestinal dysfunction, etc. On page 643 of the Internal Medicine Spleen and Stomach Volume of the "Compilation of National Standards of Chinese Patent Medicines", the quality control methods in the quality standards are too simple and not specific, making it difficult to effectively quantitatively control the active ingredients of the preparation. The ultraviolet spectrophotometric method of "petgenin" under its quality standard content determination item is slightly weak in sensitiv...
