Abstract

The invention discloses a method for simultaneously detecting content of seven ingredients in stomach-benefiting capsules. The seven ingredients are ginsenoside Rg1, notoginsenoside R1, aloe-emodin, rhein, rheum emodin, chrysophanol and emodin monomethyl ether. The method comprises the steps of: carrying out ultrasonic extraction on a to-be-detected sample with methyl alcohol; after adding alkaliinto extracting solution to perform a reaction, regulating to pH of 2 to 3 with acid; and finally, extracting with ethyl acetate, and after making up to the volume with methyl alcohol, loading the obtained product onto a high performance liquid chromatographic instrument to carry out detection. According to the invention, the content of seven substances in the stomach-benefiting capsules can be simultaneously detected out, so that quality of a medicine can be more comprehensively represented and controlled, the fake and shoddy phenomena of traditional Chinese medicine are prevented, and the medicine curative effect and medicine use safety are ensured better.
