Abstract

The invention discloses a quality control method of raw astragalus membranaceus wasting-thirst capsules. With use of thin-layer chromatography (TLC), rhizoma rehmanniae in the raw astragalus membranaceus wasting-thirst capsules is qualitatively identified, and with combination of ultra performance liquid chromatography (UHPLC), calycosin-7-glucoside, salvianolic acid B, salvianolic acid A, sodium danshensu, rosmarinic acid and protocatechuic aldehyde in the raw astragalus membranaceus wasting-thirst capsules are determined, so that the quality of the raw astragalus membranaceus wasting-thirst capsules can be more scientifically evaluated, the stability of the quality is ensured, the level of the product technology is enhanced, and thus the quality standard of the raw astragalus membranaceus wasting-thirst capsules is comprehensively enhanced by the modern analysis method .

Description

technical field [0001] The invention relates to a quality control method of a traditional Chinese medicine preparation for treating diabetes, belonging to the technical field of medicines. Background technique [0002] Shengqi Xiaoke Capsule is a traditional Chinese medicine compound preparation made of three medicinal flavors of astragalus, rehmannia glutinosa and salvia miltiorrhiza.
