Problems solved by technology

Its "Chinese Pharmacopoeia" 2015 edition records that kudzu root is based on puerarin, danshen is based on tanshinone IIA, red peony is based on paeoniflorin, notoginseng is based on notoginsenoside R 1 Astragalus is used as an index, and astragaloside IV is used as an index for Astragalus membranaceus, but when using high-performance liquid chromatography to measure, the contents of astragaloside IV, puerarin, and paeoniflorin are separately measured, and there are few components to be measured. For the quantitative analysis of these three components It is difficult to truly control the product quality of traditional Chinese medicine in detection, and it is impossible to completely eliminate the phenomenon of adulteration and inferiority of traditional Chinese medicine, and it cannot objectively reflect and evaluate the consistency of the quality of traditional Chinese medicine, and the sample pretreatment is cumbersome, the analysis time is long, and the operability is not strong
