Problems solved by technology

There are two types of methods for the quality control of Erwuwei Pearl Pills. The first type is that the Pharmacopoeia uses thin layer chromatography to compare with bile acid and pearl reference substances to identify them. The second type is mainly to determine the content of bile acid, western The contents of safflower Ⅰ, cinnamic aldehyde, coynelide, dehydrocoynelide and heavy metal elements provide the basis for its quality control, but there is a lack of methods for its overall quality control

Embodiment 1

[0046] Take 20 twenty-five-flavored pearl pellets produced by a certain company, grind them into powder with an agate mortar, mix well, accurately weigh 0.100g of the powder into a microwave digestion tank, add 10mL of nitric acid and 5mL of hydrofluoric acid in sequence, and heat at 150°C , Digest at 200Psi for 30min, take it out after cooling, wash it in a platinum dish, add 2mL perchloric acid, heat and smoke until it is nearly dry, add 1.25mL hydrochloric acid, and set the volume to 25mL for ICP-AES measurement, and do a blank test at the same time. ICP-AES measurement conditions: peristaltic pump speed 1.30mL / min, incident frequency 1150W, spray chamber pressure 25.0Psi, auxiliary gas 0.5L / min, cooling gas 10L / min, short-wave integration time 10s, long-wave integration time 5s, measurement spectrum wire (Al: 394.401 nm, Ca: 315.887 nm, Fe: 259.940 nm, K: 766.491 nm, Mg: 285.231 nm, Na: 588.995 nm).

[0047] The measured contents of Al, Ca, Fe, K, Mg, and Na in the sample ...

Abstract

The invention relates to a quality control method for traditional Chinese medicines and especially relates to a method for controlling overall quality of a 25-flavor pearl pill. The method comprises the following steps: qualitatively analyzing primary mineral elements contained in the 25-flavor pearl pill; quantitatively analyzing the end product and single medicinal materials for the confirmed primary mineral elements; performing tracing analysis on the primary mineral elements; and formulating a confidence interval of the 25-flavor pearl pill and judging the quality of the primary mineral elements. The invention has the advantages that (1) the method provided by the invention has integrality, macroscopic characteristics and fuzziness and can overcome the defect of difficulty in reflecting the overall content by the single component content determination; (2) the invention provides a new method and way for completely and accurately evaluating the overall quality of the 25-flavor pearl pill; (3) the confidence interval of each mineral element is used for evaluating the quality of the 25-flavor pearl pill, the method is reliable and the efficiency is high.

Description

technical field [0001] The invention relates to a quality control method of traditional Chinese medicines, in particular to an overall quality control method of twenty-five flavor pearl pills. Background technique [0002] Twenty-five flavor pearl pills, fragrant, bitter and pungent, have the effect of calming the nerves and resuscitation, and are used for hemiplegia, crooked mouth and eyes, unconsciousness, confusion, and delirium. The 2015 edition of the Pharmacopoeia of the People's Republic of China discloses its preparation method on page 433. Twenty-five flavor pearl pills are made of 27 medicinal materials such as pearl, nutmeg, travertine, saffron, woody, etc., which are developed into powder and dried with water. of pills. There are two types of methods for quality control of Erwuwei Pearl Pills. The first type is to compare the pharmacopoeia with thin-layer chromatography and cholic acid and pearl reference substances to identify them. The second type is mainly to...
