Problems solved by technology

In the trial standard of Yiqi Fumai Powder Injection, super-macroporous adsorption resin and acidic alumina mixed resin need to receive a large amount of effluent. Stability, unable to express the true content of the preparation product, due to the cumbersome operation, the detection time of more steps is at least 8 hours, which cannot meet the needs of quality inspection
[0005] As above, in the quality standard of Yiqi Fumai preparation, the determination method of total ginseng glycosides is extracted with ether and water-saturated n-butanol. The experimental operation is cumbersome, time-consuming, and the amount of organic solvent is large, which is extremely harmful to the human body and is difficult to meet industrial production. daily inspection

Abstract

The invention relates to Chinese medicinal injectable powder and a quality control method thereof. The Chinese medicinal injectable powder consists of red ginseng, dwarf lilyturf tuber and Chinese magnoliavine fruit in part by weight, wherein the sum of the main active ingredient content of the injectable powder cannot be lower than 4.0mg / g; and the active ingredients comprise ginsenosides Rf, Rb1, Rb2, Rb3, Rd, Rg3 and F2, and schizandrol A. The quality control method comprises the steps of making quality standards, measuring the content, comparing the content of a sample to be measured with the quality standards, and judging whether the content reaches the preset standards or not so as to control the product quality. The method has the advantages of quickness, accuracy, sensitivity, contribution to industrial production inspection, and capability of effectively controlling the quality of a finished product.

Description

technical field [0001] The invention relates to a traditional Chinese medicine preparation, in particular to a traditional Chinese medicine powder injection preparation and a quality control method thereof. Background technique [0002] The records of Chinese medicine quality control methods in my country are the most comprehensive and earliest in the world. However, due to slow technological updates and backward quality analysis and evaluation methods, the current national quality standards for Chinese medicine are still far from perfect and cannot fully reflect the quality of Chinese medicine. The situation is far from meeting the actual needs of the Chinese medicine industry. In the first part of the Chinese Pharmacopoeia of the 2000 edition, a total of 992 kinds of Chinese medicinal materials and Chinese patent medicine preparations have been recorded, 602 kinds have been identified, and 308 kinds have been assayed; among the 458 kinds of Chinese patent medicine preparati...
