Problems solved by technology

[0005] The applicant of the present invention applied for a patent on September 12, 2002 called a preparation method of total flavonoids preparation of dragon's blood and its quality control method. The patent application number is: 02129687.1. This patent provides dragon's blood The quality control method of the total flavonoid preparation includes carrying out thin-layer identification of ascarin B, determining the content of ascarin B and 7,4′-dihydroxyflavone by spectrophotometry, and using high-performance liquid chromatography for 7,4′-dihydroxyflavone. 4'-dihydroxyflavone is assayed. These methods can carry out quality control to Longxuetong pharmaceutical preparations, but the items detected are less, and the accuracy of thin-layer identification and spectrophotometry is not good enough. The present invention is based on the prior art. On the basis of this method, the content determination of total phenols is added, and the method of using relatively accurate high performance liquid chromatography to determine the content of dragon's blood B is added. Not only that, the present invention also provides a method for the dissolution rate of Longxuetong pharmaceutical preparations. In addition, the present invention also provides the standard fingerprint of Longxuetong medicinal preparation and the application method of the diagram, which can more effectively control the quality of Longxuetong medicinal preparation

Abstract

The invention provides a quality control method for pharmaceutic preparation containing sanguis draconis extract, which can adopt any one or more of the four quality control methods: (1) adopting an ultraviolet-visible spectrophotometry to measure the content of 7,4'-dyhydroxyl flavone; (2) adopting a high performance liquid chromatography to measure the content of lourerin B; (3) adopting the high performance liquid chromatography to detect finger-print; and (4) adopting the high performance liquid chromatography to detect dissolution by combining with a dissolution measurement method. The quality control method provided by the invention has good accuracy, precision and stability, and can effectively control the quality of pharmaceutic preparation containing the sanguis draconis extract.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine analysis, and relates to a quality control method of a pharmaceutical preparation containing extracts of Chinese medicinal materials, in particular to a method for quality control of pharmaceutical preparations containing extracts of dragon's blood. technical background [0002] Dracaena is the resin obtained by extracting the fat-containing wood of Dranaena cochinchinensis (Lour.) S.C.Chen. Mainly produced in Guangxi and Yunnan. According to "Compendium of Materia Medica", it is warm in nature, flat, sweet, salty, non-toxic, enters the blood system, and returns to the three meridians of lung, spleen, and kidney. Muscle sores and other significant effects. Modern medical research has confirmed that dragon's blood can improve the body's microcirculation, adjust the body's metabolism, and improve the body's immune function. [0003] The prescription of the pharmaceutical preparation co...
