Problems solved by technology

The preparation method of Kudiezizi extract is disclosed, which adopts the method of repeatedly adjusting the acidity and alkalinity of alcohol solution. Since luteolin-7-O-β-D-glucuronide is unstable in alkaline solution, it is prone to oxidation and Ring-opening reaction, and the cichoric acid in Kudiezi is not easy to precipitate in acidic solution, resulting in low yield and loss of a large amount of active ingredients
At the same time, although the patent provides that the content of the extract luteolin 7-O-β-D-glucuronide is only about 8%, this content has neither reached the standard of the second-class raw material drug for intravenous injection, that is, 80% above
[0008] 4. The invention patent of application number 200410078168.0 "a preparation containing the extract of Aphrodisiac clamosa and its preparation method" discloses a composition containing total flavonoids Not less than 80, of which the flavonoid luteolin 7-O-glucuronic acid is not less than 24, and the adenosine is not less than 0.18. Column chromatography, on the one hand, the flocculation process is complicated to operate, the product yield is low, and non-drug impurities are easily brought in; on the other hand, simple water or alcohol-treated extracts are subjected to column chromatography, and the impurity content is large, which affects the separation effect , resulting in heavy production load and low finished product content
Furthermore, this method is not conducive to the extraction of cichoric acid

Abstract

The invention discloses a preparation method, a quality control method and an application of composition of active ingredients ob bitter herb. The composition of the active ingredients of the bitter herb disclosed by the invention mainly comprises cichoric acid and luteolin-7-O-beta-D-glucuronide, and content of the cichoric acid and the luteolin-7-O-beta-D-glucuronide is not less than 80%. An extraction method of the composition comprises that pretreatment is carried out by adopting an enzymatic method, then a supercritical fluid extraction method is adopted, and the obtained extract is respectively subjected to separating, purifying, concentrating and drying by virtue of an AB-8 resin column and a polyamide resin column so as to obtain the composition. Besides, the invention also relates to an application of the composition in preparation of modern bitter herb injection and treatment on coronary heart disease, angor pectoris, myocardial infarction and cerebral infarction and an application of the composition in content determination of the composition of the active ingredients of the bitter herb and quality control of bitter herb medicinal material.
