Problems solved by technology

Thin-layer chromatography was used to determine the content of berberine hydrochloride and the qualitative identification of forsythia and Phellodendron cortex. The developing agent contained benzene and other substances that are highly toxic to the human body, which is not conducive to the health of laboratory personnel. At the same time, forsythia was not tested. As there is honeysuckle in the prescription, and there are differences between honeysuckle and mountain silver flower in terms of medicinal history, plant morphology, medicinal properties, chemical composition, etc., especially mountain silver flower contains a large amount of saponins, there may be hemolysis and other safety risks, laying hidden dangers for clinical use

Embodiment 1

[0060] A kind of compound cortex cortex liquid, its raw material consists of:

[0061] Forsythia 80 parts by weight Cortex Phellodendri 40 parts by weight

[0062] Honeysuckle 40 parts by weight Dandelion 40 parts by weight

[0063] Centipede 2.4 parts by weight.

[0064] A preparation method of compound Phellodendron Phellodendron comprises the following steps:

[0065] (1) Weigh the five traditional Chinese medicines in the prescription according to the weight components, add water to decoct and extract three times, the first time is 1 hour, the second time is 45 minutes, and the third time is 30 minutes;

[0066] (2) Combine the decoctions, filter, and concentrate the filtrate to a clear paste with a relative density of 1.10-1.15 (measured at a temperature of 50°C);

[0067] (3) Add ethanol to make the ethanol content reach 70%, let it stand for 24 hours, filter, and concentrate the filtrate under reduced pressure until there is no ethanol, and obtain the clear liquid fo...

Abstract

The invention discloses preparation and quality detection method of compound prescription cortex phellodendri chinensis fluid. The quality detection method comprises the identification of forsythia fruit, cortex phellodendri, honeysuckle and dandehon herb, the checking of lonicerae flos, and the content determination of forsythin and berberine hydrochloride. According to the determination method, spots with the same colors are formed in a qualified test article thin-layer chromatogram and in corresponding positions of a reference substance thin-layer chromatogram, and negative control is interference-free, and the method is good in selectivity, simple and accurate. The checking method of lonicerae flos adopts a high performance liquid chromatography, is good in specificity, and can distinguish the situation that lonicerae flos is adopted in the compound prescription cortex phellodendri chinensis fluid to pretend honeysuckle flower to charge material. The content determination of forsythin and berberine hydrochloride is good in linear relation and high in recovery test accurancy, has good repeatability and stability, can accurately and strictly detect the quality of the compound prescription cortex phellodendri chinensis fluid, and guarantees a high quality standard level of the compound prescription cortex phellodendri chinensis fluid.
