Example Embodiment

[0016] Example 1

[0017] 1) Preparation of honeysuckle extract

[0018] Weigh the honeysuckle, add water to warm it for 2-3 times, filter, concentrate, alcohol precipitation, filter, the filtrate recovers ethanol to no ethanol taste, add 2-6 times the amount of purified water of the paste weight, gently stir, stand still, take it The clear liquid is filtered, the filtrate is concentrated and then alcohol-precipitated again, and the supernatant is filtered and concentrated to obtain the honeysuckle extract.

[0019] Detected by high performance liquid chromatography, it was determined that the extract contained chlorogenic acid 15.22mg / g and luteolin 0.38mg / g.

[0020] 2) Preparation of Forsythia Suspense Extract

[0021] Weigh forsythia, add water to decocting for 3 times, combine the medicinal solution, and the subsequent steps are the same as those after honeysuckle warm soaking to obtain forsythia extract.

[0022] Detected by high performance liquid chromatography, it was det...

Abstract

The invention mainly relates to a Shuanghuanglian liquid preparation and a method for measuring the content thereof. The Shuanghuanglian liquid preparation mainly comprises scutelloside, forsythin, chlorogenic acid, and the like, and the adverse reaction thereof is mainly shown in anaphylactic shock, erubescent skin and exanthemata, etc. The invention provides the Shuanghuanglian liquid preparation containing proper chlorogenic acid, scutelloside, forsythin and other effective components, and not only has ideal therapeutic effect, but also reduces the occurrence of the anaphylactic reaction. The invention also provides the method for measuring the content of the Shuanghuanglian liquid preparation; during the application of the measurement method of the invention, only one moving phase is needed to simultaneously measure the content of the five effective components, i.e. the scutelloside, the forsythin, the chlorogenic acid, luteoloside and wogonin. The method not only obviously improves the measurement efficiency, but also effectively reduces the measurement cost.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and in particular relates to a Shuanghuanglian liquid preparation and a content determination method thereof. Background technique [0002] Shuanghuanglian liquid preparation is extracted and refined from honeysuckle, forsythia and scutellaria baicalensis, and mainly contains baicalin, forsythin, chlorogenic acid, luteolin, wogonin, etc. Modern pharmacological studies have proved that Shuanghuanglian liquid preparation has antibacterial, antiviral, and antipyretic effects. Clinically, it is widely used in the treatment of upper respiratory tract infection, pneumonia, tonsillitis, pharyngitis, etc. caused by viral and bacterial infections. However, with the widespread clinical application of Shuanghuanglian liquid preparations, reports of adverse reactions are common. The adverse reactions of Shuanghuanglian liquid preparation mainly include anaphylactic shock, skin flushing, and ras...
