Abstract

The invention relates to the field of traditional Chinese medicine, in particular to compound herba houttuyniae syrup, pharmaceutical application thereof in treatment of encephalomyelitis and a detection method. The compound herba houttuyniae syrup is prepared from the following raw materials in parts by weight: 100 parts of herba houttuyniae, 25 parts of radix scutellariae, 25 parts of radix isatidis, 10 parts of fructus forsythiae and 10 parts of lonicera japonica. A preparation method of the syrup comprises the following steps: preparing herba houttuyniae, radix scutellariae, radix isatidis, fructus forsythiae and lonicera japonica, adding water in an amount which is 7 times that of the raw materials for decocting twice for 2 hours, combining decoction solutions, filtering, concentrating filtrate into clear paste, adding ethanol till the alcohol content is up to 70 percent, stirring uniformly, standing, filtering, recovering ethanol from the filtrate under reduced pressure, and concentrating to obtain concentrated liquid medicine; preparing sucrose into simple syrup, adding the concentrated liquid medicine, adding water, stirring uniformly, filtering, and filling to obtain the compound herba houttuyniae syrup. The compound herba houttuyniae syrup can be used for treating encephalomyelitis and herpes simplex virus encephalitis. The invention further provides a method for measuring content of the compound herba houttuyniae syrup through high performance liquid chromatography and a gas chromatographic method.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicines, in particular to compound Houttuynia cordata syrup and its pharmaceutical use and detection method for treating encephalomyelitis. Background technique [0002] Herpes simplex virus encephalitis (HSVE), abbreviated as herpes simplex encephalitis (HSE), is the most common non-epidemic viral encephalitis clinically, with both mortality and disability rates quite high. More than 90% of herpes simplex virus encephalitis caused by herpes simplex virus type 1 (herpes simplex virus type 1, HSV-1). [0003] HSVE often involves the temporal lobe, frontal lobe, and limbic system of the brain, causing hemorrhage and necrosis of brain tissue, so it is also called acute necrotizing encephalitis or hemorrhagic encephalitis. Since HSVE has the characteristics of high mortality, serious condition, and rapid development, and the therapeutic effect is affected by the patient's level of consciousness ...
