A kind of traditional Chinese medicine extract with antiviral effect and preparation method and application thereof |
| abstract |
The invention relates to the technical field of traditional Chinese medicine, and specifically discloses a traditional Chinese medicine extract with antiviral effect and a preparation method and application thereof. The preparation method of the traditional Chinese medicine extract with antiviral effect specifically comprises the following steps: (1) extracting the soap bark with ethanol to obtain the soap bark alcohol extract; (2) adding water to the prepared bark bark alcohol extract to suspend , and then directly extracted with ethyl acetate to obtain ethyl acetate extract of soap thorn; further, the ethyl acetate extract of thorn thorn was placed on a macroporous resin column, and firstly eluted with an aqueous ethanol solution with a volume fraction of 25-30%. Then use 40-45% ethanol aqueous solution to elute; collect the 40-45% ethanol aqueous solution elution part, concentrate and dry to obtain the Chinese medicine extract with antiviral effect. The traditional Chinese medicine extract prepared by the method has good antiviral effect on influenza virus, hepatitis B virus or respiratory syncytial virus, especially on respiratory syncytial virus, the antiviral effect is more significant. |
