To provide a skin care preparation which is derived from a natural product, is excellent in biological safety, and exhibits functions of preventing or improving skin roughness, improving the transparency of the skin, and suppressing cell aging by suppressing the secretion of inflammatory substances (cytokine and chemokine) in the skin.SOLUTION: An extract of Gentiana lutea belonging to the genus Gentiana of the family Gentianaceae and an extract of Bletilla striata belonging to the genus Bletilla of the family Orchidaceae are used as active ingredients for suppressing the secretion of inflammatory factor (cytokine and chemokine).SELECTED DRAWING: None

The present application relates to the technical field of medicinal plant tissue culture, in particular to a rapid virus-free cloning method and reagent combination for medicinal plant tissue culture. The method comprises the following steps: pretreatment and disinfection of explants, precise virus elimination, preparation of dynamic adaptive medium, rapid propagation, real-time high-throughput detection of virus-free, seedling raising and transplanting, etc. The reagent combination comprises a multifunctional degradable reagent kit, intelligent response type nano disinfection microcapsules, special reagents such as composite virus elimination liquid, etc. The virus elimination rate is greater than or equal to 95%, the survival rate of explants is greater than or equal to 90%, the propagation cycle is shortened by 30%, the detection time is less than or equal to 2 hours, the survival rate of transplanting is greater than or equal to 85%, and the degradation rate of reagents is greater than or equal to 90%. The present application is suitable for herbaceous, woody and liana medicinal plants of the families of Araliaceae, Eucommiaceae, Orchidaceae and Campanulaceae, etc., can realize stable virus elimination and propagation effect, significantly improve the virus-free cloning efficiency and seedling quality, and meet the green production demand.

The application discloses application of gastrodin in preparation of SCA3 disease treatment drugs, and the gastrodin is a compound extracted from Gastrodia elata Blume of the Orchidaceae family and has therapeutic effects on neurasthenia, headache and the like. Researches show that the gastrodin can significantly reduce inclusion bodies caused by mutant ataxin-3, improve soluble ataxin-3 protein levels, has no toxic side effects on HEK293T cells, and regulates the specific molecular mechanism of inclusion bodies formed by ataxin-3 through an AKT / ERK signal axis. The application aims to reveal the application of the gastrodin in playing a neuroprotective effect on SCA3 diseases, enrich new uses of old drugs, and provide a new idea for prevention and treatment of other neurodegenerative diseases.
