- W2370721505 abstract "Veratrine is extracted through the methods of supercritical CO2 extraction process and improved alkaline ethanol immersion.[Methods] The methods of supercritical CO2 extraction process and improved alkaline ethanol immersion for veratrine were compared according to the parameters of the content of veratrum alkaloid and extraction time.[Results] Under the optimum conditions,through the method of supercritical CO2 extraction process,the extraction rate of veratrum crude was 3.13%,the mass fraction of veratrum alkaloid(veratrum alkaloid/crude) was 14.38% and the extraction time is 3 h;through the method of improved alkaline ethanol immersion,the extraction rate of veratrum crude was 10.15%,the mass fraction of veratrum alkaloid was 4.35% and the extraction time was 72 h.[Conclusions] Compared with traditional extraction methods,the extraction rate of supercritical CO2 extraction process for veratrine is higher and the time is shorter.The proportion of alkaloids in crude is higher,the impurities of crude and the turbidity are lower.The whole process is environmental and efficient." @default.
