| Abstract: | Objectiv： To research the extraction process of the compound of Gentiana, optimization of the optimum conditions, to lay the foundation to research and treatment of the diarrhea of piglets, calves and other young animals. Methods： Use Orthogonal experimental method, detect Gentiopicroside for targets, research the impact of solid-liquid ratio, extraction times, ultrasound time and ethanol concentration four factors to Gentiopicroside content. Results： Optimum extraction conditions： ethanol of 70%, solid-liquid ratio of 20 times, extraction times of 2 times, each ultrasound time needs 5 hours. |
