Background: The main antibacterial component of Pulsatilla chinensis is anemonin, which has strong antibacterial effect, so it is studied. The Pulsatilla chinensis is one of the diseases that are difficult to solve in the growth of ginseng, but chemical control not only causes harm to the environment, but also has residues on ginseng itself. Pulsatilla is a good medicinal plant. It will have a certain effect on the prevention and treatment of ginseng disease, and it can do no residue, no harm to ginseng. Objective: This experiment can provide effective data support for the prevention and treatment of Pulsatilla chinensis. Method: In this experiment, Pulsatilla Chinensis was used as experimental materials to extract plant by reflux, ultrasonic extraction methods, the content of anemonin in each single factor experiment was determined by HPLC. According to the content, the response surface analysis method was used to find the best extraction process, and the mycelium growth rate method was further used to determine the antifungal effect of Alternaria panax. Results: The EC50 value of P. Chinensis extract to A. panax was methanol extract < acetone extract < ethanol extract in order from small to large; The optimum extraction conditions of anemonin, the effective component of P. Chinensis methanol extract, were as follows: methanol volume fraction 87%, extraction time 2 h, solid-liquid ratio 20 (V: m), the optimum extraction amount was 3.760 μg·g-1.
