Objective To establish the best extraction method for Hypericum scabrum L .Methods Use Hyperoside as the reference substances ,HPLC method to determinate the concentration of Hyperoside . During the extracting process ,five main factors ,including extracting solvent and method ,concentration of extracting solution ,solid‐liquid ratio ,refluxing time and extracting times ,were studied by using single factor analysis method .And based on the single‐factor analysis ,the L9 (34 )orthogonal was designed and optimized the best conditions extracting the hyperoside from the Hypericum scabrum L .Results The op‐timal extracting condition :ethanol concentration 70% ,solid‐liquid ration 1∶50 ,95 ℃ water‐bath reflux 30min .According to the congdiction mentioned above ,the content of Hyperoside which were extracted from Hypericum scabrum L could reach 3 .35 mg /g .Conclusion The method established for Hypericum scabrum L is simple ,feasible and reproducible ,and it can be used as Hypericum scabrum L extracting method .
