The aqueous and methanolic extracts of 110 crude drugs were screened for hyaluronidase inhibitory activity using a microplate assay. Among them, MeOH extract of 15 crude drugs inhibited more than 80% of hyauluronidase activity at the concentration of 5mg/ml. The active principles of Anemarrhenae Rhizoma, Rhei Rhizoma, Ephedrae Herba, Pteropi Faeces and Ginseng Radix alba were transferred into organic solvents.
