| Abstract: | OBJECTIVE:To select an optimal extraction technique of Whitmania pigra whiman.METHODS:The afˉfecting factors such as variety of solvent,temperature,time,the amount of solvent and the frequency of the extraction were studied on the basis of protein content in the hirudo extract and activated partial thromboplastin time(APTT).RESULTS:The optimum extraction result was obtained in4%NaCl solvent of10-fold as much as the medicine with3times of extraction at60℃for6h((3h+2h+1h).CONCLUSION:The present technique is simple,scientific and practicable. |
