ABSTRACT
AIM: To establish the qualitative method for determining hirudo in Zhiyu Granule (Scorpio, Scolopendra, Rhizoma Coptidis, Radix Astragali, etc.) METHODS: Hirudo was determined by anti-thrombin bioactivity method after being extracted from Zhiyu Granule using 95% ethanol. RESULTS: The difference between Zhiyu Granule and the control sample without hirude was significant and easy to identify. CONCLUSION: After being extracted by 95% ethanol, hirudo can be identified from other anti-thrombin bioactivity components in prescription.
