ABSTRACT
<p><b>OBJECTIVE</b>Applying for the activity of enzyme in vitro,the research optimized the best preparation procedure for the anticoagulated blood region from Lumbricus.</p><p><b>METHOD</b>All through our experiment, the content of protein and theactivity of enzyme were examined. The extraction process, the refining technology, concentration processes of Lumbricus were optimized with single factor checking and orthogonal design method.</p><p><b>RESULT</b>At 37 degrees C, the coarse powder of Lumbricus soaking with 15 fold of 0.9% sodium chloride and ultrasonic extracting 40 minites for three times was the best ultrasonic extraction. Utrafiltration membrane with molecular weights of 30 x 10(3) for refining and 10 x 10(3) for concentrating were selected.</p><p><b>CONCLUSION</b>Ultrasonic extraction and membrane separation technology, to well improve the effect of purification for the anticoagulant site of Lumbricus, is conducive to further study.</p>
