ABSTRACT
<p><b>OBJECTIVE</b>To establish fingerprints for Poecilobdella manillensis from Guangxi province using the high performance capillary electrophoresis (HPCE) method.</p><p><b>METHOD</b>Electrophoresis was performed on a fused silica capillary column (75 microm x 56 cm), with 25 mmol x L(-1) Na2HPO4-120 mmol x L(-1) Tris-16 mmol x L(-1) SDS (adjusted to pH 12.0 with 1 mol x L(-1) NaOH ) as the running buffer. The applied voltage was 17 kV, the temperature was 25 degrees C and the detection wavelength was 254 nm. The sample's hydrodynamic injection was 3.4 kPa x 6s and the duration was 27 min.</p><p><b>RESULT</b>HPCE fingerprint was established with 13 common peaks. The similarity between fingerprints of P. manillensis in 10 batches and control fingerprints was more than 0.98.</p><p><b>CONCLUSION</b>The method is so precise, reproducible and stable that it could be used as a new means for the quality control of P. manillensis.</p>
