Study on HPCE fingerprints of Poecilobdella manillensis from Guangxi province

Objective:To establish fingerprints for Poecilobdella manillensis from Guangxi province using the high performance capillary electrophoresis(HPCE) method.Method:Electrophoresis was performed on a fused silica capillary column(75 μm×56 cm),with 25 mmol·L-1 Na2HPO4-120 mmol·L-1 Tris-16 mmol·L-1 SDS(adjusted to pH 12.0 with 1 mol·L-1 NaOH) as the running buffer.The applied voltage was 17 kV,the temperature was 25 ℃ and the detection wavelength was 254 nm.The sample’s hydrodynamic injection was 3.4 kPa×6 s and the duration was 27 min.Result: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.Conclusion:The method is so precise,reproducible and stable that it could be used as a new means for the quality control of P.manillensis.
