    Journal: Zhongguo Zhong Yao Za Zhi; 2012 Feb; 37(4):495-9. PubMed ID: 22667151.
    Abstract:
    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 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. 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.
