To establish fingerprints for Poecilobdella manillensis from Guangxi province using the high performance capillary electrophoresis (HPCE) 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.
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.
The method is so precise, reproducible and stable that it could be used as a new means for the quality control of P. manillensis.
采用高效毛细管电泳(HPCE)法建立广西马尼拉宽体金线蛭的指纹图谱。
在熔融石英毛细管柱(75μm×56cm)上进行电泳,以25mmol·L⁻¹ Na₂HPO₄ - 120mmol·L⁻¹ Tris - 16mmol·L⁻¹ SDS(用1mol·L⁻¹ NaOH调至pH 12.0)作为运行缓冲液。施加电压为17kV,温度为25℃,检测波长为254nm。样品的流体动力学进样为3.4kPa×6s,持续时间为27min。
建立了具有13个共有峰的HPCE指纹图谱。10批马尼拉宽体金线蛭指纹图谱与对照指纹图谱的相似度均大于0.98。
该方法精密、可重复且稳定,可作为马尼拉宽体金线蛭质量控制的新手段。
