To develop a high performance capillary electrophoresis method for Citrus aurantium fingerprints to control its quality.
The background electrolyte (BGE) was an 80 mmol x L(-1) boric acid solution containing 15 mmol x L(-1) borate. The pH of the BGE was adjusted to 9.70 with KOH solution. The detection wavelength was 201 nm and a voltage of 16 kV was applied. The sample hydrodynamic injection was 0.4 ps with a duration time of 8 sec. C. aurantium was extracted by water and a set of capillary electrophoresis fingerprints (CEFP) containing 12 co-possessing peaks was obtained.
There were good similarities between the standard CEFP and each set of CEFP of C. aurantium collected from eleven different places, and their similarity coefficients were between 0.973 and 0.996.
The CEFP has acceptable precision, reproducibility and stability and can be used for the quality control of C. aurantium.
建立一种用于枳壳指纹图谱分析以控制其质量的高效毛细管电泳方法。
背景电解质(BGE)为含15 mmol·L⁻¹硼酸盐的80 mmol·L⁻¹硼酸溶液,用氢氧化钾溶液将BGE的pH值调至9.70。检测波长为201 nm,施加电压16 kV。样品采用流体动力学进样,进样量0.4 psi,持续时间8秒。枳壳用水提取,获得了一组包含12个共有峰的毛细管电泳指纹图谱(CEFP)。
标准CEFP与从11个不同地点采集的枳壳的每组CEFP之间具有良好的相似度,其相似系数在0.973至0.996之间。
该CEFP具有可接受的精密度、重现性和稳定性,可用于枳壳的质量控制。
