ABSTRACT
OBJECTIVE:
To establish a high performance capillary electrophoresis (HPCE) method for simultaneous determination of aucubin, geniposide, pinoresinol diglucoside, harpagide, and chlorogenic acid in Eucommiae Cortex.METHODS:
60 mmol·L-1 sodium borate-20 mmol·L-1 sodium dihydrogen phosphate-10% methanol was used as buffer solution (pH 10.0), un-coated fused silica capillary (64.5 cm×75 μm id, 56 cm of effective length) was used, separation voltage was 20 kV, detection wavelength was 210 nm, column temperature was maintained at 25°C, and sample was injected at 5 kPa×6 s.RESULTS:
Five index components showed good linearity (r>0.9973) in the range of the tested concentration. The average recoveries of the method were between 96.63%-103.73%.CONCLUSION:
The method is simple, accurate and reproducible, and can be used for quality control of Eucommiae Cortex. Copyright 2012 by the Chinese Pharmaceutical Association.
