英文摘要	A fast capillary zone electrophoresis (cze) method for the simultaneous determination of four cyclic diarylheptanoids (rhoiptelol, rh; juglanin a, ja; juglanin b, jb; juglanin c, jc) and an a-tetralone derivative (sclerone, sc) in the extract of the green walnut husks (juglans regia l.) was developed. the optimized buffer was composed of 25 mm sodium tetraborate at ph 10.3. the applied voltage was 20 kv and the capillary temperature was kept constant at 20 c. the detection wavelength was set at 220nm using a photodiode array detection. the effects of several ce parameters, including ph value, buffer concentration, applied voltage and separation temperature on the separation were investigated systematically. regression equations showed good linear relationships (correlation coefficients: 0.9996-0.9999) between the peak area of each compound (rh, ja, jb, jc and sc) and its concentration accordingly. the relative standard deviations (r.s.d.) of the migration time and peak area were less than 0.57 and 3.44% (intra-day), and 0.97 and 3.71% (inter-day), respectively. the contents of the five active compounds in the green walnut husks (j. regia l.) from different origins were determined with satisfactory repeatability and recovery.
