Abstract:
OBJECTIVE:To establish a method for the simultan eous determination of the contents of 12 flavonoids in Quzhiqiao. METHODS :HPLC method was adopted. The determination was performed on Agilent Extend C 18 column with mobile phase consisted of 0.1% formic acid-acetonitrile (gradient elution )at the flow rate of 1.0 mL/min. The column temperature was set at 35 ℃. The detection wavelength was set at 330 nm,and sample size was 10 μL. The contents of 12 components(such as eriocitrin,narirutin,naringin,naringenin,hesperidin,neohesperidin,hesperide hydrate ,luteolin,hesperide,nobiletin,hesperetin and hesperidolactone )in 10 batches of Quzhiqiao from different collection places were determined. RESULTS :The linear range of eriocitrin,narirutin,naringin,naringenin,hesperidin,neohesperidin,hesperide hydrate ,luteolin,hesperide,nobiletin,hesperetin and hesperidolactone were 1.65-16.51,4.50-45.02,35.41-354.12,4.11-41.12,2.29-22.86,34.96-349.56,1.42-14.15,1.50-15.04, 1.83-18.28,1.51-15.08,1.61-16.12,1.28-12.84 μg/mL,respectively(all r>0.999 7). The detection limits were 0.165 1,0.450 2, 3.541 2,0.411 2,0.228 6,3.495 6,0.141 5,0.150 4,0.182 8,0.150 8,0.161 2,0.128 4 μg/mL,respectively. The limits of quantitation were 0.547 8,1.487 4,11.663 3,1.360 3,0.758 3,11.594 9,0.466 3,0.497 1,0.601 2,0.499 9,0.532 3,0.424 6 μg/mL,respectively. RSDs of precision (n=6),reproducibility(n=6)and stability (24 h,n=7)tests were all lower than 3%. The average recoveries were 99.50%,99.61%,98.18%,98.85%,98.48%,98.50%,98.25%,99.91%,103.13%,98.82%, 98.44% , 100.29% (RSD=1.49% -2.38% , n=6). The contents of the above 12 components in 10 batches of samples from different collection places were 1.995 5-2.648 8,4.317 7- 5.005 1,33.215 5-34.054 6,3.140 4-3.471 5,3.221 2-3.748 8, 42.746 6-44.026 6,0.202 7-0.239 4,0.191 2-0.208 8,0.080 3- 0.097 9,0.291 9-0.307 1,0.119 9-0.149 1,0.082 7-0.089 8 mg/g. CONC LUSIONS:The method is accurate ,reliable,simple and efficient,which can be used to simultaneous determination of the contents of 12 flavonoids in Quzhiqiao ,and to provide reference for the establishment of quality control standards of Quzhiqiao.
