Objective:To determinate the contents of protocatechuic acid
chlorogenic acid
caffeic acid and rutinin in Blumea riparia by HPLC
and provide references for its quality control. Method:The HPLC analysis was carried out by Inertsil ODS-3 column (4.6 mm×250 mm
5 μm) with acetonitrile (A)-0.1% phosphoric acid solution (B) as the mobile phase for gradient elution. The detection wavelength was set at 256 nm (0-15 min
protocatechuic acid)
327 nm (15-30 min
chlorogenic acid and caffeic acid)
and 360 nm (30-60 min
rutin). In addition
the flow rate was 1.0 mL·min-1 and column temperature was 20℃. Result:Protocatechuic acid
chlorogenic acid
caffeic acid and rutin showed good linearity in the range of 0.007-0.13 μg (r=0.999 98)
0.219-4.38 μg (r=0.999 94)
0.014-0.28 μg (r=0.999 97) and 0.049-0.98 μg (r=0.999 97) respectively
and the recovery of those 4 components were 98.84% (RSD 2.2%)
101.16% (RSD 0.9%)
98.00% (RSD 2.8%) and 101.73% (RSD 1.4%) respectively. The content determination results showed that the contents of protocatechuic acid
chlorogenic acid and rutinin were higher in Pingguo samples; and the content of caffeic acid was higher in Jingxi and Sichuan samples. Conclusion:The established method can be used to determine the contents of protocatechuic acid
chlorogenic acid
caffeic acid and rutin. Such stable
reliable and repeatable analytical model can provide a reference for the quality evaluation and its control on Blumea riparia.
