Study on HPLC Fingerprint of Flavonoids in Ultramicro-powders of Houttuynia Cordata Thunb |
|
|
Abstract: The fingerprinting of flavonoids in ultramicro-powders of Houttuynia cordata Thunb. is carried out by HPLC.The chromatographic conditions are as follows: SHIM-PACK VP-C18 column(250 mm×4.6 mm,10 ?滋m) is used,and CH3CN-1%HCOOH gradient is chosen as liquid phase,with flow speed of 1.0 ml/min and the detection wavelength of 254 nm. The fingerprint of ultramicro-powders of Houttuynia cordata is established, with 7 common peaks in the fingerprint. The method and data can be used to control the quality of the ultramicro-powders of Houttuynia cordata.
