Simultaneous Determination of Albiflorin, Cinnamaldehyde, Cinnamic Acid, Daidzin, Glycyrrhizin, Liquiritin, Paeoniflorin and Puerarin in Galgeun-tang by HPLC-PDA
Objectives: We investigated to develop and validate HPLC-PDA methods for simultaneous determination of eight constituents in Galgeun-tang (GGT). Methods: Reverse-phase chromatography using a Gemini C18 column operating at 40°C, and photodiode array (PDA) detection at 230 nm, 254 nm, and 280 nm, were...

Zusammenfassung: | Objectives: We investigated to develop and validate HPLC-PDA methods for simultaneous determination of eight constituents in Galgeun-tang (GGT).
Methods: Reverse-phase chromatography using a Gemini C18 column operating at 40°C, and photodiode array (PDA) detection at 230 nm, 254 nm, and 280 nm, were used for quantification of the eight marker components of GGT. The mobile phase using a gradient flow consisted of two solvent systems. Solvent A was 1.0% (v/v) aqueous acetic acid and solvent B was acetonitrile with 1.0% (v/v) acetic acid.
Results: Calibration curves were acquired with r2 > 0.9999, and the relative standard deviation (RSD) values (%) for intra- and inter-day precision were less than 3.0%. The recovery rate of each component was in the range of 87.33-101.38%, with an RSD less than 7.0%. The contents of the eight components in GGT were 1.98-12.17 mg/g.
Conclusions: The established method will be applied for the quantification of marker components in GGT. KCI Citation Count: 6 |
