Determination of galangin in commercial extracts of Alpinia officinarum by RP-HPLC-DAD
Alpinia officinarum has been used by long time in the traditional medicine and several commercial extracts containing it are available on the market. In this paper a reversed phase high performance liquid chromatography-diode array detection (RP-HPLC-DAD) method for Alpinia officinarum preparations...

| description |
Alpinia officinarum has been used by long time in the traditional medicine and several commercial extracts containing it are available on the market. In this paper a reversed phase high performance liquid chromatography-diode array detection (RP-HPLC-DAD) method for Alpinia officinarum preparations was proposed using galangin as a marker. The quantification was undertaken by a combination of RP-HPLC-DAD. The LC system employed a Gemini Phenomenex RP-18 column with phosphoric acid, tetrahydrofuran and acetonitrile as mobile phase and detection at 267 nm. The method validation was throughout satisfactory. The determination coefficient was r<sup>2</sup> = 0.998 with LOD 0.48 µg mL<sup>-1</sup> and LOQ 1.59 µg mL<sup>-1</sup> The results of precision (RSD < 2.82) and accuracy (99.9 %, 100.4 %, 102.2 %) with . RSD less than 2.7 %, were satisfactory. The analytical method was applied to commercial extracts, and was suitable to provide qualitative and quantitative information for the quality control to commercial preparations. |
