Identification and Quantification of Kaempferol From Ethyl Acetate Fraction of Pluchea wallichiana DC Leaves

Abstract

P. wallichiana DC, commonly known as camphor weed, is practically used in treatment of inflammatory disorders. Identification of kaempferol was done using High-Resolution Liquid Chromatography-Mass Spectrometry (HRLC-MS). High-Performance Thin-Layer Chromatography (HPTLC) method was performed and validated for the quantification of kaempferol. With a correlation coefficient of 0.997, the linearity range for kaempferol was 200 to 700 ng/spot. The suggested method had a recovery rate between 99.60 and 99.85 %. Limit of detection and Limit of quantification were determined to be 25 and 76.47 ng per spot, respectively. The amount of kaempferol was found to be 7.2% in ethyl acetate fraction of leaves. This is the first report of identification and quantification of kaempferol from P. wallichiana DC through HRLC-MS and HPTLC methods.
