Abstract

Adulteration of herbal supplements is a major issue for many countries. A simple and reliable HPLC-PDA method was developed for quantification of aldose reductase inhibitory flavonoids rutin, quercetin, and kaempferol. The chromatographic separation was performed on a Fortis C18 column in gradient mode with detection at 267 nm. The presence of these markers was confirmed through the accurate m/z values and MS/MS data obtained using quadruple time of flight mass spectrometry (QTOF-MS). The proposed method was successfully applied to examine the amount of these active constituents in antiobese polyherbal formulation and plant extract of Gymnema sylvestre.
