A high‐performance thin layer chromatographic (HPTLC) procedure for the characterization of adulteration of “espinheira santa” ( Maytenus ilicifolia and Maytenus aquifolium, Celastraceae) with Sorocea bomplandii (Moraceae), by monitoring their flavonoid content with the aid of diphenylboric acid‐2‐aminoethylester‐polyethylene glycol 400 reagent, is presented. HPTLC data showed the predominance of highly glycosylated quercetin and kaempferol derivatives. The derivatized flavonoids were shown to be the best markers for distinguishing between authentic and adulterated drug samples, with several advantages over triterpene analysis.
