Characterization of adulteration of “espinheira santa” (Maytenus ilicifolia andMaytenus aquifolium, Celastraceae) hydroalcoholic extracts withSorocea bomplandii (Moraceae) by high-performance thin layer chromatography

Abstract

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.

1H HR-MAS NMR-Based Metabolomic Fingerprinting to Distinguish Morphological Similarities and Metabolic Profiles of Maytenus ilicifolia, a Brazilian Medicinal Plant

“…Over the last few decades, the quality control of M. ilicifolia has been concentrated on targeted biomarkers (flavanols), as determined by chromatographic, spectrometric, and spectroscopic methods. − However, some of these procedures are laborious in their design. As an alternative to these procedures, − nuclear magnetic resonance (NMR) spectroscopy can also simultaneously detect molecules with an exact structural configuration in a quantitative and reproducible manner . NMR spectroscopy has excellent utility in metabolomics fingerprint and profile investigations to address the quality control of botanicals , and of foods and beverages .…”
