The structures of all isolates were elucidated by conventional methods, spectroscopic analysis, including 1D and 2D NMR, and by HRESI-MS as well.EnglishOctober University for Modern Sciences and Artsجامعة أكتوبر للعلوم الحديثة والآدابUniversity of Modern Sciences and ArtsMSA UniversityCraniofacial Bone EngineeringBone EngineeringTissue Engineering3-O-?-(6?-O-galloylglucoside)-7-O-?-glucosideAmmania auricultata (Lythraceae)Flavonolsflavonol derivativeglucosideacylationcarbon nuclear magnetic resonancechemical structurechemistryelectrospray mass spectrometryisolation and purificationLythraceaemedicinal plantphytotherapyultraviolet spectrophotometryAcylationCarbon-13 Magnetic Resonance SpectroscopyFlavonolsGlucosidesLythraceaeMolecular StructurePhytotherapyPlants, MedicinalSpectrometry, Mass, Electrospray IonizationSpectrophotometry, UltravioletArticlehttps://doi.org/10.1515/znc-2014-4165PubMed ID 25854842
