Descripción

General description

Oenothein B is a dimeric ellagitannin compound which is found commonly in genusOenothera.[1]

Application

Oenothein B may be used as a reference standard for the determination of oenothein B in aqueous extracts of Epilobii angustifolli herba[2] and Epilobium angustifolium L.[3] by high performance thin-layer chromatography (HPTLC)-densitometry, in plant materials by HPLC combined with diode array detector (DAD) and mass spectrometry (MS)[1] and in Eucalyptus globulus leaves by HPLC-DAD coupled to electrospray ionization (EIS) MS.[4]
