Descrizione generale

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

Applicazioni

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

Oenothein B, a macrocircular dimeric ellagitannin, was found to be a potent and specific inhibitor of poly(ADP-ribose) glycohydrolase. Oenothein B suppressed glucocorticoid-sensitive mouse mammary tumor virus (MMTV) transcription in 34I cells. This suppression was accompanied by inhibition of glucocorticoid-induced endogeneous
