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]

A method was developed for separation and quantitative determination of oenothein B (OeB) and quercetin glucuronide (QG) in aqueous extract of Epilobii angustifolii herba by HPTLC-densitometry. The analyses were performed on HPTLC RP-18 WF(254) plates with 25% MeCN in water

Species of the genus Epilobium (Onagraceae) have been investigated for their activity against 5 alpha-reductase and aromatase, two enzymes which are involved in the aetiology of benign prostatic hyperplasia (BPH). Activity-guided fractionation has led to the identification of two macrocyclic
