Ellagitannins, ellagic acid derivatives, stilbenes and flavonoids in antibacterial stem bark and leaf extracts of African medicinal plants Combretum psidioides and Combretum fragrans

Combretum psidioides and C. fragrans are used as decoctions for diarrhea and wounds in African traditional medicine [1]. In Nigeria, C. fragrans is used for the treatment of Blackleg disease in cattle among Fulani pastoralists. There exists no research on antibacterial compounds of these species but some phytochemical investigations have been performed on C. psidioides; fourteen phenanthrenes and stilbenes are known from the heart wood and pentacyclic triterpenoids have been characterized from the roots [2].
