The Chemical Investigations of the Mangrove Plant Avicennia marina and its Endophytes

A diverse array of bioactive compounds have been isolated and characterized from the mangrove plant Avicen- nia marina and its endophytes. Extensive chemical investigations of the different parts (barks, leaves, twigs, etc.) of the mangrove plant A. marina and its endophytes (mainly endophytic fungi) resulted in the reporting of the isolation of 123 compounds, and most of them are new or novel compounds. Most of compounds produced by the endophytes were differ- ent from the chemical components of the host A. marina, but it can still be found that some metabolites of the endophytes and some chemical components of the host possess the same structure unit. It suggested that there exist some biogenetic relationships between the endophytes and its host. Their biological activities, structural and stereochemical assignments are reported.
