A phytochemical investigation of Dictamnus angustifolius led to the isolation of 14 compounds, including six furoquinoline alkaloids (1-6), two sesquiterpenoids (7, 8) and six flavonoids (9-14). The structures of these compounds were identified by spectroscopic methods and a comparison of their data with those reported in the literature. This is the first report of three furoquinoline alkaloids 1-3 and six flavonoids 9-14 from the genus Dictamnus and the first isolation of compounds 4-8 from D. angustifolius. The chemotaxonomic significance of furoquinoline alkaloids and sesquiterpenoids has also been summarized. (C) 2016 Elsevier Ltd. All rights reserved.
