Chemical constituents isolated from <em>Mandevilla dardonoi</em> (Apocynaceae)

Abstract

The aim of this study was to obtain bioactive compounds from Mandevilla dardonoi (Apocynaceae), in order to contribute positively to the discovery of new sources of active natural substances. Based on this, the compounds obtained from the ethyl acetate phase were isolated by medium pressure column chromatography and high performance liquid chromatography and identified by nuclear magnetic resonance (1 H) and electrospray mass spectrometry. It was possible to isolate 6 chlorogenic acids: 3-caffeoylquinic (3-ACQ), 4-caffeoylquinic (4-ACQ), 5-caffeoylquinic (5-ACQ), 3,4-dicaffeoylquinic 4-diACQ), 3,5dicaffeoylquinic (3,5-diACQ) and 4,5dicaffeoylquinic (4,5-diACQ) acids. The research contributed positively to the expansion of the knowledge about the genus Mandevilla and especially of the species M. dardonoi, which did not exist reports of phytochemical studies in the literature.
