Alkaloids in Erythrina by UPLC-ESI-MS and In Vivo Hypotensive Potential of Extractive Preparations

<div>Illustrative chromatograms obtained from analysis of Erythrina leaves extracts, with detection at 280 nm. (a) E. falcata: 1: crude hydroethanolic extract at 40%; 2: ethanolic residual fraction. (b) E. crista-galli: 1: crude hydroethanolic extract at 40%; 2: ethanolic residual fraction. (c) UV profile of major chromatographic peak from E. falcata. (d) UV profile of major chromatographic peak from E. crista-galli.</div>
