Title: Two new chalcones from <i>Clerodendrum phlomidis</i>
Abstract: AbstractTwo new chalcones, 3,2′,3′-trihydroxy-4′-methoxychalcone (1) and 3,2′-dihydroxy-4′,6′-dimethoxychalcone (2), were isolated from the seeds of Clerodendrum phlomidis together with three known flavonoids, 5-hydroxy-7-methoxyflavanone (3), 5-hydroxy-7-methoxyflavone (4), and kaempferol-3-O-α-l-rhamnopyranoside (5). The structures of the new compounds 1 and 2 have been established mainly on the basis of 1D and 2D NMR studies.Keywords:: Clerodendrum phlomidisVerbenaceaeseedschalcones AcknowledgementsThe authors thank Dr Arul Marie and Mr Dubost Lionel, Laboratoire de Chimie et Biochimie des Substances Naturelles, MNHN, Paris, France, for providing mass spectral data.
