The aim of this study was to investigate the chemical composition and anticancer effect of the leaf essential oil of Xylopia frutescens in experimental models. The chemical composition of the essential oil was analysed by GC/FID and GC/MS. In vitro cytotoxic activity of the essential oil was determined on cultured tumour cells. In vivo antitumour activity was assessed in Sarcoma 180-bearing mic...

Ent-7α-hydroxytrachyloban-18-oic acid, a trachylobane diterpene from Xylopia langsdorfiana, has previously been shown to relax the guinea-pig trachea in a concentration-dependent manner. In this study we aimed to elucidate the mechanisms underlying this action and so contribute to the discovery of natural products with therapeutic potential. A possible interaction between diterpene and the Ca(2...

in this paper the taxonomy of some previously reported taxa as cercospora apii s.lat. in iran, is discussed and some new records are listed. cercospora species on abelia grandiflora (c. deutziae), erythrina crista-galli (c. erythrinicola), euphorbia heterophylla (c. pulcherrimae) and zanthedeschia aethiopica (c. richardiicola) are new for mycobiota of iran. cercospora iridis which was previousl...
