Abstract

This study aimed to evaluate the effect of ethanolic extract of leaves and fruits of Banisteriopsis oxyclada on seedling growth of wild poinsettia and barnyardgrass. Crude ethanolic extract was prepared at a proportion of 100 g of dry plant matter for 500 mL of ethanol. Through this, the extracts were solubilized in buffer solution and dimethyl sulfoxide (DMSO), at the concentrations 10.0; 7.5; 5.0; and 2.5 mg/mL. The growth of roots, shoots, and seedling root metaxylem cells were evaluated. Ethanolic extracts of leaves and fruits of B. oxyclada inhibited root growth of barnyardgrass and wild poinsettia seedlings, with a concentration-dependent effect. Decreased shoot growth was observed only in wild poinsettia seedlings. Decreased root growth in wild poinsettia seedlings may be related to decreased elongation in metaxylem cells. Banisteriopsis oxyclada shows phytotoxic properties and it may be regarded as an alternative to control the weeds under study, having natural products as a basis.
