摘要

The aqueous extract of Solanum torvum (EASt), at concentrations ranging from 10-1 to 6.10-1mg/ml, caused a dose-dependent decrease in the amplitude of spontaneous rhythmic contractions and basal toneof isolated rabbit’s duodenum. This myorelaxation was dose dependently antagonized by propranolol (10-4 to10-2 mg/ml). In a physiological solution devoid of calcium, EASt completely inhibits intestinal rhythmiccontractions and causes a decrease in basal tone. A completeinhibition of intestinal rhythmic contractions wasalso observed by adding EASt to a 0 Ca2+physiological solution+ EDTA. However, in a 0 Ca2+ solution+ EGTA,the crude extract of Solanum torvum did not exhibit any effect.EASt therefore has myorelaxant properties and might act by promoting the decrease of intracellular calciumconcentration in the intestinal smooth muscleby stimulating adrenergic receptors and blocking the intracellularand extracellular calcium channels.Detection of phytocompounds such as tannins and flavonoidsin the aqueous extract of Solanum torvum throughphytochemical screening which antispasmodic, anti-diarrheal and myorelaxant effects have been demonstratedby other authors could justify its myorelaxant properties and traditional use as an anti-diarrheal.
