Antibacterial saponins from the leaves of Polyscias fulva (Araliaceae)

Saponins are a major family of secondary metabolites that occur in a wide range of plant species. Bioassay - guided fractionation of extract of the leaves of Polyscias fulva led to the isolation of three known saponins named, 3-O-α-L-arabinopyranosyl-hederagenin (1), 3-O-[α-L-rhamnopyranosyl(1-2)-α-L-arabinopyranosyl]-hederagenin (2) and...

Uterotonic effect of aqueous extract of Launaea taraxacifolia Willd on rat isolated uterine horns

Launaea taraxacifolia is used by the traditional health practitioners in Sokoto to ease labour pains and augment labour thereby facilitating child birth. This study examined the effect of the aqueous extract of the whole plant on isolated uterus from non-pregnant rats pre-treated with stilbestrol and from pregnant rats in late gestation. This was compared to the effects of uterine contraction agonists, namely; oxytocin,...
