title: Phytochemical characteristic and uterotonic effect of aqueous extract of Ficus deltoidea leaves in rats uterus.
abstract: Ficus deltoidea is traditionally consumed by Malay woman to augment labour and hastening parturition. This study was to investigate the phytochemical present and uterotonic activity of F. deltoidea var. Deltoidea (FDD) and F. deltoidea var. Angustifolia (FDA) leaves aqueous extract. FDD and FDA were qualitatively analysed. In uterine contraction activity, adult female Sprague Dawley rats were pretreated with 0.2 mg kg(-1) diethylstilbestrol 24 h to induce oestrus phase. The rats then killed and uterine horns were taken out, cut into two centimetres length and put into organ bath that connected to Powerlab instrument. The uterus separately tested with cumulative concentrations of FDD (10-1280 μg mL(-1)), FDA (10-1280 μg mL(-1)), oxytocin (0.02-0.64 μg mL(-1)) and combination of oxytocin (0.08 μg mL(-1)) with FDD and FDA (10-1280 μg mL(-1)). FDD showed presence of flavonoid, saponin and tannin meanwhile FDA consist of flavonoid, tannin and terpenoid. Result showed FDD, FDA and oxytocin induced a dose-related increase in force of contraction of isolated rat uterus. The maximum uterine contraction (Emax) produced by FDD, FDA and oxytocin were at the concentration 640 μg mL(-1) (EC50, 5.903 ± 0.529 μg mL), 20 μg mL(-1) (EC50, 290.5 ± 0.158 μg mL(-1)) and 0.4 μg mL(-1) (EC50, 0.060 ± 0.011 μg mL(-1)) respectively. Combination effects of oxytocin with FDD and FDA produced Emax at the concentration 80 μg mL(-1) (EC50, 270.3 ± 0.643 μg mL(-1)) and 1280 μg mL(-1) (EC50, 26.83 ± 0.727 μg mL(-1)), respectively. Study indicated F. deltoidea possess contractile effect on uterine contraction. This plant has great potential to develop as natural uterotonic agent in inducing labour and treatment for post-partum haemorrhage.
