Effect of pectin substances on contractile activity of the uterine myometrium in rats.
We studied the effects of peptides from Amaranthus cruentus L., Rauwolfia serpentina Benth., and citrus plants on contractile activity of the uterine myometrium in rats. Pectin substances inhibited spontaneous contractile activity of uterine muscles and abolished the stimulatory effect of oxytocin. Pectins had a synergistic effect with epinephrine and acetylcholine.
