Its bark contains triterpenoid saponin, which is called Albizzia oxytocin.

[pharmacological action] unknown. In the same genus, there is oxytocin from Albizia julibrissin. A. gurnmmifera, a plant of the same genus containing this component, is used for induced labor or abortion in East Africa. In vitro experiments, oxytocin can cause contractions of guinea pig or human uterus when it is quiet, but it can increase contractile force or frequency when the uterus has spontaneous activity. In the isolated small intestine of guinea pig, the contraction was not induced even at high concentration. In anesthetized animals (guinea pigs, rabbits, cats and monkeys), oxytocin (0.1-8 mg / kg) by intravenous injection can cause a short-term decrease in blood pressure, increase the activity of eutopic uterus, especially the pregnant uterus. Atropine and antihistamines can not block this effect (except monkeys). For all kinds of non anesthetized animals, oxytocin can cause abortion within 12 hours during each period of pregnancy, a large number of animals are toxic, the lethal dose usually does not immediately cause death, but in 12 hours, sometimes to 7 days later; the cause of death has not yet been determined, and necrosis of renal tubules (rabbits) has been observed, especially in the liver of mice and rats There was no significant and constant change in ECG even before death, and the toxicity of oral administration was much less than that of injection.
