| Research Abstract |
By the electroencephalographic measurement after intraperitoneally administration and oral administration of oxypinnatanine in mice, the increase in amount of sleep was observed only in the oral administration.
And it was clear that the concentration in the blood showed lower level after an oral administration of oxypinnatanine from the measurement of the concentration of oxypinnatanine in the blood.
It was clear that oxypinnatanine was metabolized in the body of the mouse and its metabolite showed the effect.
We demonstrated that from consideration of the metabolism in the liver and the stability in the artificial intestinal fluid or artificial gastric fluid of oxypinnatanine, oxypinnatanine are not metabolized in the liver, stomach, and intestine.
Possibility that oxypinnatanine show the sleep improvement effect by the heat release associated with peripheral vasodilation, was suggested from the results of temperature measurement using thermography.
