ABSTRACT
AIM:
Bioactive constituents were expected to be obtained from the roots of Angelica morri Hayata.METHOD:
They were extracted with 95% alcohol and isolated by using column chromatography and recrystallization methods. The structures were elucidated by means of physico-chemical data and UV,IR,1HNMR, 13CNMR,and EIMS. The inhibitory effect on the constriction of rat aortic rings was induced by K+ or Ca2+.RESULT:
3′S-(-)-hamaudol,3′S-(-)-Ο-acetylhamaudol,3′R-(+)-hamaudol,and (±)-hamaudol were isolated from the pieces of Radix Angelica Morri. The inhibitory rate of 3′S-(-)-Ο-acetylhamaudol and (±)-hamaudol on the above pharmacologic model appears the relation of quantity response.CONCLUSION:
All the above compounds were found in this species for the first time,and(±)-hamaudol is a new. One of effect mechanisms of 3′S-(-)-Ο-acetylhamaudol and (±)-hamaudol diluted aorta could contribute to be inhibiting Ca2+ influx of vascular smooth muscle.
