本文对中药麝香中主要芳香成分——麝香酮经氚标记于小鼠作体内动力学研究。实验结果~3H-麝香酮单次静脉药给,其分布半衰期为1.4分,说明该药进入体内很快分布到有关器官和组织,迅速发挥药效。单次灌胃给药其吸收半衰期12.6分,说明吸收迅速,为阐明芳香开窍,并用于急症提供一定的理论依据。麝香酮的生物半衰期(九小时)较长,因此在剂量和服药间隔时间应于考虑。 In this paper, the in vivo kinetics study of the main aromatic component of musk, musk ketone, was marked by lanthanum in mice. The experimental result of ~3H- musk ketone single intravenous drug, its distribution half-life of 1.4 points, indicating that the drug into the body quickly distributed to the relevant organs and tissues, and quickly play a role in drug efficacy. A single oral administration of its absorption half-life of 12.6 points, indicating rapid absorption, in order to elucidate aromatherapy, and to provide a certain theoretical basis for acute illness. Musk ketones have a longer biological half-life (9 hours) and therefore should be considered at dose and dosing intervals.
