standards is described for the quantitation in brain tissue of four constituents of the intoxicating beverage kava. Dihydrokawain, kawain, desmethoxyyangonin, and yangonin were administered ip to mice at a dosage of 100 mg/kg. At specific time intervals (5, 15, 30, and 45 min), the mice were sacrificed and the brain concentrations of these four compounds determined. After 5 min, dihydrokawain and kawain
描述了一种使用气相色谱-质谱法和氘代内标的技术,用于定量脑组织中醉人饮料卡瓦酒的四种成分。腹腔内给予小鼠二氢卡哇因,卡哇因,去甲氧基仰光宁和仰光宁,剂量为100 mg / kg。在特定的时间间隔(5、15、30和45分钟)处死小鼠,并测定这四种化合物的大脑浓度。5分钟后,二氢卡哇因和卡哇因的最大湿润脑组织浓度分别达到64.7 +/- 13.1和29.3 +/- 0.8 ng / mg,并迅速消除。相反,去甲氧基仰光宁和仰光宁的最大值分别对应于10.4 +/- 1.5 ng / mg和1.2 +/- 0.3 ng / mg的湿脑组织,其最大值的定义不明确,并且这些化合物从脑组织中的清除速度较慢。当以120 mg / kg的剂量腹膜内施用粗制卡瓦树脂时,相对于其单独注射所测得的值,卡哇因和仰光宁在脑中的浓度明显增加(分别为2倍和20倍)。相反,在施用粗制树脂后,二氢卡哇因和去甲氧基仰光宁保持在
