    摘要:

    考察了SD大鼠口服灌喂给予双去甲氧基姜黄素和姜黄素药代动力学特征。将雄性SD大鼠12只随机分为2组,分别灌服双去甲氧基姜黄素和姜黄素混悬液后,于不同时间点大鼠眼底静脉丛取血,HPLC法测定血浆中双去甲氧基姜黄素和单体姜黄素的浓度,DAS 2.1.1药动学软件计算药动学参数。结果显示,双去甲氧基姜黄素和单体姜黄素的主要药动学参数Tmax为0.75 h和0.25 h;Cmax为(62.90±2.64) μg/L和(61.64±4.30) μg/L;AUC0~72 h为(281.75±3.61) μg/(L·h)和(171.79±32.18) μg/(L·h);AUC0~∞为(291.31±15.15) μg/(L·h)和(190.46±43.81) μg/(L·h)。表明双去甲氧基姜黄素和单体姜黄素相比有更好的生物利用度。

    Abstract:

    To evaluate the pharmacokinetics of bisdemethoxycurcumin(CurIII) and curcumin (CurI) in SD rats by oral administration. Twelve male rats were random divided into two groups and were orally administrated of CurIII and CurI suspension,the blood samples were collected and of CurIII and monomer CurI concentration in blood was determined by HPLC. The data were processed by DAS 2.1.1 software to calculate the pharmacokinetic parameters. The pharmacokinetic parameter of CurIII and monomer CurI were calculated as follows:Tmax 0.75 and 0.25 h,Cmax(62.90±2.64) μg/L and (61.64±4.30) μg/L,AUC0~72 h(281.75±3.61) μg/(h·L) and (171.79±32.18) μg/(h·L),AUC0~∞(291.31±15.15) μg/(h·L) and (190.46±43.81) μg/(h·L),respectively. Compared with monomer CurI,CurIII has better bioavailability.
