目的：研究组分中药制剂养血注射液在大鼠体内的药代动力学。方法：配制阿魏酸、盐酸川芎嗪、丹参素钠等与处方量等比例的系列浓度混合对照品溶液，经紫外-可见分光光度法在200～600nm下全波长扫描，求算吸光度-波长曲线下面积（简称吸波面积，AUAWC），绘制药物总浓度-吸波面积的标准曲线。另大鼠尾静脉注射养血注射液，处理后的血浆经扫描获得吸波面积，将吸波面积代入线性方程，得到给药后不同时间药物总的血药浓度，通过3P97程序对血药浓度-时间数据进行房室模型拟合，获得药代动力学参数。结果：药物总浓度在0.448～14.325μg?ml-1范围内与吸波面积呈良好的线性关系，AUAWC＝5.8577C＋0.4472（r＝1.0000）。养血注射液在大鼠体内的药时过程符合一室模型，分布迅速，消除快，总药物的药代动力学参数 C0为181.55μg?ml-1，t1/2为13.1min，AUC为3432.61μg?ml-1?min。结论：吸波面积法较好地阐述了养血注射液大鼠体内的药代动力学特征，为多成分组分中药制剂的体内研究和中医药现代化与国际化奠定基础。

Objective:To study pharmacokinetics of Yangxue injection in rats. Methods:Mixed reference substance solutions of a series of concentrations were made, in which the ratio of all constituents were the same as Yangxue injection. Area under the absorbability-wavelength curve (AUAWC) was obtained through a full ultraviolet-visible spectrum scan from 200 to 600 nm wavelength. The linear relationship between AUAWC and total medicine concentration was observed. Yangxue injection was administered to rats by tail vein injection. Plasma samples were collected at different times and treated with methanol to precipitate protein.AUAWC and total medicines’ concentrations in plasma were obtained after a full ultraviolet-visible spectrum scan. The mean plasma concentration-time data was processed with 3P97 soft procedure to obtain the main pharmacokinetics parameters of total components. Results: The calibration curve was linear in the range of 0.448~14.325μg?ml-1 (r=1.0000). After intravenous injection, the pharmacokinetics behavior of Yangxue injection fitted one compartment model in rats and both the distribution and the elimination were fast. The main pharmacokinetic parameters of total components were as follows:C0 was 181.55μg?ml-1, t1/2 was 13.1min, AUC was 3432.61μg?ml-1?min. Conclusion:The pharmacokinetic characteristics of Yangxue injection in rats was shown by the method of AUAWC, which will bring a feasible idea and pathway to pharmacokinetics’ studies and modernization of TCM.
