摘  要:目的:研究喉咽清口服液膜滤前后齐墩果酸-28-O-β-D吡喃葡萄糖苷在大鼠体内的药代动力学特征。方法血浆样品经乙腈处理,采用HPLC法测定血药浓度,色谱柱:C18(250 mm×4.6 mm),流动相:乙腈:0.4%磷酸(34:66),流速:1.0 mL/min,检测波长:203 nm。采用DAS 2.1药代动力学软件拟合处理,计算齐墩果酸-28-O-β-D吡喃葡萄糖苷的主要药代动力学参数。结果齐墩果酸-28-O-β-D吡喃葡萄糖苷在0.0025~0.0500μg/mL范围内线性关系良好(r=0.9991),回收率为87.72%~90.37%。喉咽清口服液膜滤前后,齐墩果酸-28-O-β-D吡喃葡萄糖苷的体内过程均符合一房室模型,Tmax分别为(1.002±0.009)、(1.002±0.006)h;Cmax分别为(0.5006±0.1080),(0.4932±0.1210)μg/L;t1/2α分别为(2.159±0.012),(2.312±0.009)h;A UC(0-6)分别为(1.338±0.031),(1.312±0.046)μg/(L·h);A UC(0-6)分别为(2.181±0.042),(2.161±0.050)μg/(L·h)。结论喉咽清口服液膜滤前后,齐墩果酸-28-O-β-D吡喃葡萄糖苷在体内的吸收及生物利用度无显著性变化。Objective To study the pharmacokinetic characteristics of Oleanolic acid-28-O-β-D-glucopyranoside be-fore and after the membrane filtration in Houyanqing Oral Liquids in rats. Methods The plasma samples were pretreat-ed by acetonitrile, then drug concentrations were determined by HPLC method,the analytes were separated on a C18 col-umn (250 mm×4.6 mm); mobile phase: acetonitrile:0.4% phosphoric acid (34:66), the flow rate: 1 mL/min, the eluent:203 nm. The pharmacokinetic parameters were calculated by DAS 2.1. Results The linear range of Oleanolic acid-28-O-β-D-glucopyranoside was 0.0025-0.0500μg/mL (r=0. 9991), and the recovery rate was 87.72%-90.37%. The Oleano-lic acid-28-O-β-D-glucopyranoside process was conformed to the atrioventricular model in the body before and after the membrane filtration in Houyanqing Oral Liquids. Tmax were (1.002±0.009), (1.002±0.006) h; Cmax were (0.5006±0.1080), (0.4932±0.121)μg/L;t1/2αwere (2.159±0.012), (2.312±0.009) h;A UC(0-6) were (1.338±0.031), (1.312±0.046)μg/(L·h);A UC(0-∞) were (2.181±0.042), (2.161±0.050) μg/(L·h). Conclusion Before and after the membrane filtration in Houyan-qing Oral Liquids, Oleanolic acid-28-O-β-D-glucopyranoside in the body of the absorption and bioavailability doesn't significantly change.
