制何首乌3种成分在动脉粥样硬化大鼠血浆中的测定
Determination of three constituents in Polygoni multiflori Radix Praeparata in plasma of atherosclerosis rats
摘要
Abstract
AIM To establish an HPLC method for determining the contents of three constituents in Polygoni multiflori Radix Praeparata in plasma of atherosclerosis rats.METHODS After the rats were intragastrically administrated with Polygoni multiflori Radix Praeparata CMC-Na solution,the plasma was collected.The HPLC analysis was carried out on a 30 ℃ thermostatic Hypersil C1s column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.03% phosphoric acid flowing at 0.9 mL/min in a gradient elution manner,and the detection wavelength was set at 280 nm.DAS2.0 software was applied to drawing concentration-time curves and calculating pharmacokinetic parameters.RESULTS Stilbene glucoside,emodin and physcion showed good linear relationships within the ranges of 61.25-6 125 μg/L (r =0.999 8),12.6-3 150 μg/L (r =0.999 3) and 24.1-6 030 μg/L (r =0.999 5),respectively.The method recoveries were 99.5%-105.8% with the RSDs of 1.3%-3.3%,while the extraction recoveries were 87.2%-96.3% with the RSDs of 3.2%-5.9%.The pharmacokinetic behaviors of three constituents all accorded with two-compartment model,but their contents in plasma were much lower than those in medicinal material.CONCLUSION The bioavailabilities of stilbene glucoside,emodin and physcion are relatively low in plasma of atherosclerosis rats,which may be related to constituents' intestinal absorption after intragastric administration with Polygoni multiflori Radix Praeparata.关键词
