目的：探讨一种将中药血清药理学和电生理学技术结合的方法，并将该方法运用到中药丹参的有效成分丹参酮ⅡA磺酸钠（DS‐201）的舒血管机制研究。方法采用醇提法提取丹参有效成分，将该提取液给予小鼠灌胃，经眼球采血得到小鼠血清，用高效液相色谱法（HPLC）测定小鼠血清中DS‐201的含量，并将该含药血清应用于单通道膜片钳实验，研究其对猪冠状动脉平滑肌细胞（PCASMCs）大电导钙激活钾通道（BKCa ）的作用。结果含DS‐201血清浓度线性范围是0．73～1．91μg／mL （r＝0．9977），回收率是99．85％～101．47％，血药浓度为（7．32±4．25）μg／mL ；单通道膜片钳实验结果显示小鼠含DS‐201血清对PCASMCs的BKCa有激活作用，但差异无统计学意义（P＞0．05）。结论该研究建立的提取丹参有效成分丹参酮的醇提法简单、实用、可靠，且测定DS‐201含量的HPLC方法精确；应选取高质量丹参和（或）提高丹参在体内的生物利用度，才能更好地将血清药理学和电生理学技术结合在一起。

Objective To discuss a method combining serum‐pharmacology and electrophysiology technology ,and to research the mechanism of dilating porcine coronary artery of sodium tanshinone Ⅱ‐A sulfonate (DS‐201) .Methods To give mice intragastric administration solution and measure DS‐201 concentration in mice serum ,and apply the serum to single channel patch to research its effect on big conductance calcium‐activated potassium channels(BKca ) in porcine coronary artery smooth muscle cells (PCASMCs) . Results The linear range of concentration containing DS‐201 serum was 0 .73 to 1 .91 μg/mL (r=0 .997 7) ,the recycle rate was 99 .85% -101 .47% ,and the concentration was(7 .32 ± 4 .25)μg/mL ;the result indicates that serum containing DS‐201 has activa‐tion effects on BKCa in PCASMCs ,while there was no statistical significance (P>0 .05) .Conclusion The establishment method of the alcohol extraction of Danshen is useful and reliable .The HPLC method of measuring DS‐201 concentration is precise .Choosing higher quality drugs or raising bioavailability can improve combination of the serum pharmacology and electrophysiological tech‐nique .
