中文摘要:目的:考察大孔树脂在丹参毛状根培养生产丹参酮过程中的原位富集。方法:在丹参毛状根培养过程中添加大孔树脂,利用高效液相色谱法检测根内、培养液和树脂3个不同位点中3种主要丹参酮(隐丹参酮、丹参酮Ⅰ和丹参酮ⅡA)的含量。结果:在选择的3种大孔树脂(X-5,AB-8,XAD-4)中,树脂X-5对丹参毛状根培养过程中生产的丹参酮具有最好的吸附效果,吸附在树脂加入后的4 h达到平衡,最大吸附量达到1.2 mg·g-1,总丹参酮吸附率达到92.4 %。结论:大孔树脂X-5可以在丹参毛状根培养生产丹参酮的过程中有效地对丹参酮进行原位富集,简化了后续的提取分离步骤。

In situ extraction effect of macroporous resins on tanshinones in Salvia miltiorrhiza hairy root culture

Abstract:Objective: To investigate the in situ extraction effect of macroporous resins on tanshinones in Salvia miltiorrhiza hairy root. Method: Macroporous resins were added to S. miltiorrhiza hairy root culture and the contents of three major tanshinones (crypotanshinone, tanshinone Ⅰ and tanshinone ⅡA) in root, medium and resin were analyzed by HPLC. Result: The macroporous resin X-5 had the best adsorption effect on total tanshinones among three chosen resins (X-5, AB-8, XAD-4) during the S. miltiorrhiza hairy root culture. The adsorption reached equilibrium after four hours with the addition of the resin X-5. The saturation of X-5 on total tanshinones was 1.2 mg·g-1 resin and the adsorption ratio reached 92.4%. Conclusion: The macroporous resin X-5 could extract tanshinones in situ effectively during S. miltiorrhiza hairy root culture and simplify the further separation process.
