丹參多酚酸為丹參的水溶性提取物，具有清除自由基、保護腦神經(jīng)細胞、改善腦部血液循環(huán)、改善抑郁癥認知障礙、抗炎、抗腫瘤等藥理作用。相較于化學成分與藥理作用，目前對其制備工藝的研究相對較少。主要綜述丹參多酚酸的分析方法、提取純化工藝等研究進展，以期為深入研發(fā)提供參考。丹參多酚酸主要采用的分析方法有紫外分光光度法、近紅外光譜法、一測多評法、比色法等；提取工藝主要為加熱回流提取、溫浸法、滲漉法、酶法提取等；純化工藝為大孔吸附樹脂純化法、ZnCl₂沉淀法、超濾法等。

Salvianolic acid is the water soluble extract of Salvia miltiorrhiza, and it can improve the blood circulation of the brain and improve the cognitive disorder of depression, anti-inflammation, anti-tumor and so on. At present, the research on its technology is relatively less. This particle will mainly review the research progress of analytical methods, extraction and purification technology of salvianolic acids. The main analysis methods used for salvianolic acids include UV spectrophotometry, near-infrared spectroscopy, quantitative analysis of multi-components by single marker (QAMS), colorimetry and so on. The extraction process is mainly heating reflux extraction and warm soaking method, percolation method, enzymatic extraction, etc. The purification process is macroporous resin purification, ZnCl₂ precipitation method, ultrafiltration and so on.
