分离丹参水提液，可得到D-（＋）B-（3，4-二羟基苯基）乳酸，由于它是一种游离酸，不稳定，故将其制成钠盐，称丹参素。经药理实验证明丹参素是丹参中抗心肌缺血的有效成份，丹参素可抑制血小板合成、聚集及释放TXA2等缩血管物质，提高心肌耐缺氧能力，保护心肌，增加冠脉流量 Separation of Salvia miltiorrhiza water extract, D- (+) B-(3,4-dihydroxyphenyl) lactic acid can be obtained, because it is a free acid, unstable, so it is made of sodium salt, said Danshensu. Pharmacological experiments show that Danshensu is an effective component of Danshen against myocardial ischemia. Danshensu inhibits platelet synthesis, aggregation and release of TXA2 and other vasoconstrictor substances, improves myocardial tolerance to hypoxia, protects the myocardium, and increases coronary flow
