摘要: 本研究提供了丹参素乙酯的合成方法。丹参水提取物在乙醇溶剂中,浓硫酸的催化下,得到了丹参素酯化产物——丹参素乙酯。实验表明,丹参素乙酯比丹参素具有更好的自由基清除能力。这种由丹参水提取物一步制备丹参素衍生物的方法简单、高效、成本低。

Abstract: A method to prepare ethyl-3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate was established.The aqueous extract of Salvia miltiorrhiza was dissolved in ethanol and concentrated sulfuric acid was added as the catalyst,and ethyl-3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate was synthesized under the reflux of ethanol.The DPPH radical elimination tests showed that ethyl-3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate had a higher radical eliminate ability compared to Danshensu.This study provided a simple,low cost but effective method to prepare Danshensu derivatives.

Key words: Danshensu, ethyl-3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate, derivative, DPPH
