目的 研究迷迭香Rosmarinus officinalis中的酚酸类化学成分。方法 迷迭香叶用80%乙醇提取,碱溶酸沉处理后,经硅胶柱色谱、聚酰胺柱色谱、亲脂性Sephadex LH-20柱色谱、重结晶等手段进行分离纯化,并结合多种波谱方法进行结构鉴定。结果 从迷迭香叶80%乙醇提取物中分离得9个酚酸类成分,包括一系列松香烷二萜类化合物,分别为7β-乙氧基迷迭香醌(1)、7-乙酰氧基香茶菜酚A(2)、鼠尾草酚(3)、迷迭香酚(4)、表迷迭香酚(5)、异迷迭香酚(6)、20-去氧鼠尾草酚(7)、木香醌酸(8)、桦木酸(9)。结论 化合物1和2为新化合物。

Objective To study the phenolic acids of Rosmarinus officinalis. Methods The compounds were isolated and purified from the 80% ethanol extract of leaves of R. officinalis after a process of alkali-solution and acid-isolation by several methods including silica gel column chromatography, polyamide column chromatography, lipophilic Sephadex LH-20 column chromatography, recrystal, et al. And their structures were elucidated on the basis of spectral data. Results Nine phenolic acids were isolated and identified as 7β-ethoxy rosmaqunione (1), 7-acetoxy atuntzensin A (2), carnosol (3), rosmanol (4), epirosmanol (5), isorosmanol (6), 20-deoxocarnosol (7), royleanonic acid (8) and betulinic acid (9). Conclusion Compound 1 and 2 are new compounds.
