摘要 目的:研究两种蒙山地衣植物梅衣(Parmelia tinctorum Despr.)和小裂芽梅衣(Parmelia nimandairana A.Z.)的化学成分。方法:利用硅胶柱层析、Sephadex LH-20凝胶柱层析和高效液相等色谱技术分离纯化化学成分,通过理化性质和波谱数据确证其结构。结果:从梅衣中分离得到4个化合物:茶渍衣酸(I)、去甲环萝酸(II)、苔黑酚羧酸乙酯(III)和苔黑酚(IV);从小裂芽梅衣中分得2个化合物:松萝酸(Ⅴ)和水杨嗪酸(Ⅵ)。结论:其中,化合物Ⅴ和Ⅵ为首次从小裂牙梅衣中分离得到。 Objective : To investigate the chemical constituents of the lichen plants Parmelia tinctorum and Parmelia nimandairana collected from Meng Mountain in Shandong province. Methods: Various chromatographic techniques were used to isolate and purify the constituents and their structures were elucidated by means of spectral evidence and physiochemical properties. Results : Four compounds were isolated from Parmelia tinctorum and identified as: lecanoric acid ( I), evernic acid (II) , ethyl orsellinate (III ) and 3,5-di- hydroxytoluene (IV). Two compounds were isolated from Parmelia nimandairana and identified as: usnic acid ( V )and salazinic acid ( VI ). Conclusion : Compounds V and VI are isolated from Parmelia nimandairana for the first time.
