Two new phenolic compounds, methyl 2-hydroxy-4-methoxy-6-(2-oxopentyl)-benzoate (1) and 4-methoxy-6-pentyl-1,2-dihydroxybenzene (2), together with two known phenolic derivatives, were isolated from the Antarctic lichen Pertusaria dactylina (Pertusariaceae). The structures of the new compounds were determined by 1D and 2D NMR and HR-MS experiments, as well as by comparison of their data with the published values.

来自南极地衣 Pertusaria dactylina 的两种新酚类化合物

两种新的酚类化合物，即 2-羟基-4-甲氧基-6-(2-氧代戊基)-苯甲酸甲酯 (1) 和 4-甲氧基-6-戊基-1,2-二羟基苯 (2)，以及两种已知的酚类衍生物, 是从南极地衣 Pertusaria dactylina (Pertusariaceae) 中分离出来的。新化合物的结构通过一维和二维 NMR 和 HR-MS 实验，以及通过将它们的数据与公布的值进行比较来确定。
