From the lichen Parmotrema praesorediosum, one new diphenyl peroxide, named praesordin A (1), together with four depsidones, including virensic acid (), protocetraric acid (), 8'--methylprotocetraric acid (), and furfuric acid () were purified. Their structures were chacracterized using extensive HR-ESI-MS and NMR spectroscopic methods. The isolated compounds () possessed stronger -glucosidase inhibitory activity (IC = 43.7-110.1 μM) than the standard drug acarbose (IC = 214.5 μM).
从地衣 Parmotrema praesorediosum 中分离得到一种新的二苯过氧化物，命名为 praesordin A（1），以及四种去甲二萜酮，包括 virensic acid（）、protocetraric acid（）、8'--methylprotocetraric acid（）和 furfuric acid（）。它们的结构通过 HR-ESI-MS 和 NMR 光谱方法进行了表征。分离得到的化合物（）比标准药物阿卡波糖（IC = 214.5 μM）具有更强的 -葡萄糖苷酶抑制活性（IC = 43.7-110.1 μM）。
