A new pyrano[4,3-c][2]benzopyran-1,6-dione derivative antioxidant, named phelligridin K (1), was isolated from the methanol extract of the fruiting bodies of Fomitiporia ellipsoidea, together with the known compounds, (E)-4-(3,4-dihydroxyphenyl)but-3-en-2-one (2), hispidin (3), inoscavin C (4), and inonoblin B (5). Their structures were elucidated by means of extensive NMR and MS data analysis. Compounds 1, 4 and 5 exhibited significant scavenging activity against the ABTS radical cation.
从椭圆嗜蓝孢孔菌子实体的甲醇提取物中分离出一种新的吡喃并[4,3-c][2]苯并吡喃-1,6-二酮衍生物抗氧化剂，命名为桑黄亭K（1），同时还分离出了已知化合物（E）-4-（3,4-二羟基苯基）丁-3-烯-2-酮（2）、漆斑菌素（3）、香菇嘌呤C（4）和鬼笔环肽B（5）。通过广泛的核磁共振（NMR）和质谱（MS）数据分析阐明了它们的结构。化合物1、4和5对ABTS自由基阳离子表现出显著的清除活性。
