从香毛蕨(Dryopteris fragrans)中分离到1个新的倍半萜和6个已知化合物。散粒。通过紫外、质谱、1D-NMR和2D-NMR鉴定为3- o -β- d -葡萄糖吡喃醇-11- o -β- d -葡萄糖吡喃苷(1)、二氢松木醇(2)、(E)-3-(4-羟基苯基)丙烯酸(3)、esculetin(4)、5,7-二羟基-2-羟甲基色素(5)、eriodictyol(6)和异荭草苷(7)。筛选了7个分离得到的化合物的抗真菌活性。化合物2、3、4和5对犬小孢子菌和絮状表皮菌具有明显的抑制活性。
One new sesquiterpene and six known compounds were isolated from Dryopteris fragrans (L.) Schot. They were identified as 3-O-β-D-glucopyranosylalbicanol-11-O-β-D-glucopyranoside (1), dihydroconiferylalcohol (2), (E)-3-(4-hydroxyphenyl)acrylic acid (3), esculetin (4), 5,7-dihydroxy-2-hydroxymethylchromone (5), eriodictyol (6) and isoorientin (7) by UV, MS, 1D-NMR and 2D-NMR spectroscopy. The antifungal activities of the seven isolated compounds were screened. Compounds 2, 3, 4 and 5 showed obvious activities against Microsporum canis and Epidermophyton floccosum.
