monomethyl esters, 2,6′-dicarboxy-6,7-dihydroxy-1(3′)-2′-pyranonyl-1,2-dihydronaphthalene and 2,3-dicarboxy-6,7-dihydroxy-1-(3′,4′-dihydroxy)-phenylnaphthalene, were isolated from the methanolic extract of aseptic cultures of the liverwort Jamesoniella autumnalis . Their structures were determined by spectroscopic analysis.
摘要 五种新的木脂素衍生物,2,3,6'-tricarboxy-6,7-dihydroxy-1(3')-2'-pyranonyl-1,2-dihydronaphthalene,其两个单甲酯,2,6'-dicarboxy- 6,7-dihydroxy-1(3')-2'-pyranonyl-1,2-dihydronaphthalene 和 2,3-dicarboxy-6,7-dihydroxy-1-(3',4'-dihydroxy)-phenylnaphthalene, 是从地衣詹姆士尼氏菌的无菌培养物的甲醇提取物中分离。它们的结构是通过光谱分析确定的。
