4-（3′-乙酰基-2 ′，6 ′-二羟基-5 ′-甲基苯基）-4-羟基-2-甲氧基丁酸（globoscinic acid）和5-（3′-乙酰基-2 ′，6 ′-二羟基-5 ′-甲基苯基）-3-甲氧基-2，3，4，5-四氢呋喃-2-酮（globoscin）作为光学活性差向异构体的混合物从真菌球形炭角菌（Xylaria globosa）和倒卵炭角菌（Xylaria obovata）的培养基中分离得到。介绍了它们的化学和物理结构测定及其不稳定性质。
4-(3′-Acetyl-2′,6′-dihydroxy-5′-methylphenyl)-4-hydroxy-2-methoxybutanoic acid (globoscinic acid) and 5-(3′-acetyl-2′,6′-dihydroxy-5′-methylphenyl)-3-methoxy-2,3,4,5-tetrahydrofuran-2-one (globoscin) have been isolated as mixtures of optically active epimers from the culture media of the fungus Xylaria globosa and the fungus Xylaria obovata. Their structure determination by chemical and physical methods and their labile properties are described.
