蓝柄丽齿菌的化学成分

摘要

Eight compounds have been isolated from the fruiting bodies of the basidiomycete Calodon suaveolens. Their structures were established as ergosta-7,22-dien-3β-ol (1), 5α, 8α-epidioxyergosta-6,22-dien-3β-ol (2),ergosta-5,7,22-trien-3β-ol (3),3β-hyohoxy-ergosta-5,22-dien-7-one (4),4-hydroxybenzonic acid (5),uracil (6),polyozellin (7) and (2S,3R,4E,8E,2′R)-2-N-(2′-hydroxy-palmitoyl)-1-O-β-D-gluco-pyranosyl-9-methyl-4,8-sphingadienine (8) by spectroscopic and chemical methods. All compounds are reported from this fungus for the first time.%从担子菌亚门蓝柄丽齿菌(Calodon suaveolens)中首次分离得到8个化合物,通过波谱学技术并借助必要的化学方法最终确定结构,它们是:(22E,24R)-麦角甾-7,22-二烯-3β醇(1),(22E,24R)-5α,8α-过氧麦角甾-6,22-二烯-3β-醇(2),(22E,24R)-麦角甾-5,7,22-三烯-3β-醇(3),(22E,24R)-3β-羟基麦角甾-5,22-二烯-7-酮(4),对羟基苯甲酸(5),尿嘧啶(6),polyozellin(7),(4E,8E)-2-N-(2'-羟基棕榈酰)-1-β-D-吡喃葡萄糖基-9-甲基-4,8-sphingadienine(8).
