Abstract Callosumin, callosuminin and callosumidin, three new stibenoids, were isolated from the orchid Agrostophyllum callosum which earlier afforded, besides 4-hydroxy-3,5-dimethoxybenzoic acid, 10 other structurally related stilbenoids, viz. orchinol, 6-methoxycoelonin, imbricatin, flaccidin, oxoflaccidin, isooxoflaccidin, flaccidinin, agrostophyllin, callosin and callosinin. The structures of callosumin
摘要 Callosumin、callosuminin 和callosumidin 这三种新的芪类化合物是从兰花胼胝属植物中分离得到的,除了4-羟基-3,5-二甲氧基苯甲酸外,还有10 种结构相关的芪类化合物,即。Orchinol、6-甲氧基腔孢菌素、imbricatin、flaccin、oxoflaccidin、isooxoflaccidin、flaccidin、agrostophyllin、callosin 和 callosinin。胼胝素、胼胝素和胼胝素的结构确定为2,4,6,7-四甲氧基-9,10-二氢菲、2,4,6,7-四甲氧基菲和2,7-二羟基-5-乙氧基(ax)- 6-甲氧基-9,10-二氢-5H-菲并[4,5-bcd]吡喃,分别来自光谱和化学证据。尽管在命名胼胝素时采用了系统编号系统,
