三种新的三萜类化合物和两种新的马兜铃醇倍半萜类化合物,即(24E)-3β-羟基葫芦-5,24-二烯-26-油酸(1)、(24E)-3,4-secocucurbita-4,24-二烯-3,26-二酸(4), (24E)-3,4-secocucurbita-4,24-二烯-3,26,29-三酸 (5)、rulepidadiol (6) 和rulepidatriol (7) 是从担子菌 Russula lepida 的子实体中分离出来的。它们的结构是通过光谱方法建立的。酸 4 和 5 是天然存在的 sec-ring-A 葫芦烷三萜类化合物的第一个例子。醇6和醇7属于马兜铃烷型倍半萜类化合物,在自然界中是一种相当罕见的类型,尤其是在真菌物种中。
Three new triterpenoids and two new aristolane sesquiterpenoids, namely (24E)‐3β‐hydroxycucurbita‐5,24‐diene‐26‐oic acid (1), (24E)‐3,4‐secocucurbita‐4,24‐diene‐3,26‐dioic acid (4), (24E)‐3,4‐secocucurbita‐4,24‐diene‐3,26,29‐trioic acid (5), rulepidadiol (6), and rulepidatriol (7), were isolated from the fruiting bodies of BasidiomycetesRussula lepida. Their structures were established by spectral methods. Acids4, and5are the first examples of naturally occurring seco‐ring‐A cucurbitane triterpenoids. Alcohols6and7, belonging to the aristolane‐type sesquiterpenoids, are of a type rather rare in nature, especially among fungal species.
