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.
