鳞盖红菇中一个新的倍半萜类化合物

摘要

A new aristolane sesquiterpenoid named rulepidol was isolatedfrom the fruiting body of Russula lepida Fr. Its structure was elucidated as (1aα,5α,7α,7aα,7bα)-1,1a,4,5,6,7,7a,7b-octahydro-5-hydroxy-1,1,7,7a-tetramethyl-5H-cyclopropa [α] naphthalen-2-one mainly by 1D and 2D-NMR techniques.%从鳞盖红菇（Russula lepidaFr.）的氯仿/甲醇（1∶1）部分分离得到一新化合物rulepidol（1），其结构经现代波谱技术鉴定为一aristolane型倍半萜。
