Tanzanene(1)是一种螺旋型苯并吡喃倍半萜，从坦桑尼亚乌瓦里亚（Uvaria tanzaniae Verdc）的根皮中分离得到。并通过高分辨率核磁共振测定了其结构。坦桑烯的分子结构可以被认为是异芳腺烯(2)和邻羟基甲苯（6-亚甲基-2,4-环己二烯-1- 1,3）的醌类化合物的环加成产物。已知的二氢查尔酮乌瓦列素、二乌瓦列素、chamuvaretin和异三乌瓦列素也从同一株植物中分离得到。
Tanzanene (1), a spiro benzopyranyl sesquiterpene, was isolated from the rootbark of Uvaria tanzaniae Verdc. and its structure was determined by high-resolution NMR. The molecular structure of tanzanene can be thought of as a cycloaddition product of alloaromadendrene (2) and the quinone methide of o-hydroxytoluene (6-methylene-2,4-cyclohexadien-1-one, 3). The known dihydrochalcones uvaretin, diuvaretin, chamuvaretin, and isotriuvaretin were also isolated from the same plant.
