摘要：

Four novel diterpenes have been isolated from the stem bark of Zuelania guidonia. These compounds are based on two novel derivations of the clerodane nucleus, the zuelanin skeleton [(rel)-18β,19α-diacetoxy-10β,17β,19β,20α-clerod-3,12,14-trien-18-19-oxide] and the isozuelanin skeleton [(rel)-18β,19α-diacetoxy-10β,17β,19β,20α-clerod-3,12,14-trien-18,19-oxide]. On the basis of spectroscopic studies and some chemical modifications the four new compounds have been identified as 2α-hydroxyzuelanin-6β-cinnamate, 6β-hydroxyzuelanin-2α-cinnamate, 2β-hydroxyzuelanin-6β-cinnamate and 2β-acetoxyisozuelanin-6β-cinnamate. © 1990.
