Allo-aromadendrane- and picrotoxane-type sesquiterpenes from Dendrobium moniliforme

Eight sesquiterpenes, four stilbene derivs. along with two lignans have been isolated from lipophilic fraction of stems of Dendrobium moniliforme (Orchidaceae). Among the eight sesquiterpenes, one allo-aromadendrane-type (I) and four picrotoxane-type sesquiterpenes (e.g. II) were identified to be new compds., and alpha -dihydropicrotoxinin was isolated as a new natural product. Their structures were established on the basis of spectroscopic anal. [on SciFinder (R)]
