investigation of 17 Australian Helipterum species afforded 32 new sesquiterpene lactones (four germacranolides, 22 guaianolides and six eudesmanolides), a bisabolene derivative, four ent -beyerene derivatives, cembrol, an isomer of trixagol and four alkylated salicyclic acids. The structures were elucidated by high field NMR techniques. Three South African species gave no characteristic compounds.
摘要 对 17 种澳大利亚 Helipterum 物种的研究提供了 32 种新倍半萜内酯(4 种germacranolide、22 guaianolides 和 6 eudesmanoides)、一种红没药烯衍生物、四种 ent-beyerene 衍生物、cembrol、一种三恶烷醇的异构体和四种烷基化水杨酸。通过高场核磁共振技术阐明了结构。三个南非物种没有给出特征化合物。
