Abstract The investigation of 11 South African Helichrysum species afforded in addition to known compounds 26 further phloroglucinol derivatives, nine diterpenes, a derivative of isocomene and an α-pyrone derivative. The structures were elucidated by highfield NMR spectroscopy and a few chemical transformations. Furthermore the structures of several phloroglucinol derivatives were established by synthesis
摘要 对 11 种南非蜡菊的研究提供了除已知化合物之外的 26 种间苯三酚衍生物、9 种二萜、一种异戊二烯衍生物和一种 α-吡喃酮衍生物。通过高场核磁共振光谱和一些化学转化阐明了结构。此外,通过合成建立了几种间苯三酚衍生物的结构。讨论了化学分类。
