Article abstract of DOI:10.1016/S0031-9422(00)80757-8

Key Word Index - Blumea spp.; Pterocaulon virgatum; Compositae; Inuleae; sesquiterpenes; cuauthemone derivatives; thymol derivatives; himachalane derivatives; eremophilane derivative. The investigation of five Blumea species afforded, in addition to known compounds, several cuauthemone derivatives, most of them being 7,11-epoxides, some thymol derivatives, an eremophilane epoxide and a himachalane diol.From Pterocaulon virgatum a further himachalane derivative wasisolated.The structures were elucidated by spectroscopic methods and in part by partial synthesis.
