Furofuran lignans from the Simpson Desert species Eremophila macdonnellii.

The Eremophila plant family, which occurs in the arid zones of Australia, have witnessed extensive investigation, mostly inspired by Aboriginal traditional medicine. A wide and varied biological and phytochemical profile has been reported for over 18 individual species of Australian Eremophila, although E. macdonnellii from the Simpson Desert has not yet been investigated. Isolation and elucidation of one new and six known furofuran lignans are reported. The new lignan, epimethoxypiperitol, displayed moderate anti-cancer activity against the breast cancer cell line (MCF-7).
