Prostanthera (Lamiaceae) as a ‘Cradle of Incense’: Chemophenetics of Rare Essential Oils from Both New and Forgotten Australian ‘Mint Bush’ Species.
The highly aromatic Australian mint bushes from the genus Prostanthera Labill. produce a high yield of essential oil on hydrodistillation. Together with its rich history, horticultural potential, iconic flowers, and aromatic leaves, it achieves high ornamental and culinary value. Species in the genus express highly diverse and chemically unique essential...Sadgrove, Nicholas J. ; Padilla-González, Guillermo F. ; Telford, Ian R. H. ; Greatrex, Ben W. ; Jones, Graham L. …

The Diversity of Volatile Compounds in Australia’s Semi-Desert Genus Eremophila (Scrophulariaceae).
Australia’s endemic desert shrubs are commonly aromatic, with chemically diverse terpenes and phenylpropanoids in their headspace profiles. Species from the genus Eremophila (Scrophulariaceae ex. Myoporaceae) are the most common, with 215 recognised taxa and many more that have not yet been described, widely spread across the arid parts of the... -

GC–MS ‘chemophenetics’ on Australian pink-flowered Phebalium (Rutaceae) using herbarium leaf material demonstrates phenetic agreement with putative new species.
The aromatic pink-flowered Phebalium complex is comprised by P. nottii Maiden & Betche, P. speciosum I. Telford and the very similar but mostly white-flowered P. woombye (F.M.Bailey) Domin. Phebalium nottii, as currently circumscribed, includes several geographically disjunct populations that have been segregated at the N.C.W. Beadle Herbarium as putatively distinct...Sadgrove, Nicholas J. ; Telford, Ian R.H. ; Padilla-González, Guillermo F. ; Greatrex, Ben W. ; Bruhl, Jeremy J.

New Labdanes with Antimicrobial and Acaricidal Activity: Terpenes of Callitris and Widdringtonia (Cupressaceae)
In spite of the evidence for antimicrobial and acaricidal effects in ethnobotanical reports of Callitris and Widdringtonia, the diterpene acids from Widdringtonia have never been described and no comparison to the Australian clade sister genus Callitris has been made. The critically endangered South African Clanwilliam cedar, Widdringtonia wallichii (syn. W....Sadgrove, Nicholas J. ; Senbill, Haytham ; Van Wyk, Ben-Erik ; Greatrex, Ben W.
