Evaluating the effects of kānuka essential oil (Kunzea ericoides) grown in different locations in New Zealand on two pathogenic dermatophytes: An in vitro study. American Journal of Essential Oils and Natural Products. 9(2). 28-33.2321-9114https://hdl.handle.net/10092/103618Kunzea ericoides (Kānuka) is a New Zealand (NZ) native tree. The essential oil, obtained from leaves and branches, has been commercially produced in New Zealand since the early 1990’s. Whilst there has been extensive work correctly categorising the tree, its habitat and its chemical composition little research has been undertaken on commercially produced samples of essential oil to identify chemical variations and the potential impact on commercial use. Currently most retail outlets, either within NZ or internationally, provide minimal or absent detail as to the location or recognition that geographical diversity can exist. The purpose of this study is to analyse commercially produced samples of essential oil as sold to consumers, produced indifferent geographical locations around New Zealand. These analyses, along with earlier research undertaken have identified some key differences in chemical composition, which have the potential to influence clinical applications. Kānuka oil is clearly differentiated from its relative Mānuka oil (Leptospermum scoparium) due to the high percentage of αpinene and absence of β-triketones.enAll rights reserved unless otherwise statedKānukaessential oilKunzea ericoideschemical compositionα-pineneJournal Article2022-01-20Fields of Research::42 - Health sciences::4208 - Traditional, complementary and integrative medicine::420899 - Traditional, complementary and integrative medicine not elsewhere classified
