 **Manuka oil** is the essential oil produced by steam distillation of the leaves (with twigs). Major components of commercial New Zealand essential oils are triketones (flavesone 4%, iso-leptospermone 4%, [[https://en.wikipedia.org/wiki/Leptospermone|leptospermone]] 15%) and sesquiterpene hydrocarbons (≥60%), including [[http://www.thegoodscentscompany.com/data/rw1384491.html|calamenene]] (14%), α-cubebene (4%), α-copaene (5%), [[http://www.thegoodscentscompany.com/data/rw1054621.html|δ-cadinene]] (6%), cadina-1,4-diene (5%) and cadina-3,5-diene (4%), δ-amorphene (3%), aromadendrene (2%) and β-caryophyllene (2%). \\ **Manuka oil** is the essential oil produced by steam distillation of the leaves (with twigs).

 Among five tea tree oils (Australian tea tree, cajupute, niaouli, kanuka and manuka), manuka oil showed highest effectiveness against gram-positive bacteria and dermatophytes, but was ineffective against Candida albicans and moulds. It tourned out that the β-triketone complex (flavesone, iso-leptospermone, and leptospermone) is the active principle. \\ Among five tea tree oils (Australian tea tree, cajupute, niaouli, kanuka and manuka), manuka oil showed highest effectiveness against gram-positive bacteria and dermatophytes, but was ineffective against Candida albicans and moulds.
