<i>Leptospermum scoparium</i> (β-triketone chemotype)

The essential oil of Leptospermum scoparium β-triketone Type is produced by distillation of the aerial parts of the β-triketone chemotype of Leptospermum scoparium.

Leptospermum scoparium grows naturally in coastal regions of south-east Australia and broadly throughout New Zealand’s North and South islands. It occurs with at least three chemotypes (Perry, 1997), one of which is high in beta -triketone content. β-triketone are a class of molecules found uncommonly in essential oils but more frequently in essential oils derived from myrtaceous species. They are structurally distinct from terpenes being derived from phloroglucinol.
