Antimicrobial composition containing manuka oil (leptospermum scoparium) and Australian tea tree oil (melaleuca alternifolia)

摘要

A broad spectrum antimicrobial composition comprising the oils of leptospermum scoparium (LS) and melaleuca alternifolia (MA), exhibits increased antimicrobial activity than if the components are used in isolation. In order to target gram negative microbes, the proportion of MA oil in the composition should be higher than that of LS. The proportion of LS oil in the composition should be higher than that of MA, in order to target gram positive microbes The high potency fractions of LS have an RI of between 1482 and 1610, and include Flavesone, Isoleptospermone and Leptospermone. The high potency fractions of MA oil include Terpinen-4-ol, and have an RI of between 1179 and 1610, and 920 and 1142.
