The lemon-scented volatile leaf oil of Backhousia citriodora is used in the compounding of flavours and fragrances as well as in aromatherapy. The present Australian Backhousia citriodora essential oil standard AS 4941, first published in 2001, requires significant revision in order to reflect the improved quality of presently produced oils. The reasons for the revision are not only to reflect the greater chemical uniformity of presently produced oils but also to tighten the present standard in order to prevent adulteration.
This report will be particularly useful for producers of Backhousia citriodora essential oils, but it is also relevant to producers of essential oils from other native plant species. It is also addressed to Standards Australia, as it presents information to be used in amending AS 4941–2001.
