-beta-ionone is the major volatile (12.30 % of total volatiles in the extract). Boronia extract has an odour that is `powerful and characteristic; it recalls that of chopped spinach and blackcurrant buds, and after partial evaporation, like that of clove buds and infusion of tea' (Penfold and Phillips, 1927). Boronia absolute has an intense floral impact, its odour is reminiscent of cassis and violet. It has a natural fruity-green freshness entwined with the character of ripening hay and sweet tea; undertones of yellow freesias
