Bergamot essential oil and furanocoumarins. The main compounds in the oil are limonene, linalyl acetate, linalool, γ-terpinene and β-pinene, and in smaller quantities geranial and β-bisabolene. The main non-volatile compounds are coumarins (citropten, 5-geranyloxy-7-methoxycoumarin) and furanocoumarins (bergapten, bergamottin). The bergamot essential oil is particularly subject to adulteration being an essential oil produced in relatively small quantities. Generally adulteration is to "cut" the oil, i.e. adding distilled essences of poor quality and low cost, for example of bitter orange and bergamot mint and/or mixtures of terpenes, natural or synthetic, or "reconstruct" the essence from synthetic chemicals, coloring it with chlorophyll.

HMS Bergamot (1917) HMS Bergamot (1917) HMS "Bergamot" was an "Anchusa"-class sloop of the Royal Navy, which had a short career during World War I. Built by Armstrong Whitworth, the ship was laid down on 1 January 1917, launched on 5 May, and commissioned on 14 July. Four weeks later, on 13 August 1917, under the command of Lieut-Commander Percy T. Perkins, she was sunk in the Atlantic north-west of the harbour of Killybegs by the German submarine , commanded by Walter Rohr. His war diary describes how he sighted a lone merchant ship, with no defensive armament (an unusual sight by 1917).
