 “Mentha citrata oil is a pale yellow or pale olive colored to almost water-white liquid of a sweet-herbaceous, somewhat fruity-fresh odor type; it resembles bergamot, but is distinctly more harsh in its terpenic topnotes, less rich in body, and without the oily-sweet, candy-like undertone of good bergamot oils. On the other hand, mentha citrata, oil presents a certain bergamot note without the citrus notes. This makes the oil more interesting in the lavender-fougere field. Its dryout has some resemblance to sage clary, but lacks the richness of that oil.” \\

 The strong lavender odor of the Bergamot Mint, Mentha citrata Ehrh., is due to two principal oil constituents, linalyl acetate and linalool, that make up 84-90% of the oil. \\

-"The major components of the essential oil and pentane extract were linalyl acetate (21.46%; 42.02%), linalool (13.68%; 22.66%), 1,8-cineole (12.51%; 6.40%), β-myrcene (8.10%; 2.87%), α-terpineol (7.38%; 0.73%) and geranyl acetate (8.66%; 1.76%). The major components of the volatile aglycones were 1-octen-3-ol (40.28%), eugenol (12.29%), 3-octanol (7.09%), linalool (4.59%), benzyl alcohol (3.71%), 2-phenylethanol (3.67%), 3-hexene-1-ol (2.87%) and 1-heptene-3-ol (2.88%). Compared with free volatile compounds (essentia1 oil: 1.56%; pentane extract: 1.64% ), the glycosidically bound volatiles were present in a lower concentration, about 0.0068%." \\

+Of the fourteen components representing more than 90% of the total essential oil of Mentha citrata Ehrh. plants collected in Argentina, the main compounds were linalool (23.8-35.4%) and linalyl acetate (48.7-60.9%). \\

 „Mentha citrata Ehrh. (bergamot mint; Lamiaceae) produces an essential oil containing only the acyclic monoterpenol (−)-3R-linalool and its acetate ester. A cloning strategy based upon the assumption that the responsible monoterpene synthase would resemble, in sequence, monoterpene cyclases from this plant family yielded a cDNA encoding the (−)-3R-linalool synthase. The nucleotide sequence of this monoterpene synthase is similar to those of several monoterpene cyclases from the mint (Lamiaceae) family (62–72% identity), but differs substantially from that of 3S-linalool synthase from Clarkia (41% identity; this composite gene appears to be of recent origin) and from that of 3R-linalool synthase from Artemisia (52% identity; the functional role of this gene is uncertain).“ \\
