 “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.” \\ “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.

 +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%). \\

 +Major components of the essential oil and pentane extract were linalyl acetate (21.4/42.0%), linalool (13.6/22.6%), 1,8-cineole (12.5/6.4%), β-myrcene (8.1/2.8%), α-terpineol (7.3/0.7%) and geranyl acetate (8.6/1.7%). Major components of the volatile aglycones were 1-octen-3-ol (40.2%), eugenol (12.2%), 3-octanol (7.0%), linalool (4.5%), benzyl alcohol (3.7%), 2-phenylethanol (3.6%), 3-hexene-1-ol (2.8%) and 1-heptene-3-ol (2.8%), but ompared with free volatile compounds (essential oil: 1.5%; pentane extract: 1.6%), the glycosidically bound volatiles were present in a lower concentration, about 0.0068%. \\

 „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).“ \\ „Mentha citrata Ehrh.
