Phytochemicals from the genusLavandula: a review

The genusLavandulaoccurs naturally in the Mediterranean basin and its species are a rich source of phytochemicals. Species of this genus have attracted great interest, especially those such as fine lavender (Lavandula angustifoliaMiller) and its natural hybrid lavandin (Lavandula x intermediaEmeric ex Loisel), which are cultivated for their essential oils, widely used in perfumery and cosmetics. Peer-reviews regarding lavender volatile compounds are available, however other, non-volatile, secondary metabolites of the genusLavandulaare poorly studied. In this review, the reader will find a brief outline of the taxonomy and morphology of theLavandulagenus, along with a comprehensive description of the volatile compounds isolated or putatively identified in the genusLavandula, including triterpenoids, phenolic acids, flavonoids and benzofurans. Overall, the elaboration of a detailed list reveals that 548 specialized metabolites have been described inLavandulaspecies. This review may be used as a scientific basis for future studies on the genusLavandula, especially in chemical ecology and metabolomics where compound identification remains a limiting step.

Automated summary

The genus Lavandula naturally occurs in the Mediterranean basin and species like fine lavender and lavandin are cultivated for their essential oils. While volatile compounds in Lavandula have been well-studied, non-volatile secondary metabolites are less explored. The detailed list in this review reveals a total of 548 specialized metabolites in Lavandula species, providing a scientific foundation for future studies in chemical ecology and metabolomics.
