The genus Mentha (mint) belongs to the Lamiaceae family, which
includes 25 to 30 species. The species of this genus have been known for their medicinal and aromatherapeutic properties since ancient times and possess a significant economical and commercial reputation. Several
species of Mentha are widely used in culinary and traditional medicines in many parts of the world. Essential oils from Mentha
species have been commonly used as flavoring substance in beverages,
providing a “fresh-like” aroma and taste. Chemical analyses of Mentha species have yielded a number of important phytocompounds belonging to different classes, such as organic acids, flavonoids, sterols, alkaloids, lignans, hydrocarbons, fatty acids, tocopherols, proteins, free sugars, etc. Moreover, the main compounds in mints are essential oils, phenolics, and flavonoids. This review reports the available information on the present status (literature up to early 2020) of the Mentha species and summarizes the chemical constituents, traditional and culinary uses, cultivation, and biological properties. In addition, comprehensive analysis of the antibacterial studies conducted on Mentha species is represented. In effect, Mentha species have been presented here as a viable alternative source of many biological and chemically active compounds which are already known to be of great economic, pharmaceutical, and nutritional importance.

Herbs of the Umbelliferae family are popular spices valued worldwide for their many nutritional and health benefits. Herein, five chief umbelliferous fruits viz., cumin, fennel, anise, coriander and caraway were assessed for its secondary metabolites diversity along with compositional changes incurring upon roasting as analyzed via ultra-high performance liquid chromatography coupled to photodiode array and electrospray ionization mass detectors UHPLC-qToF/MS. A total of 186 metabolites were annotated, according to metabolomics society guidelines, belonging mainly to flavonoids, fatty acids and phenolic acids. Multivariate models viz., PCA, HCA and OPLS-DA were further employed to assess fruits\' heterogeneity in an untargeted manner and determine mechanistic changes in bioactive makeup post roasting viz., glycosidic cleavage, lipid degradation and Maillard reaction. Finally, the fruits\' antioxidant activity showed decline upon roasting and in correlation with its total phenolic content. This study presents the first complete map of umbelliferous fruit metabolome, compositional differences and its roasting effect.
