| Abstract | ||||
| This study investigated the physiological, biochemical, and genetic characteristics of various mint species, focusing on chlorophyll content, essential oil composition, and genetic relationships. Assessment of total chlorophyll content using SPAD revealed significant variability among species as Mentha suaveolens exhibiting the highest levels (36.6) however M. piperita had the lowest value (28.0). Essential oil analysis by GC-MS highlighted the presence of monoterpenes and sesquiterpenes in low concentrations across the species. Notably, M. piperita uniquely contained germacrene D, while M. suaveolens showed the highest amounts of β-caryophyllene. Dominant oxygenated monoterpenes were identified, with M. spicata rich in carvone (70.979%) and M. longifolia in menthol (21.851%). Genetic analysis using the ITS region yielded unique bands for all species, revealing varying degrees of genetic similarity with M. spicata and M. longifolia demonstrating the closest genetic relationship. Overall, the findings indicated a complex interplay between SAPD, essential oil composition diversity, and genetic relationships in Mentha species. | ||||
