Diurnal Variation of Essential Oil Ratio and Composition Of Some Basil Genotypes

The change of essential oil ratios and components five different basil genotypes harvested at times (00:00, 06:00, 12:00, 18:00) in day was investigated. Plants were grown under the field conditions oils plants extracted by hydro-distillation method. Identification performed GC-MS. It G5 genotype that had highest content all plant parts, regardless time day. (2.8%) obtained from dry leaves sampling made 18:00. main determined as linalool, eucalyptol, trans α-bergamotene, methyl cinnamate, α-muurolol eugenol. However, while these differed between genotypes, changes similar for some components. Linalool tended to increase mostly middle This study indicated ratio significantly according harvesting Bangladesh J. Bot. 51(4): 787-795, 2022 (December)
