Qualitative and Quantitative Investigation of Essential Oil Compositions of Mentha Aquatica at Different Growth Stages

Plant essential oils are useful compounds that have different applications and are used in a wide range of health and pharmaceutical industries. Essential oils and their composition vary among different plant species and are influenced by external factors such as environment, temperature and internal factors such as growth stages . This study aimed to investigate the impact of growth stages on the compositions and amount of Mentha aquatica (Water mint) essential oils. The disinfected seeds of Water mint were placed in the dark and wet conditions for germination. Then germination, seeds were transferred to plastic pots, filled with perlite and maintained under greenhouse conditions. Plant leaves were collected at different growth stages (early and late vegetative phase). Plant essential oil was extracted by using Clevenger's apparatus by distillation with water. The composition of the essential oil was determined by GC/MS. Analysis of compounds in the essential oil extracted from Mentha Aquatica L, showedan increase in the amount of essential oil in the final stage of growth. Also the composition of the essential oil changed according to the growth stage. The obtained results showed the effect of the growth stage on the amount and composition of essential oil in the Mentha aquatic.
