Abstract: (319 Views) |
Persian sage (Salvia mirzayanii L.) is a medicinal plant belonging to the mint family, which has been of interest since ancient times due to its many medicinal properties. In order to investigate the effect of different concentrations of amino acids (0, 0.5, 1 and 1.5 gr/L) and storage duration (0, 2, 4 and 6 months) on the amount and changes of Iranian sage essential oil, a factorial experiment was conducted in a randomized complete block design. Amino acid foliar application had a positive effect on the measured vegetative and reproductive traits of Iranian sage plant as well as the percentage of compounds after harvest. In this study, the most important compounds found in Iranian sage essential oil after harvesting were 5-neo-sedranol (20.11%), Lnalyl acetate (16.52%) and alphaterpinyl acetate (14.28%). The content of total phenol increased by increasing the level of amino acid foliar application up to the level of 1 mg/L (82.6 mg/L) and after that it decreased, and by continuing storage for 6 months after harvesting, it increased by 23.15% compared to four months. The highest antioxidant activity was obtained from foliar spraying of amino acid with a concentration of 1 mg/L, and storage for 6 months after harvest reduced it by 29% compared to the time of harvest. Based on the results of this study, it is recommended to use amino acid up to a concentration of 0.5 gr/L in order to achieve the maximum fresh and dry weight of the plant. |
