Storability of medicinal plants plays an important role in the quantity and quality of their compounds. In order to investigate the effect of low irrigation and storability treatment on the quantitative and qualitative yield of S. Khuzestanica and S. bachtiarica essential oils, a completely random design with three replications was carried out at the Isfahan Agricultural and Natural Resources Research Center. Low irrigation treatments (16.6, 33 and 50 L/m2) were applied. Some agronomic traits and yields of essential oils and constituents of essential oils were investigated. Also, dried plants have been stored for two years, and the effect of storability on their essential oil has been investigated. According to the results, the low irrigation treatment had a significant effect on all traits except for the percentage of essential oil. The average of traits for S. khuzistanica were obtained for essential oil at 3.62%, dry matter at 1995 kg/ha, and the yield of essential oil at 71 L/ha. By reducing water (50 to 16.6 L/m2), The most important composition of the essential oil was carvacrol (95%), and treatments had no significant effect on the changing process of essential oil composition. The percentage of essential oil at harvesting compared to stored dried plants decreased (3.6 to 2.2 percent in S. khuzistanica and 2.3 to 0.8 percent in S. bachtiarica). The percentage of carvacrol in the essential oil of the stored dried plant in S. khuzistanica was 95%, and the percentage of carvacrol and p- cymen in S. bachtiarica were 41% and 34.6%, respectively.
