A metabolomics approach to volatile constituents of Satureja hortensis treated by salinity and vanillic acid based nanocomposite

Vanillic acid (VA), a plant-derived antioxidant, helps neutralize reactive oxygen species during environmental stress. To enhance its delivery to summer savory or Satureja hortensis, VA-based nanocomposites (VANCS) were synthesized via the coacervation method. This study assessed the efficacy of VA and VANCs at ۰.۰۱ mg/mL on S. hortensis under varying salt concentrations (۰, ۵۰, ۱۰۰, and ۱۵۰ mM NaCl) on quality of essential oil components of the plant. Analysis of essential oil composition was performed using GC-MS instrument. Multivariable statistics analyses of data was done by Metabo analyst software. The results revealed that VANCs were particularly effective in preserving or enhancing bioactive compound concentrations under stress conditions. Thymol and carvacrol were identified as the most effective essential oil components enhanced at stressful condition and promoted by both VA and VANCS. However, VANCS is more effective in stimulating of this compounds than VA. Whereas, the of this o amount of thymol was found to be ۴۴.۷% in control group, it reached to ۴۶.۱۱ and ۴۸.۳۱ in VA and VANCS treated groups, respectively, under ۱۰۰ mM of salinity. The thymol got high VIP score as ۱.۷ among other essential oil constituents. These findings indicate that bio-based VA nanocomposites can act as an eco-friendly approach to improve crop salt tolerance and the quality of essential oils and it have significant implications for sustainable agriculture, offering an innovative approach to enhance crop resilience in salt-affected soils.
