ABSTRACT
In this work, biological synthesis of MgO/perlite nanocomposites (NCs) besides their effects on morphology and secondary metabolite profiles of Melissa officinalis plant organ cultures were evaluated. MgO NPs were immobilized on the surface of nanoperlite using M. officinalis extract as a capping agent. The as-synthesized MgO/perlite NCs were characterized by using FTIR, XRD, SEM, EDS and DLS. The average particle size of nanoperlite and MgO/perlite NCs was about 10 and 30â¯nm, respectively. Morphological observations showed that nanoperlite and MgO/perlite NCs had no effect on root number, as well as root and shoot length. None of the applied concentrations of perlite and MgO/perlite NCs could significantly increase the growth parameters in comparison to the control, except for 150â¯mg/L of nanoperlite which caused an increase in the shoot number. Although, the contents of chlorophyll and carotenoids were not affected, the maximum content of volatile compounds obtained at 100 of MgO/perlite NCs. Rosmarinic acid was detected in shoots, which treated with 25-100â¯mg/L of perlite and 25, 50 and 150â¯mg/L of MgO/perlite NCs. Our results provided the evidence that nanoperlite and MgO/perlite NCs at specific levels may act as a novel elicitor for in vitro biosynthesis of valuable secondary metabolites.
