Enhancing Biosynthesis of Rosmarinic Acid in Plants of the Lamiaceae Family Using Spectrally Tunable Light-Emitting Diodes

Rosmarinic acid is a phenolic compound that possesses excellent in vitro and in vivo biological activity as well as confers great economic value in different industries. Nevertheless, the development of an efficient and sustainable approach to enhance its production has been limited. Therefore, this thesis examines the influence of spectrally tunable LEDs as an eliciting strategy on the phenolic compound, antioxidant potential including rosmarinic acid, and the specific enzyme activity of its regulating enzyme of selected Lamiaceae species, i.e., Rosmarinus officinalis, Origanum vulgare, Salvia officinalis and Melissa officinalis.
