Abstract:
Polyphenolic compounds constitute one of the complex mechanisms that, depending on their atomic structure, participate simultaneously in plant development by regulating physiological processes and in defence against various pathogens[1]. The quantity of these compounds found in plants is influenced by the degree of exposure to oxidative stress, and their ability to interact with different enzymes, proteins, and molecules plays a significant role in human nutrition due to their antioxidant, anti-inflammatory, and preventive effects against cardiovascular diseases[2]. In light of these findings, the present study aims to verify the hypothesis of artificially stimulating the increase of polyphenolic compounds quantity in Ocimum Basilicum plants through the injection of copper nanoparticles. The study was conducted over a span of 30 days in an artificially illuminated greenhouse and involved two groups of plants: one treated with copper nanoparticles and the other serving as a reference. The variation in the quantity of polyphenols over time was determined by analyzing the plant extract. The morphological characterization of copper nanoparticles took place using UV-visible spectroscopy and dynamic light scattering (DLS) techniques.
