assessment of characterised essential oils from Calophyllum inophyllum Linn using 2,2-diphenyl-1picrylhydrazyl and hydrogen peroxide methods', Journal of Medicinal Plants for Economic Development 4(1), a83. https://doi.org/10.4102/ jomped.v4i1.83Background: Oxidative stress is a multifactorial global health disorder that disrupts all levels of cell function. Therefore, therapeutic intervention using reliable, affordable and non-toxic natural sources is crucial. Aim:The aim of this article was to determine the chemical constituents and antioxidant activity of 10 essential oils (EOs) from Calophyllum inophyllum Linn using 2,2-diphenyl-1picrylhydrazyl (DPPH) and hydrogen peroxide (H 2 O 2 ) methods.

Introduction: Aromatic plants produce diverse chemical constituents with potential to inhibit viral infections. These plants have been utilized for the prevention and treatment of a range of infectious and non-infectious diseases. Essential oils are among the plant-derived antiviral agents that are being employed in phytomedicine, and are considered as prospective drug candidate against the ravaging Coronavirus. Methods: Relevant articles relating to the concept were identified using a combination of manual library search as well as journal publication on the subject and critically reviewed. Results: Essential oils in medicinal plants have extensive applications in medicinal chemistry, aromatherapy and pharmaceuticals. Essential oils have several biological properties such as antibacterial, antifungal, antiviral, antioxidant, anti-inflammatory, wound-healing and anti-cancer effects in vitro and in vivo. Several reports have analyzed and described essential oils as good antiviral agents against Respiratory tract viral infections hence are excellent prospective candidate against Corona virus. Conclusions: It is hoped that efficient and effective exploration and optimization of essential oils from medicinal plants would improve the drug discovery process against the ravaging Coronavirus.

Introduction: Medicinal plants have been the most productive source of leads for the development of drugs from ancient times. Current research in drug discovery involves a multifaceted approach combining botanical, biological, and molecular techniques. Medicinal plant based drug discovery continues to provide novel and important leads against several diseases. Methods: Relevant articles relating to the concept were identified using a combination of manual library search as well as journal publication on the subject and critically reviewed. Results: Drug discovery from medicinal plants continues to provide an important source of new drug leads however; numerous challenges are encountered including the procurement of plant materials and implementation of appropriate high-throughput screening bioassays. Medicinal plants have great prospect in the ultimate search for the cure against the dreaded coronavirus. Conclusion: It is hoped that the more efficient and effective application of medicinal plants would improve the drug discovery process against the dreaded coronavirus.
