This study aims to evaluate the potential of Rosmarinic Acid as an inhibitor against Hepatitis E by interacting with the active site of the Tyrosine FYN protein. Computational approaches were employed to predict the molecular interactions between Rosmarinic Acid and Tyrosine FYN. The research methodology involved the use of software such as Pymol, Pyrex, Protein Plus, and the Lepinski Rule. Docking analysis was conducted using Pymol to obtain information about the binding energy between Rosmarinic Acid and Tyrosine FYN. The results of the analysis showed that Rosmarinic Acid exhibited a Binding Affinity of -8.3, -8, and -7.9, indicating a strong affinity towards the target protein. Additionally, Root Mean Square Deviation (RMSD) values of 0, 15.905, and 17.014 were used to assess the stability of the formed protein-ligand complex. Analysis using Protein Plus revealed interactions between Rosmarinic Acid and Tyrosine FYN. Furthermore, analysis using the Lepinski Rule to examine the physicochemical properties of Rosmarinic Acid indicated that the molecule had a mass of 360, 5 hydrogen bond donors, 8 hydrogen bond acceptors, a log P value of 1.76, and a molar reactivity of 89.8. These findings highlight the potential of Rosmarinic Acid as an inhibitor of Hepatitis E through its interaction with the Tyrosine FYN protein, providing a basis for the development of potential new therapies in the treatment of this disease.

Introduction: The world health organization recommends validating medicinal plants to ensure safety and efficacy. Lavandula is valued for the production of essential oil used in aromatherapy. Rosmarinus is known for its folk use as anti-oxidant and antidiabetic. This study aims to design monographs for Rosmarinus officinalis (Linn.) and Lavandula angustifolia (Linn.) cultivated, in conditions similar to their natural habitat, at Beirut Arab University botanical garden. Also screening the antioxidant activity of both plants, and assessing the antidiabetic effect of R. officinalis (Linn.). Methods: macroscopic and microscopic examination, hydrodistillation to obtain essential oils (EOs), thin layer chromatography, Gas chromatography-Mass spectrometry, and physiochemical properties of the EOs were determined. The antioxidant effect of the EOs is determined by DPPH assay. The antidiabetic effect of Rosemary EO is investigated using alloxan-induced diabetic mice. Results: the qualities of studied species are in agreement with the standards described in WHO monographs and in the British pharmacopeia. Composition of the EO produced from either Rosemary (REO) or Lavender (LEO) collected at different months showed differences. The EO of both showed significant antioxidant effects in DPPH assay (p\<0.05). In vivo investigation of the antidiabetic effect of REO showed a significant antidiabetic effect in diabetic mouse model (p\<0.05). Conclusion: both plant species and their EOs fulfilled most of standards specified by the British Pharmacopeia 2013. Rosemary collected in April (Spring) showed the best antioxidant activity. Lavender collected in September (Early Fall) showed the best antioxidant activity. REO revealed significant lowering in blood glucose level at the dose of 110 mg/kg.
