This study comparatively investigates the efficacy of essential oils hydrodistilled from expanded and unexpanded flowers (EF and UF) of\n                    <jats:italic>Citrus reticulata<\/jats:italic>\n                    L. in addressing ED by targeting two key enzymes: Rho\u2010kinase II (ROCK\u2010II) and PDE5A1. Gas chromatography\u2013mass spectrometry (GC\/MS) was utilized to analyze the chemical composition of these oils and revealed the presence of 35 and 40 compounds in EF and UF, respectively, across various classes. Monoterpene hydrocarbons are deemed to be the dominant class, constituting 64.33% and 71.93% of the total oil composition in EF and UF, respectively. The results highlight the significant efficacy of UF, represented by their ability to modulate ROCK\u2010II and PDE5A1 activities with IC\n                    <jats:sub>50<\/jats:sub>\n                    values of 2.64\u00a0\u00b1\u00a00.09 and 0.42\u00a0\u00b1\u00a00.015\u00a0\u00b5g\/mL, respectively, compared to sildenafil citrate (IC\n                    <jats:sub>50<\/jats:sub>\n                    \u00a0=\u00a00.97\u00a0\u00b1\u00a00.03 and 0.042\u00a0\u00b1\u00a00.001\u00a0\u00b5g\/mL). Besides, two molecular docking processes were applied to evaluate the activity of major identified volatile constituents toward PDE5A1 and ROCK\u2010II target receptors.
