fa Chemical Constituents of the Essential oil of <i>Sanguisorba minor</i> Scop. Leaves, from Iran فارماكوگنوزی و فارماسيوتيكس Pharmacognosy & Pharmaceutics پژوهشی Research <div dir="ltr" style="text-align: justify;"><strong>Background:</strong> The family Rosaceae, include some large genus, eg the genus Rose includes 200 species and 18000 cultivars. <strong>Objective:</strong> Aim of this study is to determine the chemical composition of the hydrodistilled oil of the leaves of <em>Sanguisorba minor</em> scop, of Iranian origin for the first time. <strong>Methods:</strong> The essential oil obtained by hydrodistillation of <em>Sanguisorba minor</em> was analyzed by GC and GC/MS. <strong>Results:</strong> The major constituents appeared to be <em>(E, E)</em> farnesyl acetate (13.4%), nonadecane (11.2%) and docosane (11.0%). <strong>Conclusion:</strong> In <em>Sanguisorba minor</em> we identified 17 components representing 93.2%. It&rsquo;s rich in regard to aliphatic hydrocarbons (40.6%), five sesquiterpenes (36.8%), one oxygenated monoterpene (7.3%) and one aliphatic aldehyde (8.3%).</div> <div dir="ltr" style="text-align: justify;"><strong>Background:</strong> The family Rosaceae, include some large genus, eg the genus Rose includes 200 species and 18000 cultivars. <strong>Objective:</strong> Aim of this study is to determine the chemical composition of the hydrodistilled oil of the leaves of <em>Sanguisorba minor</em> scop, of Iranian origin for the first time. <strong>Methods:</strong> The essential oil obtained by hydrodistillation of <em>Sanguisorba minor</em> was analyzed by GC and GC/MS. <strong>Results:</strong> The major constituents appeared to be <em>(E, E)</em> farnesyl acetate (13.4%), nonadecane (11.2%) and docosane (11.0%). <strong>Conclusion:</strong> In <em>Sanguisorba minor</em> we identified 17 components representing 93.2%.
