en Trypanocidal Activity of Oil of the Young Leaves of <i>Nepeta cataria</i> L. Obtained by Solvent Extraction فارماكوگنوزی و فارماسيوتيكس Pharmacognosy & Pharmaceutics پژوهشی Research <div dir="ltr" style="text-align: justify;"><span new="" roman="" times="">Trypanocidal activity was found in the volatile oil of the Young leaves of <i>Nepeta cataria</i> L. which has been extracted by diethyl ether and analyzed by GC and GC/MS. Four compounds in the oil of <i>N. cataria</i>, representing 97.53% of the oil were identified. The oil was enriched of monoterpenes with &alpha;- citral (51.95%) as the major compound. Other main compounds were &beta;- citronellol (9.03%), geraniol (4.31%) and nerol (32.24%). Nepetalactone was not detected in that oil.</span></div> <div style="text-align: justify;"><span new="" roman="" style="FONT-FAMILY: " times="">Trypanocidal activity was found in the volatile oil of the Young leaves of <i>Nepeta cataria</i> L. which has been extracted by diethyl ether and analyzed by GC and GC/MS.
