Trypanocidal Activity of Oil of the Young Leaves of Nepeta cataria L. Obtained by Solvent Extraction
Trypanocidal activity was found in the volatile oil of the Young leaves of Nepeta cataria L. which has been extracted by diethyl ether and analyzed by GC and GC/MS. Four compounds in the oil of N. cataria, representing 97.53% of the oil were identified. The oil was enriched of monoterpenes with α- citral (51.95%) as the major compound. Other main compounds were β- citronellol (9.03%), geraniol ...
A comprehensive study on essential oils extracted from different Calamintha nepeta (L.) Savi subsp. glandulosa (Req.) Ball samples from Tarquinia (Italy) is reported. In this study, the 24-h steam distillation procedure for essential oil preparation, in terms of different harvesting and extraction times, was applied. The Gas chromatography-mass spectrometry (GC/MS) analysis showed that C. nepet...
Catmint oil and hydrogenated catmint oil were evaluated as repellents for adult Tribolium casteneum (Herbst) (Coleoptera: Tenebrionidae), the red flour beetle, and T. confusum (DuVal), the confused flour beetle, using both a traditional method of visual assessment of distribution and a video recording method to determine movement patterns of individual insects. Visual assessments of distributio...
در این بررسی تعداد 36 گونه گیاهی اسانس‌دار از تیره نعناع در مناطق مختلف استان مازندران از ارتفاع همسطح دریا تا 4000 متری مورد مطالعه قرار گرفتند. عوامل مورد تحقیق در رویشگاه‌های گونه‌ها شامل درصد شیب، جهت جغرافیایی، ارتفاع از سطح دریا، نقاط پراکنش، بافت خاک، اقلیم، متوسط بارندگی سالانه، درجه حرارت سالانه، درصد پوشش، بهترین رویشگاه از لحاظ فراوانی و تراکم، نحوه پراکنش، تیپ گیاهی، گیاهان عمده هم...
The chemical composition of Matricaria chamomilla L. and Nepeta cataria L. essential oils was determined by GC-MS on an apolar stationary phase by comparison of the characteristic fragmentation patterns with those of the Wiley 275L database. The GC-MS chromatograms were compared with those obtained by fast GC equipped with a direct resistively heated column (Ultra Fast Module 5% phenyl, 5 mx 0....
