A plant recently introduced into North America as the citrosa, Pelargonium citrosum ('Van Leenii'), has been marketed as a biological repellent against mosquitoes. Citrosa is claimed to repel mosquitoes within a 10 ft.2 (0.93 m2) area due to a continuous fragrant release of citronella oil. The total essential oil yield was 0.2 +/- 0.1% from fresh plant material. Chemical analysis by the authors...

The study was aimed to investigate essential oil chemical composition (gas chromatography/flame ionization detection [GC-FID] and gas chromatography/mass spectrometry [GC-MS]) and antioxidant (1,1-diphenyl-2-picrylhydrazyl free radical (DPPH) and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonate [ABTS] assays) and antimicrobial (Gram-positive and Gram-negative bacteria, fungi, and yeast) activi...

Essential oils (EOs) are acclaimed for their antimicrobial properties, leading to multiple applications in various fields. In this work, four aromatic plants were used, namely thyme (Thymus mastichina L.), everlasting (Helychrysum stoechas Moench), European pennyroyal (Mentha pulegium L.) and fennel (Foeniculum vulgare Mill.). Hydrodistillation was the extraction method obtained extracts compos...

Cultivation of mint timija (Mentha suaveolens subsp. timija (Briq.) Harley) constitutes a promising solution to the conservation and sustainable utilization of this Moroccan endemic and threatened species. Optimized agronomic practices require mineral and/or biological fertilizer applications. The aim of this study was to determine the effects of application of a complete (N, P, and K) mineral ...

Marjinal arazi koşullarında yürütülen bu çalışmada 2 farklı ekim zamanının (sonbahar ve ilkbahar) Tıbbi Nane (Mentha × piperita L. var. Mitcham)’nin verim kalitesi üzerine etkileri araştırılmıştır. Deneme Doğu Akdeniz’in Çukurova Bölgesinde tesadüf blokları deneme desenine göre üç tekrarlamalı olarak gerçekleştirilmiştir. Sonuçlara en yüksek bitki boyu (43 cm), taze herba verimi (12763 kg ha-1)...

Satureja calamintha nepeta (S. calamintha) has a history of successful use in the treatment bacterial and fungal diseases. The present study was designed to investigate chemical composition antioxidant antimicrobial activities essential oils extracted from wild S. (EOSS) domesticated (EOSD) for comparison purposes. Hydrodistillation used extract (EOs), while GC/MS analysis. Antioxidant activity...

Ziziphora clinopodioides is from the genus of Ziziphora and family of Lamiaceae,which grows in Iran and Turkey. This study was conducted to preserve the chemical and microbial quality of trout fish burger during storage using Ziziphora clinopodioides essential oil (ZEO) individually and in combination with nisin.  Firstly, the chemical composition of ZEO was deter...

background: the rice weevil, sitophilus oryzae and rice moth, corcyra cephalonica are major and cosmopolitan insect. adults of s. oryzae (male and female) and both larvae are insatiable feeders on a great variety of grains. objective: this study was conducted to estimate the insecticidal effect of essential oils from peppermint, mentha piperita l. and black pepper, piper nigrum l. against two m...

Background. Not all plants are capable of producing essential oil (EO). There 3.000 different plant EOs described in the world, but only 10 % them widely used by humans. In particular, perfumery and food industry use largest amount natural – 30 40 world production, respectively. A thorough study EOs, knowledge their components both chemical pharmacological sense will facilitate improvement qual...
