Rosmarinus officinalis L. is a perennial herb that belongs to the Lamiaceae family. It is used as a food flavouring agent, and well known medicinally for its powerful antimutagenic, antibacterial and chemopreventive properties. The most applicable method for extraction of essential oil is water distillation (WD) and steam distillation (SD). It is a traditional technique which is used in most in...

      The chemical composition of the essential oil obtained from the aerial parts of Laurus nobilis L. has been examined by gas chromatography (GC) and GC- mass spectrometery (MS). The main components of the oil were identified. 1,8-Cineole was the major component in the oil together with b-terpinyl acetate, terpinene-4-ol, a-pinene, b-pinene, p-cymene, linalool and ...

The synergic antioxidant activity of ?-terpinene with ?-tocopherol, its synthetic analogue 2,2,5,7,8-pentamethyl-6-chromanol (PMHC), BHT, TBHQ, and catechol was studied by measuring the O2 uptake hydroperoxide formation in stripped sunflower oil at 130 °C. Although inactive when used alone, it prolonged, a concentration-dependent manner, protecting ?-tocopherol PMHC, while had no effect on cate...

For analyzing the useful components in kanpei and natsumi, volatile as well non-volatile were analyzed using HPLC GC/MS. Kanpei natsumi juices contain free sugars organic acids which are involved imparting sweet sour flavors. Analysis of sugar content revealed that sucrose was 6.53±0.31 g/100 g 7.36±0.28 respectively. The citric acid, is an 0.99±0.04 0.87±0.06 g/100g, analysis 20 different amin...

A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations were tested in this study: 5, 7.5...

Thymus hyemalis L. and Spanish Thymus vulgaris L. shrubs are characterized by a large chemical intraspecific variability among he plants. This fact makes it difficult to detect real changes occurring in their essential oil composition during the vegetative cycle. ased on this, the clones of T. hyemalis and Spanish T. vulgaris were used in this present work to monitor seasonal variations in the ...

Higher production of secondary metabolites is one the adaptive responses to alleviate impact environmental injuries. In present investigation, these with medicinal importance induced by salinity in Carum copticum was investigated. To develop a better way for substances, callogenesis and plant regeneration were analyzed, seeds, calli, and/or regenerated seedlings exposed different concentrations...

In Morocco, extensive use, traditional practices, and climate change have seriously impacted the productivity of aromatic medicinal plants (AMP). To mitigate these adverse effects, this study aims at evaluating potential arbuscular mycorrhizal fungi (AMF), namely Rhizophagusirregularis Funneliformis mosseae, in improving biomass, essential oils (EOs), biomolecule production Thymus satureioides,...

Thyme (Thymus sp.), a medicinal plant of the family Lamiaceae, is used in traditional medicine, contains wide array medicinally active components, their great majority rather complex mixture thymol, ρ-Cymene, γ-Terpinene, β-Caryophyllen, etc. This study aimed to evaluate efficacy Thymus vulgaris extract against Fusarium oxysporum f. sp.radicis-lycopersici strain under saline conditions, assuming...
