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...

X-Ray crystal structures are reported for five silver(I) complexes of four monoterpenoid alkenes. Discrete mononuclear complexes of the chiral alkenes (1S)-(-)-α-pinene and (1S)(-)-β-pinene with silver perchlorate and silver hexafluorophosphate are described. The achiral diene γ-terpinene forms a discrete mononuclear adduct with silver hexafluorophosphate and a two-dimensional polymeric network...

Centella asiatica belongs to family Apiaceae is a traditionally important plant with wide range of therapeutic potential. Plant is traditionally used to treat a broad range of diseases such as diarrhea, hepatitis, measles, toothache, syphilis, leucorrhoea etc. Madecassic acid, asiatic acid, α-terpinene, α-copaene, β-caryophyllene are some of the important bioactive compounds responsible for its...

Thymus serpyllum L. grown in Kumaon region of Western Himalaya was investigated for essential oil content and composition in different seasons. The oils of fresh samples were obtained by hydrodistillation. The yield of essential oil (% v/w) during different seasons varied from 0.07 to 0.28% with the highest in summer season, at vegetative stage. The oils were analyzed by GC and GC-MS. Major com...
