This study aims to evaluate the benefits of some herbs such as antioxidant, antibacterial, and anti-cancer activities Lemongrass (Cymbopogon citratus), peppermint (Mentha longifolia), wormwood (Artemisia absinthium) essential oils (EOs). The chemical composition was identified using GC-MS technique. total phenolic content antioxidant were monitored by radical scavenging assay (DPPH). Furthermor...

The essential oils from twenty-two plants grown in the highlands were isolated by hydrodistillation. with an oil yield above one percent, including Achillea millefolium, Asparagus plumosus, Matricaria chamomilla, Mentha piperita, pulegium, and Thymus vulgaris, tested for antibacterial activity total antioxidant capacity. Their activities against three most common foodborne pathogens opportunist...

The characterization of essential oils of Mentha aquatica L grown in two Provinces of Vietnam was performed by means of gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) techniques. The major constituents of the essential oils were epi-bicyclosesquiphellandrene (58.9% and 52.4% respectively) and limonene (21.1% and 31.4% respectively) for Tha...

The essential oils (EOs) and static headspaces (HSs) of in vitro plantlets and callus of Mentha x piperita were characterized by GC-MS analysis. Leaves were used as explants to induce in vitro plant material. The EO yields of the in vitro biomass were much lower (0.1% v/w) than those of the parent plants (2% v/w). Many typical mint volatiles were emitted by the in vitro production, but the call...

The volatile constituents of the aerial parts of vervain (Verbena officinalis L.) cultivated locally were investigated. Analysis of the volatile fraction by GC and GC-MS is described. Compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

the volatile constituents of the aerial parts of vervain (verbena officinalis l.) cultivated locally were investigated. analysis of the volatile fraction by gc and gc-ms is described. compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

Our TLC study of the volatile oil isolated from Mentha longifolia showed a major UV active spot with higher Rf value than menthol. Based on the fact that the components of the oil from same plant differ quantitatively due to environmental conditions, the major spot was isolated using different chromatographic techniques and identified by spectroscopic means as pulegone. The presence of pulegone...

background: most of the population in the different areas of world is affected by bacterial infections responsible for dental caries. due to the importance of traditional medicines derived from herbs used for dental problems, this study investigated in vitro antibacterial activity of mentha longifolia essential oil from ardabil, iran, on streptococcus mutans, lactobacillus rhamnosus and actinom...

The volatile constituents of drug samples derived from Cannabis sativa L. were investigated by means of headspace solid phase microextraction (HS-SPME) and gas chromatography techniques (GC-MS, GC×GC-MS). Samples of cannabis herb and hashish showed clear differences in their volatile chemical profiles, mostly resulting from photo-oxidation processes occurring during the transformation of fresh ...
