Bioactivities of Volatile Components from Nepalese Artemisia Species
DFT calculations (B3LYP/6-31G*) revealed thermal decomposition of ascaridole to be energetically accessible at hydrodistillation and GC conditions, but these are spin-forbidden processes, so decomposition likely proceeds by way of homolytic peroxide bond cleavage rather than retro-Diels-Alder elimination of molecular oxygen.

Essential Oil Characterization of Thymus vulgaris from Various Geographical Locations
A cluster analysis based on the compositions of these essential oils as well as 81 additional T. vulgaris essential oils reported in the literature revealed 20 different chemotypes, which represents the first chiral analysis of T. Vulgaris monoterpenoids and a comprehensive description of the different chemotype of this flavoring agent and medicinal herb. Expand
Bioactivities and Compositional Analyses of Cinnamomum Essential Oils from Nepal: C. camphora, C. tamala, and C. glaucescens
This work examines the biological activity of essential oils of Cinnamomum camphora leaves, C. glaucescens fruit, and C. tamala root from Nepal. The oils were screened for phytotoxic activity againstExpand
Volatile constituents of Pinus roxburghii from Nepal
The bioactivity of P. roxburghii essential oil is consistent with its traditional medicinal use and exhibits anti-bacterial activity and anti-fungal activity against Aspergillus niger. Expand
Volatile analysis and antimicrobial screening of the parasitic plant Cuscuta reflexa Roxb. from Nepal
Biological screening for antimicrobial activities did not show appreciable activity against either Gram-positive (Bacillus cereus and Staphylococcus aureus) or Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. Expand
Cytotoxicity of the Essential Oil of Fennel (Foeniculum vulgare) from Tajikistan
The essential oil of fennel (Foeniculum vulgare) is rich in lipophilic secondary metabolites, which can easily cross cell membranes by free diffusion, and exhibited low cytotoxicity as compared to cytotoxic reference compounds. Expand
Anxiolytic-like effects and mechanism of (−)-myrtenol: A monoterpene alcohol
The results suggest that MYR presents anxiolytic-like activity and that effect can be mediated by GABAergic transmission. Expand
The Chemical Compositions of the Volatile Oils of Garlic (Allium sativum) and Wild Garlic (Allium vineale)
The compositions of garlic and wild garlic are consistent with their use as flavoring agents in foods as well as their uses as herbal medicines, however, quantitative differences are likely to affect the flavor and bioactivity profiles of these Allium species. Expand
Leaf essential oil composition and bioactivity of Psidium guajava from Kathmandu, Nepal
P. guajava leaf oil showed notable larvicidal activity against Chaoborus plumicornis, marginal nematicidal (Caenorhabditis elegans) and insecticidal (Drosophila melanogaster), and showed no antimicrobial or cytotoxic activity. Expand
Chemical composition, antimicrobial, and cytotoxic assessment of Mitracarpus scaber Zucc. (Rubiaceae) essential oil from southwestern Nigeria
The leaf essential oil composition of Mitracarpus scaber was determined by GC-MS and showed only marginal antibacterial activity against Bacillus cereus, marginal antifungal activity against Aspergillus niger, and marginal cytotoxic activity on MCF-7 cells. Expand
