AIMS To compare the bacteriostatic and bactericidal activity of 13 chemotyped essential oils (EO) on 65 bacteria with varying sensitivity to antibiotics. METHODS AND RESULTS Fifty-five bacterial strains were tested with two methods used for evaluation of antimicrobial activity (CLSI recommendations): the agar dilution method and the time-killing curve method. EO containing aldehydes (Cinnamom...

The potential of different medicinal species as alternative crops for saline conditions needs to be explored. Comparative physiological responses germinating seeds and mature plants three genotypes anise (Pimpinella anisum L.), fennel (Foeniculum vulgare Mill.), ajwain (Trachyspermum ammi L.) salt were studied in a 2-year field experiment using 0 100 mcM, laboratory 0, 25, 50, 75, 100, 125 mM N...

Background: The increasing resistance to antifungal drugs and the reduced number of available drugs led to the search for therapeutic alternatives among aromatic plants and their essential oils, empirically used by antifungal effects. OBJECTIVES: The purpose of the current study was to evaluate the antifungal activity of Trachyspermum ammi essential oil (EO) against the most frequent pathogenic...

A procedure is described for the isolation of native DNA from protoplasts of ammi (Ammi visnaga) and carrot (Daucus carota) cells. Protoplasts were produced from 40 grams of fresh cells by enzyme hydrolysis and lysed with sodium dodecyl sulfate. The DNA was purified by treatment with pronase and ribonuclease. Final isolation was achieved by sucrose density gradient centrifugation.The melting te...

Linear-bilinear models, especially the additive main effects and multiplicative interaction (AMMI) model, are widely applicable to genotype-by-environment interaction (GEI) studies in plant breeding programs. These models allow a parsimonious modeling of GE interactions, retaining a small number of principal components in the analysis. However, one aspect of the AMMI model that is still debated...

The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...
