Antifungal activity of the carrot seed oil and its major sesquiterpene compounds.

2005

Carrot seed oil is the source of the carotane sesquiterpenes carotol, daucol and β-caryophyllene. These sesquiterpenic allelochemicals were evaluated against Alternaria alternata isolated from the surface of carrot seeds cultivar Perfekcja, a variety widely distributed in horticultural practise in Poland. Alternaria alternata is one of the most popular phytotoxic fungi infesting the carrot plant. The strongest antifungal activity was observed for the main constituent of carrot seed oil, carotol, which inhibited the radial growth of fungi by 65% at the following concentration.

Inhibitory Activity and Chemical Characterization ofDaucus carotasubsp.maximusEssential Oils

2017

The essential oils (EOs) of green seeds from Daucus carota subsp. maximus growing wild in Pantelleria Island (Sicily, Italy) were characterized. EOs were extracted by steam distillation, examined for their inhibitory properties against food-borne Gram-positive and Gram-negative bacteria and analyzed for the chemical composition by gas chromatography (GC) and mass spectrometry (MS). Undiluted EOs showed a large inhibition spectrum against Gram-positive strains and also vs. Acinetobacter spp. and Stenotrophomonas maltophilia. The minimum inhibition concentration (MIC) was in the range 1.25 – 2.50 μl/ml for the most sensitive strains. The chemical analysis indicated that D. carota subsp…

The influence of carrot seed oil and its main component carotol on development and behaviour of Aphis fabae aphids

2005

The behaviour of some aphid species is influenced by different plant odours, especially by plant essential oils, which are the mixtures of terpenes. In our study, carrot seed oil and its main sesquiterpenic component - carotol - were examined as factors influencing the behaviour and development of Aphis fabae Scop. The results of the olfaction experiments showed, that especially carrot seed oil exhibited various activities in the dose-dependent manner. When tested in the amount which did not exceed 0.01 mL of 1% v/v of suspension in water, this substance exhibited strong attractancy toward adult females of Aphis fabae. In contrast, if similar tests were carried out using > 0.1 mL of suspens…
