“…This result agreed with Suhaj, Rácová, Polovka and Brezová (2006), who studied black pepper methanolic extract irradiated at doses ranging from 5-30 kGy. Moreover, the current results agreed with Polovka and Suhaj (2010), who reported that the highest value for the TBA of irradiated caraway samples was achieved at a dose of 10 kGy. An analysis of some irradiated edible and medicinal herb extracts at doses of 10, 20 and 30 kGy showed a change in the active components (Koseki et al, 2002).…”

“…Gamma radiation causes an increase of soluble phenols in some spice extracts (Variyar, Limaye & Sharma, 2004). On the contrary, in some studies, no significant change was observed when comparing the phenolic content in the non-irradiated samples with that of irradiated samples at a dose of 20 kGy in Agaricus blazei (Huang & Mau, 2007), 30 kGy in Rosmarinus officinalis L. powder (Perez, Calderon & Croci, 2007), and 5 to 30 kGy in Carum carvi L. and Laurus nobilis L. (Polovka & Suhaj, 2010). The total flavonoid content for thyme irradiated with a dose of 5, 10 and 15 kGy increased significantly by 43.66 ± 0.035, 47.42 ± 0.043 and 40.81 ± 0.039 mg .100 g −1 , respectively.…”

This research was undertaken to investigate the effect of gamma rays at dose rates of 5.0, 10.0 and 15.0 kGy on the chemical composition of essential oils, total antioxidants, total flavonoids and total phenols, as well as the antioxidant activity and the thiobarbituric acid (TBA) and the free radical-scavenging activity (DPPH) of thyme. Radiation processing increased the total phenols, total flavonoids and total antioxidants of thyme, and moderate changes were detected at doses of 5 and 10 kGy for the essential oils. Thymol was sensitive to irradiation, especially at 15.0 kGy doses. In addition, the evaluation of antioxidant activity using DPPH radical-scavenging activity indicated some decreases of antioxidant activity in irradiated samples, while thyme exposed to doses of 10 and 15 kGy exhibited a significant increase in TBA values. The irradiation process can facilitate the utilisation of thyme as a preservative ingredient in the food and pharmaceutical industry.

“…In particular, himachalene and germacrene were found to be the most characteristics compounds in cedar wood and cedar leaf, respectively. These findings show that the chemical compositions of essential oils vary, and are probably dependent on plant age, soil, and climatic conditions (Polovka and Suhaj, 2010 ; Kamatou et al, 2012 ).…”

Candida albicans can form biofilms composed of yeast, hyphal, and pseudohyphal elements, and C. albicans cells in the hyphal stage could be a virulence factor. The present study describes the chemical composition, antibiofilm, and antihyphal activities of cedar leaf essential oil (CLEO), which was found to possess remarkable antibiofilm activity against C. albicans but not to affect its planktonic cell growth. Nineteen components were identified in CLEO by gas chromatography/mass spectrometry, and phenolics were the main constituents. Of these, camphor, fenchone, fenchyl alcohol, α-thujone, and borneol significantly reduced C. albicans biofilm formation. Notably, treatments with CLEO, camphor, or fenchyl alcohol at 0.01% clearly inhibited hyphal formation, and this inhibition appeared to be largely responsible for their antibiofilm effects. Transcriptomic analyses indicated that camphor and fenchyl alcohol downregulated some hypha-specific and biofilm related genes (ECE1, ECE2, RBT1, and EED1). Furthermore, camphor and fenchyl alcohol reduced C. albicans virulence in a Caenorhabditis elegans nematode model. These results demonstrate CLEO, camphor, and fenchyl alcohol might be useful for controlling C. albicans infections.

“…Листья и плоды растения применяются в традиционной медицине народов разных стран для снижения высокого уровня глюкозы в крови, при лечении заболеваний вызванных грибковыми и бактериальными инфекциями. Извлечения из листьев лавра проявляют про-тивовоспалительные, успокаивающие, противоэпилептические свойства [6][7][8][9][10]. Настой из сухих листьев используют при различных желудочно-кишечных заболеваниях, а также при метеоризме в качестве ветрогонного средства [11].…”
