“…For example, the oil obtained from the ripen umbels (seeds) of Daucus carota subsp. carota growing wild in Poland (Góra et al, 2002;Staniszewska et al, 2005) and Lituania (Mockute and Nivinskiene, 2004) was characterized by high contents of ␣-pinene and sabinene; the oil of Daucus carota from Corsica has methylisoeugenol and ␣-pinene as the main compounds; the major constituent of the oil from Turkey is carotol (Ozcan and Chalchat, 2007); the seed oils of Daucus carota subsp. maximus from Lebanon have methylisoeugenol, ␤-bisabolene and ␤-asarone as the major components (Saad et al, 1995); the oil from Daucus carota subsp.…”

a b s t r a c tEthnopharmacological relevance: Essential oils are known to possess antimicrobial activity against a wide spectrum of bacteria and fungi. Daucus carota L. is used since olden times in traditional medicine, due to recognized therapeutic properties, namely the antimicrobial activity of their essential oils.Aim of the study: In the present study the composition and the antifungal activity of the oils of Daucus carota L. subsp. halophilus (Brot.) A. Pujadas (Apiaceae), an endemic plant from Portugal, were evaluated. Moreover, their cytotoxicity in mouse skin dendritic cells at concentration showing significant antifungal activity was also evaluated.Material and methods: The oils were investigated by GC and GC-MS and the antifungal activity (MIC and MLC) were evaluated against yeasts, dermatophyte and Aspergillus strains. Assessment of cell viability was made by the MTT assay.Results: The results showed large variations in the compositions during ontogenesis, particularly in the amounts of elemicin that increased significantly in the ripe umbels (5.9% vs. 31.0%). The results also demonstrated that the oil with high amounts of elemicin, which have stronger antifungal activity, showed no cytotoxic effect, at concentrations ranging from 0.16 to 0.64 l/ml, for as long as 24h.Conclusion: It is possible to find appropriate doses of Daucus carota oil showing both antifungal activity and very low detrimental effect on mammalian cells.

“…Many factors can influence the essential oil content of plants. These variations are heredity, age of the plant, climatological environment, harvesting time, fertilization and irrigation regimens, distillation procedure and isolation method (Gora et al, 2002;Omidbaigi, 1997;Reineccius, 1994).…”

The steam-distilled essential oil of Iranian black cumin seed (Nigella sativa L.) was investigated for its composition and analgesic and antiinflammatory properties. After oil analysis by GC/MS, 20 compounds were identified in the oil, obtained in 0.4% (v/w) yield. Among them, para-cymene (37.3%) and thymoquinone (13.7%) were the major components. Acetic acid-induced writhing, formalin and light tail flick tests were used for assessment of analgesic activity. Antiinflammatory activity was evaluated using carrageenan-induced paw oedema in rats and croton oil-induced ear oedema in mice. Black cumin seed essential oil (BCSEO) was found to produce a significant analgesic effect in acetic acid-induced writhing, formalin and light tail flick tests. Naloxone, an opioid antagonist, could not reverse the analgesic effect observed in the formalin test. Although oral administration of BCSEO at doses of 100, 200 and 400 micro L/kg did not exert a significant antiinflammatory effect in the carrageenan test, i.p. injection of the same doses significantly (p < 0.001) inhibited carrageenan-induced paw oedema. BCSEO at doses of 10 and 20 micro L/ear could also reduce croton oil-induced oedema. It seems that mechanism(s) other than opioid receptors is (are) involved in the analgesic effect of BCSEO since naloxone could not reverse this effect. Both systemic and local administration of BCSEO showed antiinflammatory activity. Thymoquinone, as one of the major components of BCSEO, probably has an important role in these pharmacological effects.

Aromatic plants and spices are used throughout the world for fl avouring food and beverages, as well as for food supplements, novel foods and as a source of essential oils and aromatic extracts. The non-availability or inadequacy of standards for checking and assuring the quality of aromatic plants and spices is one of the main problems that arise for industry when using such raw materials. As many aromatic plants are harvested from the wild, standardization to assure their quality is important for their safe and eff ective utilization in food and beverage industries. On the other hand, there are numerous parameters that infl uence the chemical composition of plants, which play an important role in the fi nal quality of the product and possibly in any risk arising to the consumer. Also, from a safety point of view, aromatic plants and spices should be free of undeclared contaminants and adulterants, such as toxic botanicals, pathogenic microorganisms and excessive levels of microbial toxins, pesticides or fumigation agents. We focus on these aspects and examine ways to assure their appropriate utilization from the quality and safety standpoint. The regulatory situation of medicinal and aromatic plants (MAPs) is very complicated; several diff erences in standards and regulations between countries can be found, a situation that can result in more health risks arising for consumers. To clarify some of the existing problems, the major regulations of the USA and the European Union (EU) and the borderlines between food supplements and medicines and other international standards, are briefl y described and discussed.
