“…In studies by country, 26 chemotypes were described for Hungary (440 samples from 88 different localities) (Tétényi et al 1975) and 10 chemotypes for Finland (527 samples from 180 different localities) (Holopainen et al 1987a). Other country-wide investigations (sample size between 20 and 40) found only four to seven chemotypes (Keskitalo et al 2001;Rohloff et al 2004;Judzentiene and Mockute 2005). In the present investigation in Bielefeld, seven already known chemotypes (b-thujone, artemisa ketone, \trans[-chysanthenyl acetate, umbellulone, camphor, b-thujone, chrysanthenone, and piperitone chemotype), which are in part very frequent in Europe (Dragland et al 2005), and two new ones [piperitol and santolina triene/unknown compound (r.t. 6.70) chemotype] were found.…”

“…The results revealed an amazing diversity of chemotypes (n = 14) compared to earlier country-wide investigations. Overall, at least 31 different pure chemotypes (categorised by the main terpene only) of T. vulgare have been described for Europe (Tétényi et al 1975;Abad et al 1995;Rohloff et al 2004;Dragland et al 2005;Judzentiene and Mockute 2005). In studies by country, 26 chemotypes were described for Hungary (440 samples from 88 different localities) (Tétényi et al 1975) and 10 chemotypes for Finland (527 samples from 180 different localities) (Holopainen et al 1987a).…”

“…is a chemically highly diverse species with a complex herbivore range and a large geographic distribution (Schmitz 1998;Keskitalo et al 2001;Judzentiene and Mockute 2005). This perennial is of Eurasian origin but has been introduced to North America, where it naturalised more than 200 years ago (Mitich 1992).…”

“…This perennial is of Eurasian origin but has been introduced to North America, where it naturalised more than 200 years ago (Mitich 1992). Common tansy is known to contain high amounts of various monoterpenoids as well as sesquiterpenoids (Keskitalo et al 2001;Rohloff et al 2004;Judzentiene and Mockute 2005), which occur in distinct compositions. Therefore, individuals can be assigned to different chemotypes according to the main terpene and distinct satellite compounds.…”

Intraspecific plant chemical diversity and its relation to herbivory

Several aromatic plant species are well known for their high intraspecific variation in terpene composition. Within these species, different chemotypes can be distinguished, which are characterised by one major metabolite and distinct satellite compounds in lower abundance. Such intraspecific differences in plant quality should have major effects on herbivorous insects but may also be partly shaped by their feeding activities. In the present study, the effects of selected Tanacetum vulgare L. chemotypes on herbivore presence and preferences were investigated, and the naturally occurring diversity of T. vulgare was explored at a small spatial scale. A distinct distribution pattern of aphids and miners was found on different chemotypes of different origin of T. vulgare, with species-specific preferences of different herbivorous species. Larvae of two generalist noctuid species performed worse on most chemotypes of T. vulgare than on other plant species. Furthermore, the specific terpene composition of T. vulgare influenced larval development of these two generalist species. The naturally occurring chemical diversity of T. vulgare plants in an area smaller than 3 km(2) was extremely high, exhibiting 14 different chemotypes. Several individual patches of T. vulgare consisted of more than one chemotype. In conclusion, the existing chemotypical pattern of T. vulgare plants leads to a species-specific distribution of herbivores but may in turn be the result of contrasting selection pressures of various specialist and generalist herbivores.

SažetakUvod: Otomikoze su površne gljivične infekcije kože spoljašnjeg ušnog kanala. Jedan od terapijskih pristupa koji postaje aktuelan u lečenju otomikoza je primena esencijalnih ulja za koja je pokazano da imaju različita biološka svojstva, među kojima je i antimikrobni efekat.Cilj: Cilj istraživanja je ispitivanje antimikotičnog dejstva esencijalnih ulja matičnjaka (Melissa officinalis), manuke (Leptospermum scoparium) i vratića (Tanacetum vulgare) na uzročnike otomikoza.Materijal i metode: Ispitivana je osetljivost 20 sojeva Candida spp. i Aspergillus spp., izabranih metodom slučajnog izbora, izolovanih iz briseva spoljašnjeg ušnog kanala bolesnika sa znacima i simptomima otitis externe. Antigljivična aktivnost esencijalnih ulja matičnjaka, manuke i vratića ispitivana je mikrodilucionom metodom, određivanjem vrednosti minimalnih inhibitornih (MIC) i minimalnih fungicidnih koncentracija (MFC).Rezultati: Vrednosti MIC matičnjaka kretale su se u rasponu od 0,39 do 50 μL/mL, manuke od 0,39 do 50 μL/mL i vratića od 1,56 do 50 μL/mL. Minimalne fungicidne koncentracije su bile 2-4 puta veće od vrednosti MIC, izuzev u slučaju jednog soja Aspergillus niger koji je bio tolerantan na esencijalno ulje matičnjaka.Zaključak: Ispitivanjem aktivnosti esencijalnih ulja matičnjaka, manuke i vratića na sojeve Candida spp. i Aspergillus spp. mikrodilucionom metodom pokazano je da navedena esencijalna ulja imaju antimikotični efekat.Ključne reči: esencijalno ulje, Melissa officinalis, Leptospermum scoparium, Tanacetum vulgare, antimikotična aktivnost Abstrast Introduction: Otomycosis is а superficial fungal infection of the external ear canal. One of the therapeutic approaches that became topical in treatment of otomycosis is the application of essential oils, which is shown to have different biological properties, including the antimicrobial effect.Aim: The objective of the research is to examine antimycotic effects of essential oils of lemon balm (Melissa officinalis), manuka (Leptospermum scoparium) and tansy (Tanacetum vulgare) on the causative agents of otomycosis. Materials and Methods:In this study, we investigated the sensitivity of 20 randomly selected strains of Candida spp. and Aspergillus spp. isolated from swabs taken from the external ear canal of patients with signs and symptoms of otitis externa. Antifungal activity of essential oils of lemon balm, manuka and tansy was tested by using the microdilution method by determining the value of the Minimum inhibitory concentration (MIC) and Minimum fungicidal concentration (MFC).Results: MIC values of lemon balm were in the range of 0.39-50 μl/ml, manuka of 0.39-50 μL/mL and tansy of 1.56-50 μL/mL. The MFC values were 2-4 times higher than the MIC values, except in the case of a strain of Aspergillus niger, which was tolerant of the lemon balm essential oil. Conclusion:The investigation has shown that essential oil activities of lemon balm, manuka and tansy to the strains of Candida spp. and Aspergillus spp, using the microdilution method, have antifungal effect.
