There are a variety of species referred to as oregano, but the genus Origanum (tribe Mentheae, Labiatae family) is characterized by a large morphological and chemical diversity: their antimicrobial activities are different from each other. It has already been found that the Origanum minutiflorum essential oil has antifungal activity during pickling and wet blue processes and its effectiveness improves with increasing concentration rates.(1)In this investigation, 1% of essential oils from three different oregano species and the oil of Foeniculum vulgare (fennel) were tested for their antimicrobial activity in parallel with 7-25% phenol and 4-chloro-3 methyl as commercial bactericides commonly used in the leather industry.The results showed that three essential oils of oregano had much stronger bactericidal activity than that of the commercial bactericide and the fennel oil. These findings suggested that these oregano essential oils could be used as bactericidal agents in leather industry.10aAntifungal Activities10aAntimicrobial Activity10aVulgare1 aBayramoglu, Eser, Eke  uhttp://apps.isiknowledge.com/InboundService.do?product=WOS&action=retrieve&SrcApp=Papers&UT=000251040400002&SID=2AFL5dnj5MCc8JPedL5&SrcAuth=mekentosj&mode=FullRecord&customersID=mekentosj&DestFail=http%253A%252F%252Faccess.isiproducts.com%252Fcustom_image02371nas a2200313   4500008004100000245011900041210006900160260000800229300001400237490000700251520137600258653002701634653001301661653001501674653002001689653004301709653001801752653002401770653002901794653002201823653001501845100002001860700001301880700002701893700001601920700001601936700002101952856008401973       2007                        eng d00aComposition and antimicrobial activity of the essential oil of Clinopodium ascendens (Jordan) Sampaio from Madeira0 aComposition and antimicrobial activity of the essential oil of C  cJan  a139–1440 v223 aClinopodium ascendens (Jordan) Sampaio [synonyms = Calamintha ascendens Jordan = C. officinalis Moench ssp. ascendens (Jord.) Mateo = C. sylvatica Bromf. ssp. ascendens (Jord.) P.W. Ball] is a small herbaceous plant with a very strong and distinctive mint aroma. The plant is known for its medical uses in folk medicine and as a spice in Italian kitchens. In Madeira Island, Clinopodium ascendens, known locally as 'neveda', grows wild along the shady paths of the Laurissilva forest. The local population uses the leaves of calamint as a mouth freshener and to alleviate headache and toothache. The essential oil obtained by hydrodistillation of the aerial parts of C. ascendens growing wild in Madeira was analysed by a combination of CC, GC, GC-MS, H-1- and C-13-NMR. The oil was dominated by C-3 oxygenated p-menthane derivatives: cis-isopulegone (75.2%), pulegone (6.9%), neoiso-isopulegol (6.0%) and trans-isopulegone (4.5%). The whole essential oil was tested against a variety of bacteria, both Gram-positive and Gram-negative, and two fungi; it exhibited remarkable activity against Escherichia coli and was active against Agrobacterium tumefasciens and Staphylococcus aureus and the phytopathogenic fungus Botrytis cinerea. It was ineffective against Streptococcus faecium, Streptococcus mutans and Candida albicans.
