Antifungal properties of some herb decoctions

Essential Oil ofSatureja calaminthasubsp.nepeta(L.) Briq. from Algeria: Analysis, Antimicrobial and Antioxidant Activities

“…The antimicrobial activity of the oil could be attributed to its high content of compounds with known antimicrobial activity, such as menthone 14 and pulegone wich is already known to exhibit an antimicrobial activity against S. aureus 15 and all the Salmonella species 16 . The oils of many species of the genus Satureja are known to possess antibacterial and fungicidal properties, Retention index relative to n-alkanes C 9 -C 16 on non polar column HP 5MS Components listed in the order of elution from HP 5MS column t = trace (< 0.1%); Percentages calculated by GC-FID on non polar HP5MS TM capillary column [17][18][19][20] .…”

The inhibitory effect of oregano extract on the growth of Aspergillus spp. and on sterigmatocystin biosynthesis

“…In this study ethanolic oregano extract inhibited the growth of A. niger and Penicillium cyclopium at a concentration of 2.5 mL/100 mL on a PDA medium, after 17 dana. Özcan and Boyraz (2000) showed that higher concentration of water oregano extract (5 mL/100 mL and 10 mL/100 mL) were needed to inhibit growth of A. parasiticus, Alternaria solani, Botrytis cinerae, F. oxysporum, Macrophomina phaseoli, and Rhizoctina solani on a PDA medium after 7 days at 24 C. On a contrary, in the study of Ş ahin et al (2004) it was found that the methanolic oregano extract did not inhibit growth of Alternaria alternata, A. flavus, Fusarium spp., Penicillium spp., using a disc diffusion method, at a concentration of 300 mg/disc on a PDA medium, after 3 days at 27 C. Numerous investigations showed that oregano essential oils exhibit stronger antifungal activity than oregano extracts. Paster et al (1995) demonstrated the antifungal activity of oregano essential oil at a concentration of 2 and 2.5 mL/L on the mycelium and spores of A. niger, A. flavus, and A. ochraceus.…”

Essential oil composition and antimicrobial activity of Origanum majorana L. extracts obtained with ethyl alcohol and supercritical carbon dioxide

“…The data refer the results of the last day of growing applying three parallel measurements to obtain the standard deviations (Janssen, Scheffer, Baerheim, & Svendsen, 1987;Kavanagh, 1963;Ö zcan & Boyraz, 2000).…”
