“…In general, if compared to that of the thyme essential oil, the antifungal bioactivity of P. capitatum proved to be slightly lower; only for M. grisea, the activities were dramatically different. The weak biological activity of P. capitatum essential oil against fungi is, in part, confirmed by literature, i.e., the antimicrobial activity of volatile constituents was found comparable to that of most active essential oils only after long exposure [27].…”

“…M. grisea exhibited no remarkable growth inhibition at all tested doses, but showed an interesting depigmentation of the mycelium at a dose of 10 ml (data not shown), probably related to functional interaction (disruption?) of cell membranes and cell walls as reported in [27]. In general, if compared to that of the thyme essential oil, the antifungal bioactivity of P. capitatum proved to be slightly lower; only for M. grisea, the activities were dramatically different.…”

Chemical fingerprinting of commercial Pelargonium capitatum (Geraniaceae) essential oil samples of south African origin was performed by GC, GC/MS, and (13) C- and (1) H-NMR. Thirty-seven compounds were identified, among which citronellol (32.71%) and geraniol (19.58%) were the most abundant. NMR Spectra of characteristic chemicals were provided. Broad-spectrum bioactivity properties of the oil were evaluated and compared with those of commercial Thymus vulgaris essential oil with the aim to obtain a functional profile in terms of efficacy and safety. P. capitatum essential oil provides a good performance as antimicrobial, with particular efficacy against Candida albicans strains. Antifungal activity performed against dermatophyte and phytopathogen strains revealed the latter as more sensitive, while antibacterial activity was not remarkable against both Gram-positive and Gram-negative bacteria. P. capitatum oil provided a lower antioxidant activity (IC(50) ) than that expressed by thyme essential oil, both in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and β-carotene bleaching tests. Results in photochemiluminescence (PCL) assay were negligible. To test the safety aspects of P. capitatum essential oil, mutagenic and toxicity properties were assayed by Ames test, with and without metabolic activation. Possible efficacy of P. capitatum essential oil as mutagenic protective agent against NaN(3) , 2-nitrofluorene, and 2-aminoanthracene was also assayed, providing interesting and significant antigenotoxic properties.

“…MIC and MFC values obtained in the micro-atmosphere and microdilution method for O. vulgare EO ranged from 0.1 to 2.0 mL mL ¡1 , while for R. officinalis and L. angustifolia these ranged from 10.0 to 100.0 mL mL ¡1 . Inouye et al [27] tested the antifungal activity of six EOs against Trichophyton mentagrophytes. They found MID values (mg mL ¡1 air) of 4 for oregano and 16 for lavender 16 mg mL ¡1 air.…”

The aim of the present study was to assess the antifungal and anti-toxinogenic activity of 15 essential oils (EOs) against three fungi of the genus Aspergillus (A. parasiticus KMi-227-LR, A. parasiticus KMi-220-LR and A. flavus KMi-202-LR). The minimum inhibitory doses (MIDs) of the tested essential oils and their antifungal activity were determined using the micro-atmosphere method. The original commercial essential oil samples of Jasminum officinale L., Thymus vulgaris L., Syzygium aromaticum (L.) Merrill & Perry, Rosmarinus officinalis L., Ocimum basilicum L., Eucalyptus globulus Labill., Salvia officinalis L., Citrus limon (L.) Burm, Origanum vulgare L., Lavandula angustifolia Mill., Carum carvi L., Citrus sinensis (L.) Osbeck., Zingiber officinalis Rosc., Mentha piperita L. and Cinnamomum zeylanicum Nees. (C. verum J.S.Presl.) were produced in Slovakia (Calendula a.s., Nová Ľubovňa, Slovakia). All essential oils exhibited activity against all tested strains of fungi. After 14 days of incubation, A. flavus (KMi-202-LR) showed the highest susceptibility with a growth inhibition percentage (GIP) of 18.70% to C. limon and 5.92% to C. sinensis, while A. parasiticus (KMi-220-LR) exhibited a GIP of 20.56% to J. officinale. The minimum inhibitory doses (MIDs) of EOs with the most significant activity were recorded. The best antifungal activity, using the micro-atmosphere method was found in S. aromaticum with an MID of 62.5 μL L air, T. vulgaris (MID of 62.5 μL L air) and O. vulgare (MID of 31.5 μL L air) against all tested strains. Mycotoxin production of the tested strains was evaluated by the thin layer chromatography (TLC) method. Mycotoxin production of AFB and AFG was inhibited following all treatments with C. carvi, R. officinale and S. officinale, Eucalyptus globulus L. and O. basilicum L. Essential oils exhibited a potential inhibition activity against toxic fungi, although, these affected only the production of AFB.

“…No previous reports comparing the influence of lemon grass oil and its vapor on E. coli cell morphology are available. Nevertheless, Inouye et al (2006a) reported that the vapor of oregano oil also induced lysis of the Trichophyton mentagrophytes mycelia. Morphological examination by scanning electron microscope (SEM) revealed that the cell membrane and cell wall were damaged in a dose-and timedependent manner by the action of oregano vapor, causing rupture and peeling of the cell wall, with small bulges coming from the cell membrane.…”

“…Since active compound of essential oils are highly volatile, therefore, essential oils possess high antimicrobial activity in vapor phase. Further, presence in gaseous form can better facilitate the solubilization of lipophilic monoterpenes in cell membranes thereby inflicting higher damages as compared to the liquid phase (Inouye et al, 2006a). On the basis of the microscopic analyses of the Candida cells, we have previously observed that lemon grass oil vapors are more potent than lemon grass oil for causing irreparable damage to Candida cells, probably due to better penetration and contact (Tyagi & Malik, 2010a).…”
