Aerial parts of Mentha plants were collected from Sulaimaniyah city, during 15th Mar to 1st July2016. Clevenger apparatus was used for plant sample distillation and then obtained essential oils were analyzed by GC and GC/MS. The GC–MS analysis resulted in the detection of thirty-eight compounds which made up 100% of the total plant essential oil. The major components of the oil were (54.44%) of 2-Cyclohexen-1-one, 2-methyl-5-(1- methylethenyl)-, (R)-, (27.72%) of D-Limonene, (3.29%) of 2-Cyclohexen-1-ol, 2-methyl-5-(1- methylethenyl)-, trans-, (2.16%) of Cyclohexanol, 2- methyl-5-(1-methylethenyl)-, (1.83%) of Bicyclo[3.1.0] hexan-2-ol,2-methyl-5-(1-methylethyl)- (1.alpha.,2.beta.,5.alpha.) and (1.03%) of 3- Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl)-, (R)-. The significant inhibition percentages of Mentha spicata plants extract on the Aspergillus niger mycelial growth were 16.78%, 18.92%, 23.21%, 28.57% and36.78%, in 32%, 34%, 36%, 38% and 40% dilution respectively, while other concentrations showed no significant effect.

Aqueous extract of Urginea indica kunth. (Udupi acccession) was screened for antifungal activity against Fusarium oxysporum, Sclerotium rolfsii, Magnaporthe orzae, Aspergillus flavus, Alternaria alternata, Aspergillus niger and Fusarium moniliformae by poisoned food technique. The results confirmed Urginea indica extracts showed very significant antifungal activity against Fusarium oxysporum and showed significant inhibition for Sclerotium rolfsii and Magnapothea orzaea it showed no activity against Aspergillus niger and Aspergillus flavus. All the activity was evaluated to determine the lowest concentration required to inhibit visible mycelial growth of the pathogen at minmum concentration. Fusarium oxysporum showed very significant inhibition in 10% concentration (Reconfirmed) while Sclerotium showed significant inhibition in 25% concentration followed by Magnoporthe oryzae. The number of sclerotia spores formed was also reduced drastically. These results show that a potential and safe antifungal agent can be obtained from Urginea.

“Yellow moena” (Nectandra longifolia: Lauraceae) is a fragrant leaves-possessing plant commonly used for timber purposes. Nevertheless, so far, there is not available information about its chemical composition. Thus, in the present work is described the components of the essential oil from N. longifolia leaves. The oil was extracted by steam distillation and analyzed by GC/FID  and GC/MS. Twenty eight compounds were therefore identified. The main components were found to be terpinen-4-ol (53.1%), α-terpinene (6.8%), α-phellandrene (4.5%), and β-pinene (3.8%). The chemical composition of essential oil from N. longifolia leaves was consequently in agreement to that of several neotropical Lauraceae plants. In addition, the oil exhibited good antifungal activity against F. oxysporum through dose-dependent mycelial growth inhibition (using amended media and fumigant assays).

Protium ovatum is a Brazilian endemic species widely distributed between the Cerrado and Amazon biomes. Here, we evaluate the chemical composition of the essential oils (EO) of different shoot organs from P. ovatum including stems, petioles, leaves, flowers, ripe and unripe fruits, and investigate their antifungal potential against Sclerotinea sclerotiorum. The EO were obtained by hydrodistillation in a Clevenger-type apparatus and analysed by GC-MS, followed by PCA analysis. The antifungal activity was performed by agar diffusion. Fruits had the highest essential oil contents among the shoot parts. The constituents were found varyingin the different organs: α-Pinene (0.80-18.3%), β-Pinene (0.58-5.17%), Myrcene (0.52-27.3%), Limonene (3.15-59.7%), Caryophyllene E (3.67-16.4%), Germacrene D (6.34-27.4%), and δ-Cadinene (2.29-7.63%). The essential oil from ripe fruit showed the strongest antifungal activity, with the highest Inhibition of Mycelial Growth (IMG) (50.11%) at the lowest concentration assayed (18.75μg.mL-1). This is the first report on the chemical composition of the essential oils from stems, petioles, flowers, and ripe fruits of P. ovatum and their antifungal activity against S. sclerotiorum, making it a potential source of antimicrobial agents

In the present study, the chemical composition of the essential oil obtained from the aerial parts of Aaronsohnia pubescens (Desf.) K. Bremer & Humphries (Asteraceae), a chamomile-like medicinal plant, was studied. Using both GC-MS and GC-FID methods, 58 volatile compounds could be identified representing 96.6% of the total essential oil composition. The main compounds in the essential oil were monoterpene hydrocarbons such as ( Z)-β-ocimene (53.8%), myrcene (15.2%) and α-pinene (7.7%). Moreover, the essential oil of A. pubescens was tested for its antifungal activity against seven strains of phytopathogenic fungi, i.e. Aspergillus niger, A. flavus, Penicillium purpurogenum, P. jensenii, P. expansum, and Fusarium oxysporum f.sp. albedinis, using the disc diffusion method. With the exception of P. jensenii, A. pubescens essential oil demonstrated a considerable antifungal activity against all tested strains. The present results confirm the traditional use of A. pubescens as a food preservative.

There is considerable interest in the use of essential oils as alternative methods to control micromycetes from cultural heritage objects. We investigated the chemical composition and antifungal activity of the essential oil of Helichrysum italicum. The main components of the oil were ?-curcumene (22.45%), ?-pinene (15.91 %) and neryl acetate (7.85 %). H. italicum essential oil showed moderate antifungal activity against fungi isolated from cultural heritage objects. The most susceptible fungi to oil treatment were Epicoccum nigrum and Penicillium sp., while the most resistant was Trichoderma viride. The H. italicum essential oil showed demelanizing activity against Aspergillus niger.

Colloidal Silver

Colloids and especially silver are increasingly used in a variety of worldwide applications because of their potential antimicrobial activity and their plasmotic and conductivity properties. This research reports the fungitoxic properties of colloidal silver on mycelial growth of important plant pathogens: Alternaria brassicicola, Botrytis cinerea, Aspergillus flavus, Aspergillus niger, Fusarium culmorum, Fusarium oxysporum, Penicillium digitatum and Sclerotinia sclerotiorum. Although variable responses towards each compound were observed within the species the results revealed a clear reaction to limiting mycelium growth relative to various concentration of Colloidal silver (CS). Results were expressed as effective concentrations which inhibit mycelial growth by 50% and 90% respectively (EC50 and EC90). Efficiency of colloidal silver on mycelial growth inhibition of different isolates based on EC50 have the following values: 3.69 ppm for Alternaria brassicicola, 7.32 ppm for Botrytis cinerea, 18.21 ppm for Aspergillus flavus, 10.43 ppm for Aspergillus niger, 11.99 ppm for Fusarium culmorum, 12.27 ppm for Fusarium oxysporum, 10.82 ppm for Penicillium digitatum and 6.34 ppm for Sclerotinia. According to the obtained results the antifungal activity of colloidal silver particles as biocide has potential for using it as a non-aggressive treatment in horticulture and sustainable horticulture.

The essential oil of Lavandula stoechas was examined by GC and GC-MS. Discs (5 mmi.d.) of the tested fungi ( Alternaria alternata, Fusarium oxysporum and Botritys cinerea) were inoculated separately onto each assay plate and incubated at 25oC for 7 days. The oil yield of dried parts (v/dw) obtained by hydro-distillation was 2.9%. Thirty-two compounds representing 98.3% of the essential oil were determined. Linalool (49.9%), linalyl acetate (14.4%), lavandulyl acetate (5.7%), α-terpineol (5.6%), terpinene-4-ol (5.1%), lavandulol (3.7%), ( E)-β-ocimene (2.6%) and ( Z)-β-ocimene (2.4%) were identified as the main constituents of the oil. In addition, both doses of the lavender oil showed varying levels of inhibitory effects on the mycelial growth of tested fungi used in the experiment. The results demonstrated the strongest effect on B.cinerea, followed by A.alternata and F.oxysporum. The inhibitory effect is probably dependent on the concentration of essential oils.
