The general antifungal activity of essential oils is well documented. The advantage of essential oils is their bioactivity in the vapor phase, a characteristic that makes them attractive as possible fumigants for stored product protection. Essential oils of aerial parts of Mentha piperita and Lavendula angustifolia were obtained with hydrodistillation and oils composition identified with GC-MS. Menthanol (36.24%) and menthone (32.42%) were the major compounds of the M. piperata essential oil. The essential oil of L. angustifolia was rich in linalool (49.2%) , linalyl acetate (12.3%), Lavendul acetate (6.5%), 4-terpineol (5.9%). Fungal toxicity of the essential oils were evaluated against three pathogenic fungi (Rhizopus stolonifer, Botrytis cinerea and Aspergillus niger) in vitro. Plate assayes showed that the different concentrations of essential oils have antifungal activity against these fungi, and the essential oil of L. angustifolia showed stronger fungistatic activity. Lavendula oil exhibited complete growth inhibition of all pathogens at 1000 ppm and minimum EC50 (311.24 ppm) resulted on B. cinerea.

    • "Because of their cooling, pleasant aroma and flavor, essential oils of mint are used in perfumery, cosmetics, confectionery, and the pharmaceutical industries. The oil of M. piperita, known as peppermint oil, is widely used for headache, nerve pain, toothache, oral inflammation, joint conditions, itchiness, allergic rash, repelling mosquitoes, rheumatism, muscular pains, etc. [3] [4]. Menthol is the major constituent of the essential oil constituents of peppermint oil [5]. "

    ABSTRACT: EST sequences of M. piperita available in the public domain (NCBI) were exploited to develop SSR markers. A total of 1316 ESTs were assembled into 155 contigs and 653 singletons and of these, 110 sequences were found to contain 130 SSRs, with a frequency of 1 SSR/3.4 kb. Dinucleotide repeat SSRs were most frequent (72.3%) with the AG/CT (43.8%) repeat motif followed by AT/AT (16.2%). Primers were successfully designed for 68 SSR-containing sequences (62.0%). The 68 primers amplified 13 accessions of M. piperita and 54 produced clear amplicons of the expected size. Of these 54, 33 (61%) were found to be polymorphic among M. piperita accessions, showing from 2 to 4 alleles with an average of 2.33 alleles/SSR, and the polymorphic information content (PIC) value varied between 0.13 and 0.51 (average 0.25). All the amplified SSRs showed transferability among four different species of Mentha, with a highest in M. arvensis (87.0%) and minimum in M. citrata (37.0%). The newly developed SSRs markers were found to be useful for diversity analysis, as they successfully differentiated among species and accessions of Mentha.

After 48 hrs one loop of the colonies was transferred to 20 mL Sabouraud broth in 250 mL Erlenmeyer flasks and incubated overnight in an orbital shaker (100 rpm) at 30°C under aerobic condition. "

    ABSTRACT: Variations in quantity and quality of essential oil (EO) from the aerial parts of cultivated Mentha piperita were determined. The EO of air-dried sample was obtained by a hydrodistillation method and analyzed by a gas chromatography/mass spectrometry (GC/MS). The antifungal activity of the EO was investigated by broth microdilution methods as recommended by Clinical and Laboratory Standards Institute. A biofilm formation inhibition was measured by using an XTT reduction assay. Menthol (53.28%) was the major compound of the EO followed by Menthyl acetate (15.1%) and Menthofuran (11.18%). The EO exhibited strong antifungal activities against the examined fungi at concentrations ranging from 0.12 to 8.0 μ L/mL. In addition, the EO inhibited the biofilm formation of Candida albicans and C. dubliniensis at concentrations up to 2 μ L/mL. Considering the wide range of the antifungal activities of the examined EO, it might be potentially used in the management of fungal infections or in the extension of the shelf life of food products.

    ABSTRACT: The terpenoids, or isoprenoids, are a large family of natural products that are best known as constituents of the essential oils in plants. Because of their pleasant flavor and aromatic properties, essential oils have an economic importance in perfumery, cosmetic, pharmaceutical and various other industries. However, expression profiles of regulatory genes in essential oil production have not been dissected entirely, which may be an interesting topic of future research. In this report, we review recent studies on isoprenoids biosynthesis in plants. We also discuss the progress of our recent research activities on isoprenoid studies.
