Volatile Terpenoids of Endophyte-free and Infected Peppermint (Mentha piperita L.): Chemical Partitioning of a Symbiosis
Microbial Ecology, 2007Co-Authors: Marco Mucciarelli, Massimo Maffei, Wanda Camusso, Paola Panicco, Carlo BicchiAbstract:The study reports the effects on volatiles of an endophytic fungus inhabiting asymptomatically the leaves of Peppermint. By means of headspace solid-phase microextraction (HS-SPME) and gaschromatography-mass spectrometry (GC-MS) terpenoids were sampled in time course from the head space of Peppermint leaves and roots. After removal of the mycelium from Peppermint tissues, fungal volatiles were analyzed and compared with those of pure fungal cultures. In the presence of the endophyte, the relative amount of all main compounds increased in leaves. Starting from the first 14 d of culture, (−)-menthone and (+)-neomenthol were consistently higher than in control plants. On the contrary, (+)-menthofuran increased only by 28 d of culture. Root volatiles were also dramatically altered by the presence of the fungus, with (+)-pulegone accounting for at least 44% of the total volatile emission. (+)-Pulegone was also the main compound of PGP-HSF mycelium isolated from Peppermint roots. The sesquiterpenoid cuparene was found as a novel compound of Peppermint leaf headspace and was a main volatile of ex planta and pure culture mycelia. The chemical spectrum of terpenoids and their distribution among Peppermint roots, leaves, and mycelia are likely to account for a fine regulation of the mutualism in planta and for the acquisition by the fungus of novel metabolic competences.

essential oil yield in Peppermint soybean strip intercropping
Field Crops Research, 2003Co-Authors: Massimo Maffei, Marco MucciarelliAbstract:In the search for sustainable agricultural methods for industrial crops, Peppermint (Menthapiperita) was strip intercropped with soybean (Glycine max). Intercropping Peppermint with soybean resulted in yield and quality increases in the essential oil, compared to sole Peppermint cultivation. The yield was higher by about 50% on an equal land area basis and higher percentages of menthol and lower percentages of menthofuran and menthyl acetate improved the quality of the oil. Intercropped Peppermint leaf number per node, leaf area, perimeter and leaf area index (LAI) were greater along with the internode length and thickness, when compared to monocultured plants. Total leaf peltate trichome number was higher in intercropped Peppermint plants and was positively correlated with greater essential oil productivity. Leaf and stem dry weight were higher in intercropped Peppermint. Total chlorophyll and carotenoid content also increased in intercropped Peppermint plants, whereas no variation was found for total soluble protein. In Peppermint, no significant differences were found in the CO2 compensation point between the two cropping systems, whereas intercropped plants showed a higher stomatal conductance at low CO2 concentration. The relationship between primary and secondary Peppermint plant metabolism was also discussed.

in vitro and in vivo Peppermint mentha piperita growth promotion by nonmycorrhizal fungal colonization
New Phytologist, 2003Co-Authors: Marco Mucciarelli, Silvano Scannerini, Cinzia M Bertea, Massimo MaffeiAbstract:Here Peppermint growth and terpene production of in vitro generated plants (Mentha piperita ) in response to inoculation with a leaf fungal endophyte were characterized. Peppermint plants were studied by means of morphometric, biochemical and image analysis, employing both in vitro and in pot cultures. Leaf essential oils were analysed by gascromatography-mass spectrometry. The endophyte induced profound effects on the growth of Peppermint, which responded with taller plants bearing more expanded leaves. The observed increase of leaf dry matter over leaf area suggested a real improvement of Peppermint metabolic and photosynthetic apparatus. Root architecture was of the herring-bone type, showing greater dry biomass percentage over the total. A sustained lowering of (+)-menthofuran and an increase of (+)-menthol percentage concentrations were found in plants from both in vitro and pot cultures. The study represents the first report on specialized endophytic fungi in Peppermint green tissues and highlights some of the principal morphological and biochemical aspects of this mutualism. Effects exerted on plant growth and essential oil production in Peppermint suggest further biotechnological applications.

commercial Peppermint mentha piperita l teas antichlamydial effect and polyphenolic composition
Food Research International, 2013Co-Authors: Karmen Kapp, Elina Hakala, Anne Orav, Leena Pohjala, Pia Vuorela, Tõnu Püssa, Heikki Vuorela, Ain RaalAbstract:Abstract The qualitative and quantitative polyphenolic contents in the infusions of the commercial Peppermint tea (Mentha × piperita L.) samples (n = 27) from different countries were studied using HPLC–UV-MS/MS analysis. The most abundant polyphenolics in the Peppermint infusion were eriocitrin, 12-hydroxyjasmonate sulfate, luteolin-O-rutinoside and rosmarinic acid. In order to evaluate the content of samples by finding chemosystematic markers, the essential oil composition was studied by GC. The analyses showed that the 24 (89%) Peppermint tea samples contained Peppermint, whereas three samples may contain Mentha spicata, different from that claimed on the package. The effects of seven Peppermint tea extracts against respiratory tract pathogen Chlamydia pneumoniae were investigated in vitro. All seven selected tea extracts were active against C. pneumoniae, the growth inhibition ranging from 20.7% to 69.5% at extract concentration of 250 μg/ml. In most cases, the antichlamydial activity was related to the Peppermint teas having also high content of luteolin and apigenin glycosides. This study supports the consumption of Peppermint tea to potentially elicit beneficial health effects on acute respiratory tract infections.

evaluation of yield essential oil content and compositions of Peppermint mentha piperita l intercropped with faba bean vicia faba l
Journal of Cleaner Production, 2018Co-Authors: Mostafa, Amani Machiani, Abdollah Javanmard, Mohammad, Reza Morshedloo, Filippo MaggiAbstract:Abstract Intercropping systems play an important role in achieving higher production and increasing the sustainability of agricultural ecosystems. In order to evaluate the quantity and quality of Peppermint essential oil and faba bean yield in intercropping systems, a two-year (2015–2016) field experiment was conducted in Iran. The study was performed with different treatments at two harvest times (July and October). The treatments were monoculture of Peppermint, monoculture of faba bean, and different ratios of Peppermint to faba bean (including 50:50, 34:66, 66:34, 40:60, 60:40, 25:75 and 75:25%). Results demonstrated that the highest Peppermint biomass yield (average of two years) was obtained in Peppermint monoculture and intercropping ratios of 66:34, 40:60, 60:40 and 75:25 in both harvests. However, the highest and the lowest essential oil content in both harvests were observed in 40:60 cropped pattern and Peppermint monoculture, respectively. In addition, the first harvest (July) gave about 20% more essential oil content than the second one (October). The highest essential oil yield in both harvests, however, was observed in 40:60 and 60:40 intercropping patterns. Furthermore, the July harvest gave approximately 52% more essential oil yield than the October harvest. At July harvest, the menthol content was enhanced in ratios of 40:60, 34:66 and 60:40 (increase of 3.3%, 2.8% and 1.8%, respectively) compare to Peppermint monoculture. In addition, all intercropping patterns in the October harvest showed a higher content of menthol than monoculture of Peppermint. According to the obtained results, intercropping of Peppermint with faba bean could improve the essential oil quality by increasing the content of menthol and decreasing the content of menthofuran and pulegone.
