Opis:
Aromatic plant species present in the natural Park of Tuscany Archipelago are used as flavoring agents and spices, as dietary supplements and in cosmetics and aromatherapy. The plants are usually collected from wild stands, inducing a depletion of the natural habitat. Therefore, micropropagation of these aromatic plants can play a role in the protection of the natural ecosystem, can guarantee a massive sustainable production and can provide standardized plant materials for diverse economical purposes. The aim of this study is to compare the volatile organic compounds produced by the wild plants with those from in vitro plantlets using headspace solid phase micro-extraction (HS-SPME) followed by capillary gas-chromatography coupled to mass spectrometry (GC-MS). Typical plants of this natural area selected for this work were Calamintha nepeta L., Crithmum maritimum L., Lavandula angustifolia L., Myrtus communis L., Rosmarinus officinalis L., Salvia officinalis L. and Satureja hortensis L. Different explants were used: microcuttings with vegetative apical parts, axillary buds and internodes. Sterilization percentage, multiplication rate and shoot length, as well as root formation were measured. The volatile aromatic profiles produced from in vitro plantlets were compared with those of the wild plants, in particular for C. maritimum, R. officinalis, S. officinalis and S. hortensis. This study indicated that the micropropagation technique can represent a valid alternative to produce massive and sterile plant material characterised by the same aromatic flavour as in the wild grown plants.

Opis:
The essential oils (EOs) and static headspaces (HSs) of in vitro plantlets and callus of Mentha x piperita were characterized by GC-MS analysis. Leaves were used as explants to induce in vitro plant material. The EO yields of the in vitro biomass were much lower (0.1% v/w) than those of the parent plants (2% v/w). Many typical mint volatiles were emitted by the in vitro production, but the callus and in vitro plantelet EOs were characterized by the lack of both pulegone and menthofuran. This was an important difference between in vitro and in vivo plant material as huge amounts of pulegone and menthofuran may jeopardise the safety of mint essential oil. Regarding the other characteristic volatiles, menthone was present in reduced amounts (2%) in the in vitro plantlets and was not detected in the callus, even if it represented the main constituent of the stem and leaf EOs obtained from the cultivated mint (26% leaves; 33% stems). The M. piperita callus was characterized by menthol (9%) and menthone (2%), while the in vitro plantlet EO showed lower amounts of both these compounds in favour of piperitenone oxide (45%). Therefore, the established callus and in vitro plantlets showed peculiar aromatic profiles characterized by the lack of pulegone and menthofuran which have to be monitored in the mint oil for their toxicity.
