“…Our analysis with α-TA analytical standard confirmed that such strong antifungal effect of α-TA essential oil could be attributed to the presence of high amount of α-TA and, possibly, the presence of other bioactive chemical compounds such as α-terpineol, geraniol, α-terpinene ( Table 3 ). Antimicrobial activities of α-terpineol and geraniol on different microorganisms were also described in other studies [ 66 , 67 , 68 ]. Interestingly, in our studies, Candida yeasts were generally more resistant to α-TA essential oil α-TA than fungi and dermatophytes.…”

The aim of this study was to evaluate occurrence of T. pulegioides α-terpinyl acetate chemotype, as source of natural origin α-terpinyl acetate, to determine its phytotoxic and antimicrobial features. Were investigated 131 T. pulegioides habitats. Essential oils were isolated by hydrodistillation and analyzed by GC-FID and GC-MS. Phytotoxic effect of essential oil of this chemotype on monocotyledons and dicotyledons through water and air was carried out in laboratory conditions; the broth microdilution method was used to screen essential oil effect against human pathogenic microorganisms. Results showed that α-terpinyl acetate was very rare compound in essential oil of T. pulegioides: it was found only in 35% of investigated T. pulegioides habitats. α-Terpinyl acetate (in essential oil and pure) demonstrated different behavior on investigated plants. Phytotoxic effect of α-terpinyl acetate was stronger on investigated monocotyledons than on dicotyledons. α-Terpinyl acetate essential oil inhibited seeds germination and radicles growth for high economic productivity forage grass monocotyledon Poa pratensis, but stimulated seed germination for high economic productive forage legume dicotyledon Trifolium pretense. α-Terpinyl acetate essential oil showed high antimicrobial effect against fungi and dermatophytes but lower effect against bacteria and Candida yeasts. Therefore, T. pulegioides α-terpinyl acetate chemotype could be a potential compound for developing preventive measures or/and drugs for mycosis.

“…Only small amounts of natural terpineol are extracted from essential oils as an isolate. The vast majority is produced from natural pinene by chemical synthesis or biotechnological methods [ 65 ]. Terpineol is widely used in fragrant composition (e.g., lime), household products (e.g., air fresheners, washing powders).…”

This article is devoted to some aspects of the fragrant substances of plant origin applied in the food industry and perfumery as well. Since antiquity many extractive techniques have been developed to obtain essential oils. Some of them are still applied, but new ones, like microwave or ultrasound-assisted extractions, are more and more popular and they save time and cost. Independently of the procedure, the resulting essential oils are the source of many so-called isolates. These can be applied as food additives, medicines, or can be used as starting materials for organic synthesis. Some substances exist in very small amounts in plant material so the extraction is not economically profitable but, after their chemical structures were established and synthetic procedures were developed, in some cases they are prepared on an industrial scale. The substances described below are only a small fraction of the 2000–3000 fragrant molecules used to make our life more enjoyable, either in food or perfumes. Additionally, a few examples of allelopathic fragrant compounds, present in their natural state, will be denoted and some of their biocidal features will be mentioned as an arising “green” knowledge in agriculture.

“…Its annual consumption is estimated to be approximately 9.2 tons, which represents an individual intake of 17.2 µg/kg/day in the United States of America (Tai et al 2016;Molina et al 2019c). The traditional commercial uses of α-terpineol include household products, food technology and avor preparations, but the increasing discoveries have been made regarding its bioactivities, such as antioxidant, anticancer, antinociceptive, anticonvulsant and sedative activities (Sousa et al 2020;Sales et al 2020e).…”

The number of aroma compounds obtained by biotechnological process has increased tremendously in recent years and, as a result, are now being extensively employed in order to make products more attractive for consumers. In the present review, we inten to assess the wide range of reactions are catalyzed by fungal strains in regards to biotransformation of limonene and pinene for the aroma compounds production, their production rates/maximum concentrations and their biological potential. We comprehensively summarized in this review available data (2000–2021) regarding fungal biotransformation of limonene and pinene as biotechnological processes. Over the past years, has been paid to the biotransformation processes due to mild and environmentally friendly conditions applied. This review has shown that reports on the application of the fungi as a promising source of biocatalysts, mainly for stereoselective reactions such as hydroxylation and epoxidation. Studies have demonstrated the existence of promising monoterpenes used as substrates, which could be important from an industrial standpoint since this increases their importance as starting materials for obtaining aromatic molecules new. Moreover, biological (e.g.,antioxidant, anticancer) activities attributed to some monoterpene biotransformation products are increasingly being reported, indicating that their applications may transcend food, cosmetic and pharmaceutical industry.
