“…Terpineol (a mixture of α-, βand γ-terpineol) showed the highest antimicrobial activity, decreasing the germ count by 68% (p < 0.001) on average, as shown in Figure 2. (R)-(-)-Linalool, which has already been tested by us with regard to its antimicrobial activity, using another method, 8 also gave good results in the present investigation. It reduced the germ count by 53% (p < 0.001; Figure 2).…”

Five selected compounds, geraniol, (R)‐(–)‐linalool, terpineol, γ‐terpinene and 1,8‐cineole, were tested for their influence on airborne microbes when vaporized with an air washer. Terpineol and 1,8‐cineole showed the highest antimicrobial activities. The average reduction of germ count was 68% and 64%, respectively. Although γ‐terpinene gave the lowest result among the compounds investigated, the average reduction of germ count was still 40%. When water without volatile compounds was sprayed, the colony forming units increased. These results show the positive effect of selected aroma compounds on the reduction of microbes in the room.

“…Eugenol was tested for its effect on total microbial count of bacteria, yeasts and moulds in air and was found to reduce the total microbial count. Eugenol reduced the total microbial count of bacteria by 69.4% and yeasts and moulds by 58.3% [ 107 ]. The fumigant toxicity of various essential oil constituents were investigated against acaricide-susceptible, chlorfenapyr-resistant, fenpropathrin-resistant, pyridaben-resistant and abamectin-resistant strains of female red spider mites ( Tetranychus urticae Koch).…”

Eugenol is a major volatile constituent of clove essential oil obtained through hydrodistillation of mainly Eugenia caryophyllata (=Syzygium aromaticum) buds and leaves. It is a remarkably versatile molecule incorporated as a functional ingredient in numerous products and has found application in the pharmaceutical, agricultural, fragrance, flavour, cosmetic and various other industries. Its vast range of pharmacological activities has been well-researched and includes antimicrobial, anti-inflammatory, analgesic, anti-oxidant and anticancer activities, amongst others. In addition, it is widely used in agricultural applications to protect foods from micro-organisms during storage, which might have an effect on human health, and as a pesticide and fumigant. As a functional ingredient, it is included in many dental preparations and it has also been shown to enhance skin permeation of various drugs. Eugenol is considered safe as a food additive but due to the wide range of different applications, extensive use and availability of clove oil, it is pertinent to discuss the general toxicity with special reference to contact dermatitis. This review summarises the pharmacological, agricultural and other applications of eugenol with specific emphasis on mechanism of action as well as toxicity data.

“…Therefore, the development of an easy and safe way to reduce the amount of airborne microbes in places where foods are processed or people come together is required [32]. Terpenes have the potential to act as such new air disinfectants [33,34].…”

Nerolidol and its derivatives, namely cis-nerolidol, O-methyl-nerolidol, O-ethyl-nerolidol, (-)--bisabolol, trans,trans-farnesol and its main natural source cabreuva essential oil, were tested for their antimicrobial activity against airborne microbes and antifungal properties against plant pathogens. Among the tested compounds, -bisabolol was the most effective antimicrobial agent and trans,trans-farnesol showed the best antifungal activity.
