“…Irradiation treatments induce disruption of the cell wall structure and result in greater oil extractability from plant parts. These findings are consistent with Nada et al (2022), who found that γirradiation boosted the EOs of clove, with the maximum rise occurring at a dosage of 10 kGy. Moreover, Shahin et al (2019) reported that at doses of 30 kGy, irradiation processing caused an increase in clove essential oil content from 16.33% to 18.03%.…”

This study was carried out to investigate the effect of gamma-irradiation at doses of 0, 5, and 10 kGy on the essential oil constituents of clove and cinnamon; evaluate the efficacy of the extraction of essential oils from irradiated clove and cinnamon as an antimicrobial agent. Results showed that the main components of clove essential oils were eugenol (75.71%) and eugenol acetate (9.73%). The major components of cinnamon essential oils were cinnamaldehyde (75.55%). Gamma irradiation enhanced the antioxidant activity of essential oils. However, irradiation at a dose of 10 kGy was the best treatment for the antioxidant activity of clove and cinnamon essential oils. Essential oils of clove and cinnamon were tested for their antibacterial activity against four strains of S. aureus, E. coli, B. cereus, and P. aeruginosa. Results revealed that each oil tested had a growthinhibiting impact on the microorganisms under study. Gamma irradiation at a dosage of 10 kGy was more effective against microorganisms.

“…The findings of this study showed that the inhibitory effect of E. caryophylata, C. sinensis, and T. chebula Retz was higher than those of the other plants, while less than that of MTZ with IC 50 = 100 μg/mL. E. caryophylata belongs to the Myrtaceae family and has compounds such as B-caryophyllene, acetyleugenol, alpha-humulene, thymol, eugenol, cinnamaldehyde, and methyl salicylate (19). The effects of this plant (e.g., antiinflammatory, anti-epileptic, antibacterial, insecticide, antiviral, antioxidant, and anti-inflammatory activities, as well as cytotoxicity, and anesthesia) have been mentioned in some studies (20).…”

Background and aims: Trichomoniasis is the most common non-viral sexually transmitted infection worldwide; although it is treated by a 5-nitroimidazole drug family such as metronidazole (MTZ) with numerous side effects, and in this regard, alternative new drugs are required. Therefore, this study examined the anti-Trichomoniasis effect of the hydroalcoholic extract of some traditional medicinal plants of Iran in vitro. Methods: In this experimental study, the hydroalcoholic extracts of medicinal plants were prepared by maceration at a stock concentration of 20 mg/mL in the saline solution and then used for in vitro anti-trichomonas experiments. Trichomonas vaginalis trophozoites were isolated from the patient and cultured in a Trypticase Yeast extract Iron-Serum-33 medium. In addition, 200 μL of the culture medium containing 5×104 trophozoites was diluted in plate wells, and 10 doses were separately added on trophozoites for each extract serially diluted between 0.12 and 16 mg/mL in triplicate. The plates were incubated for 48 hours at 37 ° C with 5% CO2 . The number of trophozoites was counted with a hemocytometer and Trypan blue staining. Finally, the half maximal inhibitory concentration (IC50) was calculated by probit analysis. Results: Among the tested plants, Eugenia caryophyllata, Camellia sinensis, and Terminalia chebula Retz showed the best anti-trichomonal activity with IC50 values of 1.21, 1.62, and 1.66 mg/mL, respectively. All tested extracts had more IC50 than MTZ (IC50 100 mg/mL), an antiprotozoal drug used as a positive control. Conclusion: According to the results of this study, E. caryophylata, C. sinensis and T. chebula Retz affected the growth of T. vaginalis. Thus, it is recommended that other studies use this plant for the treatment of trichomoniasis infection.

“…Similar to tea tree oil, Daito- gettou EO contained a large amount of terpinen-4-ol ( Table 3 ). Generally, external effects cause changes in the ratios of the constituents of EOs [ 38 ]. The composition of gettou EOs is known to fluctuate under the influence of climate parameters (temperature and precipitation) [ 39 ].…”

Plant-derived essential oils (EOs) are used in medicines, disinfectants, and aromatherapy products. Information on the antifungal activity of EO of Alpinia zerumbet var. exelsa (known as Daito-gettou) found in Kitadaito Island, Okinawa, is limited. Therefore, we aimed to evaluate the antifungal activity of EOs obtained via steam distillation of leaves of Daito-gettou, which is a hybrid of A. zerumbet and A. uraiensis. Daito-gettou EO showed antifungal activity (minimum inhibitory concentration = 0.4%) against Aspergillus brasiliensis NBRC 9455, which was comparable to that of A. zerumbet found in the Okinawa main island. Gas chromatography/mass spectrometry revealed that the main components of Daito-gettou EOs are γ-terpinene, terpinen-4-ol, 1,8-cineole, 3-carene, and p-cymene. Terpinen-4-ol content (MIC = 0.075%) was 17.24%, suggesting that the antifungal activity of Daito-gettou EO was mainly attributable to this component. Daito-gettou EO and terpinen-4-ol inhibited mycelial growth. Moreover, calorimetric observations of fungal growth in the presence of Daito-gettou EO showed a characteristic pattern with no change in the initial growth rate and only a delay in growth. As this pattern is similar to that of amphotericin B, it implies that the action mode of Daito-gettou EO and terpinen-4-ol may be fungicidal. Further studies on the molecular mechanisms of action are needed for validation.
