“…Previous research has demonstrated that EOs exhibit strong antimicrobial effects when their MIC values are below 100 μg/mL. 51,52 According to this criterion, the EOs derived from the leaves and rhizomes of D. benenica in our study exhibited significant antimicrobial activity.…”

“…The potency of these EOs was quantitatively evaluated using minimum inhibitory concentration (MIC) and halfmaximal inhibitory concentration (IC 50 ) values, as presented in Table 5. The results indicated that the EOs from the leaves and rhizomes demonstrated activity against all 3 Gram-positive 51,52 According to this criterion, the EOs derived from the leaves and rhizomes of D. benenica in our study exhibited significant antimicrobial activity. The primary reason behind the antimicrobial properties of D. benenica EOs seems to be the presence of active components, particularly monoterpenes and their derivatives.…”

In recent years, essential oils (EOs) have gained popularity for their potential as natural antimicrobial agents and mosquito larvae control. This study aimed to explore the chemical composition of EOs extracted from the leaves and rhizomes of Distichochlamys benenica Q.B. Nguyen & Škorničk, and to evaluate their mosquito larvicidal and antimicrobial activities. The EOs were obtained using hydrodistillation and subjected to gas chromatography (GC) and GC-mass spectrometry to determine their chemical constituents. The main components identified in the leaf EO were β-pinene (47.7%), cis-β-elemene (8.5%), and α-pinene (7.8%), while the rhizome EO mainly consisted of geranyl acetate (25.7%), geranial (23.3%), neral (16.6%), and geraniol (8.4%). The mosquito larvicidal activity of the EOs was evaluated using larvae of Aedes aegypti and Culex quinquefasciatus during 24 and 48 h of treatment. The results demonstrated that these EOs effectively inhibited the mosquito larvae, with LC50 values ranging from 31.15 to 71.53 μg/mL and LC90 values ranging from 46.28 to 148.66 μg/mL. Additionally, the minimum inhibitory concentration (MIC) and half-maximal inhibitory concentration (IC50) values were used to evaluate the antimicrobial efficacy of EOs. Both EOs exhibited potent antimicrobial effects against Enterococcus faecalis ATCC 299212, Staphylococcus aureus ATCC 25923, Bacillus cereus ATCC 14579, Pseudomonas aeruginosa ATCC 27853, and Candida albicans ATCC 10231, with MIC values ranging from 16 to 64 μg/mL and IC50 values ranging from 4.67 to 45.67 μg/mL. Overall, the mosquito larvicidal and antimicrobial activities of D. benenica EOs highlight their potential as natural alternatives for combating mosquito-borne diseases and microbial infections.

“…On the other hand, Souza and co-workers established that compounds with MIC ≤ 1000 μg/mL display relevant antifungal activity, whereas MIC ≤ 250 μg/mL denotes highly interesting antifungal activity [65]. Based on these criteria, and inspired by the Oliveira and co-workers' review [66], in this study, the antifungal activity will be classified as follows: MIC ≤ 10 µg/mL, 10 < MIC ≤ 100 µg/mL, 100 < MIC ≤ 500 µg/mL, and 500 < MIC ≤ 1000 µg/mL denotes high, good, moderate, and weak activities, whereas MIC > 1000 µg/mL indicate inactivity.…”

This study reports on the chemical composition and antileishmanial and anticandidal activities of essential oils (EOs) distilled from Schinus molle dried leaves (SM-EO), Cinnamomum cassia branch bark (CC-EO) and their blends against promastigote forms of Leishmania (Leishmania) ama-zonensis and nine Candida strains. Major constituents of SM-EO were spathulenol (26.93%), β-caryophyllene (19.90%), and caryophyllene oxide (12.69%), whereas cinnamaldehyde (60.11%), cinnamyl acetate (20.90%) and (E)-cis-2-methoxycinnamic acid (10.37%) were predominant in CC-EO. SM-EO (IC50 = 21.45 µg/mL) and CC-EO (IC50 = 23.27 µg/mL) displayed good activity against L. amazonensis. SM-EO and CC-EO also proved to be good or moderate activity against nine Can-dida strains, with Minimum Inhibitory Concentration (MIC) values ranging from 31.25 to 250 µg/mL. While the three SM-EO and CC-EO blends were not more active than the EOs tested in-dividually, they exhibited remarkably high antileishmanial activity, with IC50 values ranging between 3.12 and 7.04 µg/mL, which is very similar to the IC50 of amphotericin B (positive con-trol). These results show that SM-EO, CC-EO, and their blends may be considered to participate in the formulation of drugs with antileishmanial and antifungal activities.

“…15 Along with treating mental and neurological illnesses, the plant is used as an insecticide in the treatment of sweating, fever, rheumatism, and rheumatoid arthritis. 16,17 Artemisia is rich in terpenoids, avonoids, coumarins, acetylenes, caffeoylquinic acids, and sterols. The plant has also been identied as having benecial activity as an antimalarial, antiviral, antitumor, antipyretic, antihemorrhagic, anticoagulant, antianginal, antioxidant, antihepatitis agent.…”
