Decontamination of poultry surfaces through appropriate hygiene and sanitation measures can partially mitigate bacterial problems, as this process does not result in the complete elimination of bacteria. Thus, the remaining bacteria can persist and contaminate eggshells. Therefore, regardless of the rigor of the sanitary standards applied on farms, it is suggested that hatching eggs be subjected to the sanitization process. Here, we investigated the effectiveness of essential oil-based antibacterial agents in sanitizing eggs. The results indicated that essential oils from (L.) J. Presl. (CCEO), (L.) Merr. & L.M. Perry (SAEO) and (L.) Rendle (CNEO), at specific concentrations, have antibacterial effects in vitro, reducing the load of mesophilic bacteria and enterobacteria in the eggshell by at least 3 and 2 log CFU/mL, respectively. The adoption of CCEO, SAEO and CNEO to reduce the bacterial load on eggshells could be a favorable change to the conventional protocol of egg sanitization with formaldehyde, especially on farms where sanitary standards are insufficient.

Geraniol is an acyclic monoterpene alcohol that is extracted from the essential oils of aromatic plants. Geraniol has several biological activities such as anti-cancer, anti-inflammatory, antioxidant, and neuroprotective effects. However, the pharmacokinetics of geraniol and its metabolites after oral administration remain unknown in mice.

A study was conducted to assess growth performance, methane (CH) emissions, and feeding behavior of feedlot steers consuming backgrounding and finishing diets with an essential oil blend (EO), monensin (Mon), and their combination (EO + Mon). The study was structured as a 2 × 2 factorial, with two feed additive treatments (Control, EO) and two monensin treatments (no Monensin, Monensin). One hundred Angus × steers were evenly distributed across each treatment into four pens, and each dietary phase consisted of four, 28-d periods.

Palm leaf manuscripts, crafted from specially treated palm leaves, are invaluable historical documents. However, they degrade and tend to become brittle over time. To date, plant essential oils and glycerin are the used materials to improve the flexibility of palm leaf manuscripts, but the effective duration of these materials is short due to their volatility.

Article Synopsis
- The study analyzes essential oil extracted from dry Eucalyptus globulus leaves, focusing on its chemical composition and potential health benefits.
- The oil consists of 20 identified compounds, primarily linalool, and exhibits antifungal properties against Fusarium roseum and antibacterial effects against Pseudomonas savastanoi.
- While it shows moderate antioxidant activity, it differs from typical eucalyptus oils by being a linalool chemotype rather than eucalyptol-dominant.

This study evaluated the antioxidant and antiproliferative effects of aqueous, ethanolic and methanolic extracts of Sedum nicaeense flowers and leaves. The MTT assay assessed cytotoxicity against colorectal cancer cells (Caco-2, HCT-116), breast cancer cells (T47D, MCF-7) and normal fibroblasts (MRC-5), while the ferric-reducing antioxidant power (FRAP) assay measured antioxidant capacity. Essential oils from flowers and leaves were analyzed using gas chromatography-mass spectrometry (GC-MS).
