Summary: Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) evaluated the safety and efficacy of laurel leaf oil as an additive for all animal species. The use of the additive at different levels was found to have varying levels of concern for different animal species, with lower levels considered safe for dogs and cats. However, the additive was also found to have potential irritant effects on the skin, eyes, and respiratory tract, and due to the high concentration of methyleugenol, it was classified as suspected of causing genetic defects and cancer.

Summary: Alkenylbenzenes are natural secondary plant metabolites, some of which are proven genotoxic carcinogens. This review provides an overview of the occurrence of potentially toxic alkenylbenzenes in essential oils and extracts used for flavoring purposes in food. It focuses on well-known genotoxic alkenylbenzenes like safrole, methyleugenol, and estragole, but also considers other alkenylbenzenes commonly used for flavoring. The review emphasizes the need for quantitative occurrence data on alkenylbenzenes in plants and final plant food supplements, processed foods, and flavored beverages for more reliable exposure assessment in the future.

Summary: Pulses are an important source of nutrition, but their safe storage is challenging due to spoilage by pests before and after harvest. This study evaluated the potential of Indian sweet basil essential oil and its constituent estragole as insecticides against the pulse beetle. The results showed that both the essential oil and estragole had strong fumigant and contact toxicity against the beetle, causing 100% mortality within 24 hours.

Summary: This study aimed to determine the optimal harvest period for high essential oil and estragole yield in perennial fennel plants grown under culture conditions. Four different harvest periods were carried out, including vegetative development, pre-flowering stage, and full flowering stage. The results showed that the highest estragole yield was obtained from the pre-flowering period. The essential oil yield varied depending on the developmental stages of the plants, with the period before flowering being the most suitable.

Summary: A comprehensive study was conducted to characterize the chemical composition of essential oils from Matricaria aurea, a plant species grown in Saudi Arabia and Jordan. The results showed that the essential oils from Saudi M. aurea were mainly composed of oxygenated sesquiterpenes, while the essential oils from Jordanian M. aurea were dominated by sesquiterpene hydrocarbons. These findings revealed interesting differences in the chemical compositions of M. aurea essential oils from different regions.

Summary: This study investigated the effects of phosphate and potassium fertilization on the growth characteristics and oil quality of Crambe plants. The results showed that both potassium and phosphorus fertilization significantly increased the vegetative growth traits and fixed oil content. However, they had opposite effects on the main components of Crambe oil, with potassium fertilization increasing erucic acid content and phosphorus fertilization decreasing it.

Summary: This study aimed to investigate the impact of four invasive plant species on soil dynamics. The results showed that although these invasive plants had some effects on soil properties, ions, and microelements, most of the parameters did not show significant changes. This suggests that the impact of invasive plants on soil dynamics varies depending on the invasive species and the invaded habitat.

Summary: The growth and quality of medicinal plants are significantly affected by environmental stress, particularly water shortages. This research investigated the impact of varying irrigation intervals and partial replacement of mineral fertilizers with biofertilizer on the growth, yield, and essential oil content of lemongrass. The study found that drought and reduced NPK levels led to decreased growth characteristics and leaf greenness, but increased proline content and essential oil percentage. It is recommended to reduce mineral fertilizer to 50-75% NPK combined with biofertilizer and space irrigation intervals every 10-15 days to achieve high essential oil yield and maintain productivity under environmental constraints.
