Wood essential oil and wood products with special fragrances are high value-added forest products. Despite the availability of essential oil and volatile organic compounds (VOCs) from wood, their variation and dependence on tree age have not been examined. After essential oil extraction and wood processing, the yields and compositions of essential oils and VOCs in wood from trees of different ages (10a, 30a, and 80a) were determined. The yield of essential oil from 30a wood was significantly greater than that from 10a and 80a wood. Liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) revealed 672 and 41 volatile compounds, respectively, in the essential oil and wood, the majority of which exhibited large fluctuations in relative content and composition depending on tree age. Sesquiterpenoids, fatty acids and conjugates may greatly contribute to the main components of essential oil from wood. Almost all major sesquiterpenoid compounds, such as caryophyllene α-oxide, eudesmo, and cubebene, were identified in the essential oils from the 30a and 80a wood, and their relative contents were much greater than those in the 10a wood. The main components of the wood fragrance were sesquiterpenoids. The types and relative contents of sesquiterpenoids from wood increased with tree age. These results suggest that choosing wood from trees of a suitable age will significantly improve the efficiency of wood utilization.

CRISPR ribonucleoprotein (RNP)-mediated genome editing offers a transgene-free platform for precise genetic modification in diverse herbaceous and tree species, including rice, wheat, apple, poplar, oil palm, rubber tree and grapevine. However, its application in woody plants faces distinct challenges, notably inefficient delivery and regeneration difficulties, particularly in species such as bamboo. While some of these issues also occur in herbaceous plants, they are often significantly more complex in woody species due to factors such as intricate cell wall architecture, widespread recalcitrant genotypes and inherent limitations of current delivery platforms.

Nuclear factor erythroid 2-related factor 2 (Nrf2) is an essential component in regulating oxidative stress. Sulforaphane (SFN) is a natural antioxidant and gene agonist that can increase the antioxidant capacity of the organism and reduce oxidative stress. However, research on the repair of oxidative stress damage by SFN in aquatic animals remains extremely scarce.

Purpose: The rapid onset of anxiolytic drugs without cognitive or motor impairments remains an unmet need. This study evaluated the acute anxiolytic effects of Salvia heldreichiana essential oil in rats, measuring anxiety-related behaviors, hippocampal levels of serotonin, noradrenaline, gamma-aminobutyric acid GABA, and serum cortisol.
Method: Forty-eight male Wistar albino rats were divided into two experiments.

Huajiao seeds represent an underutilized high-quality woody oilseed resource rich in unsaturated fatty acids and diverse nutritional factors. This study investigated the quality characteristics and digestive behavior of two Huajiao seed oils (Zanthoxylum bungeanum seed oil (ZBSO) and Zanthoxylum schinifolium seed oil (ZSSO)). The results demonstrated that both oils were rich in unsaturated fatty acids, with ZBSO containing 76.

Lutein and omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), offer significant health benefits, especially when consumed together. However, their incorporation in food is often low due to their instability during processing and storage. Meat products play an essential role in human nutrition and are generally deficient in lutein and omega-3 fatty acids.
