Efficient pretreatment is essential for unlocking the biorefining potential of lignocellulosic biomass. In this study, a mild and synergistic pretreatment strategy was established using ethylenediamine (EDA) and sodium carbonate (Na₂CO₃) at 85°C under atmospheric pressure. Following optimization, the process enabled effective fractionation of corn stover, removing 85.17 % of lignin while retaining 66.52 % of cellulose, and subsequently achieving a 92.57 % enzymatic glucose yield (0.68 g/g substrate). Mechanistic analyses integrating FTIR, semi-quantitative GC-MS, and DFT calculations revealed that the synergistic interplay between EDA and Na₂CO₃ promotes cleavage of dominant lignin interunit linkages. EDA forms stabilizing hydrogen bonds and facilitates nucleophilic substitution at the Cα position, whereas the alkaline environment generated by Na₂CO₃ favors oxygen-anion formation at the Cβ site, collectively driving lignin depolymerization. As a result, lignin is selectively converted into soluble products, including identifiable aromatic monomers. The pretreatment system also exhibited strong recyclability, maintaining 63.60 % lignin removal and 75.44 % glucose conversion after six reuse cycles. Overall, the EDA-Na₂CO₃ strategy enables high sugar yields under mild, low-energy conditions, offering a promising and sustainable pathway for integrated lignocellulosic biorefining.

Zanthoxylum oil, which is prepared by diluting CO₂ supercritical extracts with soybean oil, contains volatile oils and amide compounds. During storage, light, acidity, and temperature are the main factors causing the decrease in pungent components. The temperature-induced degradation mechanisms of these compounds remain ambiguous, which is challenging, because thermal effects significantly decrease product quality and sensory acceptability. In this study, the effect of temperature on pungent amides in Zanthoxylum oil was investigated, with a focus on characteristic spectra, degradation kinetics, and mechanistic analysis, to elucidate thermal degradation patterns and molecular mechanisms. The results indicate that hydroxy-α-sanshool, the principal amide, undergoes notable thermal degradation, with its degradation increasing proportionally with temperature. High-temperature treatments induce the isomerization of hydroxy-α-sanshool into hydroxy-β-sanshool and hydroxy-ε-sanshool, as well as oxidative transformation into compounds such as (2E,6Z,10E)-8,9-dihydroxy-N-(2-hydroxy-2-methylpropyl)dodeca-2,6,10-trienamide and (2E,6Z,8E)-10,11-dihydroxy-N-(2-hydroxy-2-methylpropyl)dodeca-2,6,8-trienamide. These findings provide a scientific basis for optimizing processing strategies to mitigate degradation and increase the shelf life of Zanthoxylum-derived products.
花椒油是用大豆油稀释CO₂超临界萃取物制成的，含有挥发油和酰胺类化合物。在贮藏过程中，光、酸度和温度是导致刺鼻成分减少的主要因素。这些化合物的温度诱导降解机制仍然不明确，这是具有挑战性的，因为热效应显著降低产品质量和感官可接受性。本文研究了温度对花椒油中刺激性酰胺的影响，重点从特征光谱、降解动力学和机理分析等方面进行了研究，以阐明热降解模式和分子机制。结果表明，主要酰胺羟基-α-三酚发生了明显的热降解，降解程度随温度的升高成比例增加。高温处理诱导羟基-α-三酚异构化为羟基-β-三酚和羟基-ε-三酚，并氧化转化为(2E,6Z,10E)-8,9-二羟基- n -（2-羟基-2-甲基丙基）十二-2,6,10-三烯酰胺和(2E,6Z,8E)-10,11-二羟基- n -（2-羟基-2-甲基丙基）十二-2,6,8-三烯酰胺等化合物。这些发现为优化花椒衍生产品的加工策略以减轻降解和延长保质期提供了科学依据。

Plant essential oils are widely recognized for their insecticidal and repellent properties; however, their practical application in pest management is often constrained by poor stability and rapid volatilization. To address this limitation, we developed a sustained-release delivery system for Artemisia lavandulaefolia essential oil based on electrospinning technology. Chemical analysis identified 47 constituents in the essential oil, with 1,8-cineole as the dominant component (45.2 %). Three fabrication strategies—uniaxial electrospinning, uniaxial particle formation, and coaxial electrospinning—were systematically compared with respect to their sustained-release performance. Among them, coaxial electrospinning exhibited the most favorable release behavior, achieving a prolonged release period exceeding 42 days and showing excellent agreement with a first-order kinetic model (R² = 0.99). Bioassays demonstrated that the coaxial electrospun fiber membrane significantly disrupted key life-history traits of the target insect species, including a 26.9 % extension of larval development, a 52.8 % reduction in adult lifespan, a 50.0 % decrease in oviposition, and a 19.7 % reduction in fourth-instar body weight compared with the control. These results indicate pronounced adverse effects on insect growth and reproductive performance. Overall, this study presents an eco-friendly strategy for enhancing the persistence and biological efficacy of plant-derived insecticides. By integrating essential oils into a controlled-release electrospun fiber matrix, this work offers a promising platform for the development of more sustainable pest management technologies in agriculture.
