Abstract

This study explores an innovative and environmentally friendly method for extracting essential oils (EOs) from agarwood using custom natural deep eutectic solvents (DESs), and the optimal DES-solvent system was choline chloride and lactic acid. Compared with the traditional water distillation method, the extraction efficiency of essential oil of agarwood was increased 2.12 times by using the DESs system in this study. Gas chromatography-mass spectrometry (GC-MS) analysis revealed a richer profile of sesquiterpenes and alkane hydrocarbons in DES-extracted oils, and the results of the antioxidant activity experiments showed that the DES agarwood essential oil (IC₅₀ = 9.3602 mg/mL) had higher antioxidant activity than the essential oil extracted by traditional water distillation (IC₅₀ = 10.2261 mg/mL). Scanning electron microscopy (SEM) confirmed that DESs effectively disrupt agarwood cell walls, facilitating a more complete release of aromatic compounds while preserving volatile components. Additionally, DESs are biodegradable and exhibit reduced toxicity, offering a sustainable alternative in the essential oil extraction industry. This research underscores the potential of DES-based extraction techniques as a viable and superior method for producing high-quality agarwood EO, with significant implications for sustainable practices in the fragrance and pharmaceutical industries.

用定制的天然深共熔溶剂优化沉香精油的绿色提取：化学分析和生物活性评价

本研究探索了一种创新的、环保的沉香精油提取方法，采用定制的天然深度共晶溶剂（des）提取沉香精油，最佳的des溶剂体系为氯化胆碱和乳酸。与传统的水蒸馏法相比，采用DESs系统提取沉香精油的效率提高了2.12倍。气相色谱-质谱（GC-MS）分析表明，DES沉香精油中含有丰富的倍半萜和烷烃，抗氧化活性实验结果表明，DES沉香精油的抗氧化活性（IC50 = 9.3602 mg/mL）高于传统水蒸馏法提取的沉香精油（IC50 = 10.2261 mg/mL）。扫描电镜（SEM）证实，DESs有效地破坏沉香细胞壁，促进芳香化合物的更完全释放，同时保留挥发性成分。此外，DESs是可生物降解的，具有较低的毒性，为精油提取行业提供了可持续的替代品。这项研究强调了基于des的提取技术作为生产高质量沉香精油的一种可行和优越的方法的潜力，对香料和制药工业的可持续实践具有重要意义。
