Rosemary, oregano, pink savory, lemon balm, St. John's wort, and saffron are common herbs wildly grown and easily cultivated in many countries. All of them are rich in antioxidant compounds that exhibit several biological and health activities. They are commercialized as spices, traditional medicines, or raw materials for the production of essential oils. The whole herbs or the residues of their current use are potential sources for the recovery of natural antioxidant extracts. Finding effective and feasible extraction and purification methods is a major challenge for the industrial production of natural antioxidant extracts. In this respect, the present paper is an extensive literature review of the solvents and extraction methods that have been tested on these herbs. Green solvents and novel extraction methods that can be easily scaled up for industrial application are critically discussed.
迷迭香、牛至、香薄荷、柠檬香脂、贯叶连翘和藏红花是常见的草本植物，在许多国家广泛种植且易于栽培。它们都富含抗氧化化合物，具有多种生物和保健活性。它们被商业化用作香料、传统药物或生产精油的原料。整株植物或其当前用途的残留物是回收天然抗氧化提取物的潜在来源。找到有效且可行的提取和纯化方法是天然抗氧化提取物工业化生产的主要挑战。在这方面，本文对已在这些草药上测试过的溶剂和提取方法进行了广泛的文献综述。本文还批判性地讨论了可用于工业应用的绿色溶剂和新型提取方法。
