Abstract

Essential oils are concentrated liquids of intricate combinations of volatile substances, extracted from various plant parts. Several bioactive substances with antibacterial and antioxidant activities are abundant in essential oils. Some essential oils have also been employed in medicine. Due to the risk associated with employing synthetic preservatives, the use of essential oils as natural additives for extending the shelf life of food products has also drawn considerable attention. They are used in the pharmaceutical, cosmetic, and food industries for their functional properties. There are various methods for extraction, but both the quality and the percentage yield of essential oil never remain the same. So, innovative and non-conventional techniques of essential oils extraction from medicinal plants were evoled to get quantitative and qualitative yield. In the present article, we searched and reviewed innovative techniques used for the extraction of essential oils from medicinal and aromatic plants through electronic searches of PubMed, Medline, Wiley, Scopus, and Google Scholar. For the extraction of essential oils, several innovative/non-conventional techniques have been reported in literature. Extraction of essential oil by using innovative techniques retards the risk of losing the essential components of plants, maintains the quality, reduces chemical risk, extraction time, acts eco-friendly, and increases the percentage yield of the essential oils. This paper presents the success story of innovative extraction methods of essential oils in accordance with sustainable development and environmental protection.
从药用植物中提取精油的创新方法
精油是从各种植物部位提取的挥发性物质的复杂组合的浓缩液体。精油中含有多种具有抗菌和抗氧化活性的生物活性物质。一些精油也被用于医学。由于与使用合成防腐剂相关的风险,使用精油作为延长食品保质期的天然添加剂也引起了相当大的关注。由于其功能特性,它们被用于制药、化妆品和食品工业。有各种各样的提取方法,但精油的质量和提取率永远不会保持不变。因此,不断发展创新和非常规的药用植物精油提取技术,以获得定量和定性的产量。在这篇文章中,我们通过PubMed, Medline, Wiley, Scopus和谷歌Scholar的电子检索,检索和回顾了用于药用和芳香植物精油提取的创新技术。对于精油的提取,文献中报道了几种创新/非传统的技术。采用创新技术提取精油,降低了植物基本成分流失的风险,保持了质量,减少了化学风险,缩短了提取时间,对环境友好,提高了精油的产量百分比。本文介绍了符合可持续发展和环境保护的创新精油提取方法的成功案例。
