Lemongrass contains a variety of substances that are known to have antioxidant and disease-preventing properties, including essential oils, compounds, minerals, and vitamins. Lemongrass () essential oil (LGEO) has been demonstrated to ameliorate diabetes and accelerate wound healing. A member of the Poaceae family, Lemongrass, a fragrant plant, is cultivated for the extraction of essential oils including myrcene and a mixture of geranial and neral isomers of citral monoterpenes. Active constituents in lemongrass essential oil are myrcene, followed by limonene and citral along with geraniol, citronellol, geranyl acetate, neral, and nerol, which are beneficial to human health. A large part of lemongrass' expansion is driven by the plant's huge industrial potential in the food, cosmetics, and medicinal sectors. A great deal of experimental and modeling study was conducted on the extraction of essential oils. Using Google Scholar and PubMed databases, a systematic review of the literature covering the period from 1996 to 2022 was conducted, in accordance with the PRISMA declaration. There were articles on chemistry, biosynthesis, extraction techniques and worldwide demand of lemongrass oil. We compared the effectiveness of several methods of extracting lemongrass essential oil, including solvent extraction, supercritical CO2 extraction, steam distillation, hydrodistillation (HD), and microwave aided hydrodistillation (MAHD). Moreover, essential oils found in lemongrass and its bioactivities have a significant impact on human health. This manuscript demonstrates the different extraction techniques of lemongrass essential oil and its physiological benefits on diabetic wound healing, tissue repair and regeneration, as well as its immense contribution in ameliorating arthritis and joint pain.Key teaching pointsThe international market demand prediction and the pharmacological benefits of the Lemongrass essential oil have been thoroughly reported here.This article points out that different extraction techniques yield different percentages of citral and other secondary metabolites from lemon grass, for example, microwave assisted hydrodistillation and supercritical carbon dioxide extraction process yields more citral.This article highlights the concept and application of lemongrass oil in aromatherapy, joint-pain, and arthritis.Moreover, this manuscript includes a discussion about the effect of lemongrass oil on diabetic wound healing and tissue regeneration - that paves the way for further research.
柠檬草含有多种具有抗氧化和预防疾病特性的物质，包括精油、化合物、矿物质和维生素。柠檬草精油 (LGEO) 已被证明可改善糖尿病并加速伤口愈合。柠檬草是禾本科的一种芳香植物，因其可提取精油而被种植，包括月桂烯和柠檬醛的混合物，柠檬醛是单萜类化合物的橙花醛和香叶醛异构体。柠檬草精油中的活性成分是月桂烯，其次是柠檬烯和柠檬醛，以及香茅醇、香茅醇、乙酸香叶酯、橙花醛和橙花醇，这些成分对人体健康有益。柠檬草的大量扩张是由其在食品、化妆品和医药领域的巨大工业潜力驱动的。人们对精油的提取进行了大量的实验和模型研究。根据 PRISMA 声明，使用 Google Scholar 和 PubMed 数据库，对 1996 年至 2022 年期间的文献进行了系统综述。这些文章涵盖了柠檬草油的化学、生物合成、提取技术和全球需求。我们比较了几种柠檬草精油提取方法的效果，包括溶剂提取、超临界 CO2 提取、水蒸气蒸馏、水蒸馏 (HD) 和微波辅助水蒸馏 (MAHD)。此外，柠檬草中的精油及其生物活性对人类健康有重大影响。本文展示了柠檬草精油的不同提取技术及其对糖尿病伤口愈合、组织修复和再生的生理益处，以及其在改善关节炎和关节疼痛方面的巨大贡献。
本文全面报道了柠檬草精油的国际市场需求预测和药理学益处。
本文指出，不同的提取技术从柠檬草中提取出不同比例的柠檬醛和其他次生代谢物，例如微波辅助水蒸馏和超临界二氧化碳提取工艺可产生更多的柠檬醛。
本文重点介绍了柠檬草油在芳香疗法、关节疼痛和关节炎中的概念和应用。
此外，本文还讨论了柠檬草油对糖尿病伤口愈合和组织再生的影响，为进一步研究铺平了道路。
