摘要

茴芹(Renealmia)是一种热带植物,属姜科(Zingiberaceae)。在南美洲热带地区,茴芹植物以治疗骨痛、肌肉痛、感冒和蛇咬伤症状而闻名。尽管茴芹代谢物具有重要的生物医学价值,但对其精油(EO)成分的研究却很少,其中一个原因是当地缺乏高效、廉价和环保的精油提取方法。这项研究以微波辅助水蒸馏(MAHD)为基础,结合超声辅助萃取(UAE)预处理,优化了从鳞叶莲(Renealmia ligulata)植物的气生部分和根茎中提取菁华油的方法。采用响应面分析法研究了三种微波辅助水蒸馏萃取变量(辐射功率、辐射照射长度和溶剂体积)的单独和组合,以确定可获得最佳环氧乙烷产量的值组合。结果表明,最佳平均萃取持续时间为 42.5 分钟,对于 30 克植物气生部分材料,辐照功率为 765 瓦,溶剂体积为 225.9 毫升;对于 20 克植物根茎,辐照功率为 799 瓦,溶剂体积为 145 毫升。对获得的 R. ligulata EO 进行 GC-MS 分析后发现,其主要成分是表桉叶油醇(在植物气生部分中占 28%,在根茎中占 13%)。

Optimization of a novel Renealmia ligulata (Zingiberaceae) essential oil extraction method through microwave-assisted hydrodistillation
Renealmia is a tropical plant genus within the Zingiberaceae family. In tropical South America, Renealmia plants are known for their therapeutic uses against bone and muscle pain, colds, and to counteract snake bite symptoms. Despite the biomedical importance of Renealmia metabolites, the components of their essential oils (EO) have been scarcely studied, and a cause thereof is the lack of local efficient, inexpensive, and environmentally friendly EO extraction methods. This work addressed the optimization of an EO extraction method from the aerial parts and rhizomes of Renealmia ligulata plants based on microwave-assisted hydrodistillation (MAHD) with an ultrasound-assisted extraction (UAE) pretreatment. Three MAHD extraction variables (radiation power, radiation exposure length, and solvent volume) were studied on their own and in combination using a response surface analysis to determine the value combinations leading to optimal EO yields. The results showed that the best average extraction duration time was 42.5 min, combined with a radiation power of 765 W and a solvent volume 225.9 mL for 30 g of aerial part plant material or 799 W and 145 mL of solvent for 20 g of plant rhizomes. A GC-MS analysis of the obtained R. ligulata EOs revealed that their main component was epi-Eudesmol (28% in plant aerial parts and 13% in rhizomes), which is a molecule of interest considering its reported neuro-protective properties.
