“…Despite being the oldest method, hydrodistillation is still used today for extracting oils from different matrices. Essential oils from Rosmarinus officinalis L. [35], Ziziphora clinopodioides L. [36], Citrus latifolia Tanaka [37], and Zingiber officinale [38] are some of the medicinal plants where EOs can be extracted by hydrodistillation.…”

Essential oils (EOs) are complex mixtures of volatile compounds extracted from different parts of plants by different methods. There is a large diversity of these natural substances with varying properties that lead to their common use in several areas. The agrochemical, pharmaceutical, medical, food, and textile industry, as well as cosmetic and hygiene applications are some of the areas where EOs are widely included. To overcome the limitation of EOs being highly volatile and reactive, microencapsulation has become one of the preferred methods to retain and control these compounds. This review explores the techniques for extracting essential oils from aromatic plant matter. Microencapsulation strategies and the available technologies are also reviewed, along with an in-depth overview of the current research and application of microencapsulated EOs.

Background Ethiopians use Artemisia abyssinica and Lepidium sativum as immunity enhancers. However, there is no scientific validation conducted so far regarding this claim. The aim of this study was to investigate the in-vivo immunomodulatory activities of essential oils of A. abyssinica and L. sativum in mice. Methods The extraction was carried out using the earlier techniques. By hydro distilling fresh seeds and aerial portions of A. abyssinica and L. sativum , respectively, essential oils were obtained. Essential oils of both plants were tested at 100, 200 and 400 mg/kg. The rate of carbon clearance, humoral antibody titer, delayed type hypersensitivity response, spleen and thymus indices were evaluated in mice according to scientific protocols. The carbon clearance assay was determined using carbon ink. Sheep red blood cell was used as an antigen for other tests. Results Essential oils of A. abyssinica and L. sativum at 400 mg/kg significantly increased the rate of carbon clearance from the body of mice ( p <0.05). The maximum carbon clearance rate was achieved for A. byssinica essential oil at 400 mg/kg. Both essential oils raised the level of HAT to SRBC in comparison to the vehicle and cyclophosphamide administered groups. The largest (84.668±1.951) mean secondary HAT to SRBC was generated by L. sativum essential oil at 400 mg/kg ( p <0.001). A. abyssinica essential oil at 200 and 400 mg/kg significantly increased the level of thymus index compared to the model group ( p <0.05 and 0.01 respectively). The levamisole group experienced the highest increase in thymus index ( p <0.001). Essential oil of L. sativum at 400 mg/kg also increased the level of thymus index. The spleen index in mice was improved by the essential oils only at the highest dose levels (400 mg/kg). Conclusion It can be inferred that the essential oils of L. sativum and A. abyssinica have immunostimulant properties.
