Comparative study of Elyonurus muticus and Cymbopogon essential oils: potential as food preservative and surface coating of strawberries

Abstract

The chemical characterization of the three plants was accessed through the fundamental analysis, according to AOAC (2000), for moisture, ashes, protein, fibers and lipids (Soxlet -1879), all of them with five replicates (n=5). The carbohydrate content was obtained by difference (not counting the fibers already determined).The chemical composition (Table 1) of the plants evaluated, showed similar composition among the three studied grasses. The significant differences found were in the ashes and lipids content, indicating lower values for E. muticus and C. flexuosus species. Table 1. Chemical composition and essential oil yield of the plants C. flexuosus, C. citratus and E. muticus essential oils from hydrodistillation Constituent (%) Cymbopogon flexuosus Cymbopogon citratus Elyonurus muticus

Bioactive compounds extraction from different lemongrass species: Strategies and deep eutectic solvents evaluation

“…Thus, the extracts of the three lemongrasses presented the citral compound in different concentration, corroborating with an essential oil study of the three lemongrasses (Toazza et al, 2021).…”

“…Also, the citral compound present several employments in different industries as food, pharmaceutical, and perfumery. Thus, the extracts of the three lemongrasses presented the citral compound in different concentration, corroborating with an essential oil study of the three lemongrasses (Toazza et al, 2021). (0.061 c mg EDTA/ml ± 0.004), and E. muticus (0.075 b mg EDTA/ml ± 0.001).…”

“…The main bioactive compounds found by hydrodistillation in these lemongrass species are citral (Toazza et al, 2021), being a monoterpene, hydrophobic and characteristic lemon aroma (Ganjewala, Gupta, & Muhury, 2012) and myrcene, which is also a monoterpene, hydrophobic, with a characteristic geranium odor and present in the oily part of lemongrasses (Behr & Johnen, 2009). Therefore, these compounds present a hydrophobic character, and consequently, present a high affinity with the more nonpolar solvents.…”

“…Some significant results have already been obtained employing traditional methods of extraction of bioactive compounds from these lemongrasses' species, as antioxidant (Boeira et al, 2018; Hess et al, 2007; Roriz, Barros, Carvalho, Santos‐Buelga, & Ferreira, 2015), chelating (Toazza, Marques, Amaral, & Masson, 2021; Viuda‐Martos et al, 2010) and antimicrobial agents (Gao et al, 2020; Gupta, Muhury, & Ganjewala, 2016; Shi et al, 2016). Commonly, the methods so far used are steam distillation or hydrodistillation as extraction method, to obtain exclusively its essential oils.…”

“…Accordingly, it has been applied in the production of vitamin A as crude material (Wifek, Saeed, Rehman, & Nisar, 2016), flavoring in food and beverage industries (Shi et al, 2016) and as cosmetic and drug ingredient (Alam, Varshney, Khan, Laskar, & Younus, 2018;Idrees et al, 2015). Some significant results have already been obtained employing traditional methods of extraction of bioactive compounds from these lemongrasses' species, as antioxidant (Boeira et al, 2018;Hess et al, 2007;Roriz, Barros, Carvalho, Santos-Buelga, & Ferreira, 2015), chelating (Toazza, Marques, Amaral, & Masson, 2021;Viuda-Martos et al, 2010) and antimicrobial agents (Gao et al, 2020;Gupta, Muhury, & Ganjewala, 2016;Shi et al, 2016).
