Lemna Minor L. As a Source of Antioxidants

Abstract

Lemna Minor L. (LM) is a perennial aquatic plant that belongs to the genus Lemna, the family Lemnaceae and is spread almost ubiquitously. In folk medicine, it is used in the treatment of allergies, asthma, vitiligo, jaundice, glaucoma, rheumatism, gout, and others. In recent years it has become clear that its chemical composition consists of: proteins (up to 35%), vegetable fibers (up to 17%), fats (up to 5%), polysaccharides, flavonoids, amino acids, aliphatic acids, phenolic acids, triterpene compounds, vitamins, micro- and macro-elements and other substances. А significant part of these substances exhibit the antioxidant activity. The scientific information for 12 biologically active substances with antioxidant activity isolated from Lemna Minor is presented in the review.

Determination of chemical content of Lemna minor L. by GC-MS and investigation of antioxidant activity

“…Hexanal, also called hexanaldehyde or caproaldehyde, is used as a food additive due to its shelf life extension and flavoring properties. Tacheva et al, in their similar study, they stated that L. minor extract has 12 different antioxidant compounds (phytol, campesterol, loliolide, dihydroactinidiolide, ascorbic acid, vanillic acid, 2,3dihydroxybenzoic acid, caffeic acid, chlorogenic acid, esculetin, esculin and fraxetin) [23]. Their content analysis is similar to our study.…”

The Latest Application of Tubifex as Live Feed in Aquaculture

“…Agricultural waste is frequently wasted and dumped in landfills where it rots. According to several studies (Alam et al, 2021;Khaerunnisa et al, 2021;Mandal et al, 2016;Petrova-Tacheva, Ivanov, & Atanasov, 2020;Safrina et al, 2015;Umidayati et al, 2020), organic waste is rich in organic materials that can be useful after fermentation. Tubifex can be created using organic waste.…”

“…Lemna minor contains about 35%, 17%, and 5% protein, fiber, and fat respectively. Flavonoids, phenolics, vitamins, and other micromolecular components are among the active ingredients found in Lemna minor (Petrova-Tacheva et al, 2020). Lemna minor fermented in mud was used in an experiment by (Mahendra et al, 2019) as a food source substrate for worms.…”

Overview of Allelopathic Potential of Lemna minor L. Obtained from a Shallow Eutrophic Lake

“…According to the data contained in the literature, the cell wall of Lemna minor consists of: carbohydrates (51.2%), dry starch (19.9%), cellulose, and pectins (20.3%), along with galacturonan, xylogalacturonan, rhamnogalacturonan, and hemicellulose (3.5%), with xyloglucan and xylan and phenols (0.03%) [ 10 ]. The chemical composition indicates that in the dry matter of L. minor , there are: proteins (up to 35%), fibers (up to 17%), fats (up to 5%), polysaccharides, flavonoids, amino acids, aliphatic compounds, phenolic acids, triterpenes, micro- and macronutrients, vitamins (A, B, and E), and carotenoids [ 10 , 11 , 32 ]. Among fatty acids, the most numerous are polyunsaturated fatty acids (PUFA), which constitute 60-63% of all fatty acids [ 33 ].…”
