The present work studied the effect of aqueous extract from duckweed Lemna minor frond on morphological state of the thyroid gland in the experimental hypothyroidism. Healthy albino rats weighing between 120 g and 150 g were used. The animalswere randomly allotted into four groups, each containing ten rats respectively. Three of the groups (II, III and IV) induced with hypothyroidism by 1 % solution of sodium perchlorate with drinking water for 20 days. Control (vehicle) rats were given normal saline. After 20 days hypothyroid groups (III and IV) of rats treated with aqueous extract from duckweed Lemna minor frond at a dose 0.5 ml/100 g of body weight and with Iodomarin 200 (reference drug) at a dose 12 µg/kg daily orally for 21 days. Results obtained from the study showed that the introduction of sodium perchlorate leads to morphological and functional changes in the structure of the thyroid gland in rats, accompanied by sings of hyperplastic tissue proliferation and corresponds with hypofunctional state. It was established that introduction of aqueous extract from duckweed Lemna minor frond has a positive effect on the restructuring of the thyroid gland in rats with hypothyroidism, increasing its functional activity. There is a decrease of proliferative processes by extrafolliсular epithelium and thyrocytes in the follicles. The outer diameter of follicles decreased by 7.65 % (P>0.05), the height and size of thyrocytes in the wall of the follicle were significantly decreased by 58.16 % and 18 41 %, respectively, compared to untreated hypothyroid group. The obtained results have practical significance for the development of drugs with thyroid-stimulating action for preventing or delaying the development of hypothyroidism and its complications.

“…In this regard, have been reported in Lemna species the presence of phenolic compounds, such as gallic acid, tannins, flavonoids, anthocyanins, quercetin, and other compounds like thiol and terpene as steroids. Which are known to have antimicrobial properties ( Effiong and Sanni, 2009 , Gülçin et al, 2010 , Leão et al, 2014 , Vladimirova and Georgiyants, 2013 , Al-snafi, 2019 , Mahizan et al, 2019 ). In hexane extract, terpene compounds as steroids should have the principal antimicrobial activity.…”

The treatment of bacterial diseases in aquaculture is done using antibiotics, their applications has resulted in contamination and bacterial resistance. Natural extracts are a potential alternative as an antimicrobial, they have demonstrated effectiveness in their use aimed at treating conditions. The purpose of this study was to evaluate the antimicrobial activity of Lemna minor extracts against Pseudomonas fluorescens with different solvent for extraction. Methanol, chloroform and hexane were used. Subsequently, the safety assessment of the extracts in Danio rerio embryos and larvae was performed to validate as ecologically harmless. Antibacterial activity was detected in three extracts with significant differences (p = 0.001). Hexane extract had the highest antibacterial activity, followed by chloroform and methanol extracts. The three extracts have differences with respect to the control, between times and concentrations tested (p = 0.001). Minimum inhibitory concentration values (MIC) at 24 h methanolic extract ME 0.05 µg mL −1 . In embryos and larvae increased safety of the LC 50 methanolic extract was evidenced followed by the hexane and chloroform extract. No morphological or tissue changes were observed in embryos and larvae. The hexane extracts of L. minor had a greater bactericidal effect against P. fluorescens and are functional because of their antibacterial activity, but methanolic extract is more safety in embryos and larvae of D. rerio , making it a potential alternative for use in the treatment and control of septicemia in fish.

“…L. minor contains a total saponin content 3.2 g/kg dried weight [ 28 ]. Phytosterols, such as Δ5-avenasterol, campesterol, cycloartenol, β,δ-sitosterol, and stigmasterol, have been reported in duckweeds [ 9 , 17 , 124 , 133 , 134 ]. Phytosterols account for approximately 20% of the wax fraction of S. polyrrhiza [ 134 ].…”

Duckweeds: their utilization, metabolites and cultivation

Duckweeds are floating plants of the family Lemnaceae, comprising 5 genera and 36 species. They typically live in ponds or lakes and are found worldwide, except the polar regions. There are two duckweed subfamilies—namely Lemnoidea and Wolffioideae, with 15 and 21 species, respectively. Additionally, they have characteristic reproduction methods. Several metabolites have also been reported in various duckweeds. Duckweeds have a wide range of adaptive capabilities and are particularly suitable for experiments requiring high productivity because of their speedy growth and reproduction rates. Duckweeds have been studied for their use as food/feed resources and pharmaceuticals, as well as for phytoremediation and industrial applications. Because there are numerous duckweed species, culture conditions should be optimized for industrial applications. Here, we review and summarize studies on duckweed species and their utilization, metabolites, and cultivation methods to support the extended application of duckweeds in future.
