“…The vitexin and apigenin in duckweed have been suggested as constituents for treating non-small lung cancer [55] and as anticancer adjuvants, and flavone C-glycosides from L. japonica exhibits cytotoxic activity against various human cancer cell lines (HepG-2, SW-620, A-549) [87]. In particular, L. minor flavonoids have immunosuppressive effects by reducing free hemoglobin content and antibody production in human whole blood [87]. Moreover, fruit and vegetable consumption rich in polyphenolic substances and iron chelating agents prevent cancer by ROS scavenging [85].…”

Bleomycin (BLM) administration is associated with multifunctional proteins inflammations and induction of idiopathic pulmonary fibrosis (IPF). Lemna minor L. extract, a free-floating monocot macrophyte possesses antioxidant and anti-inflammatory potential. The aim of the study was to examine the protective effect of L. minor extract on lung protein oxidation and oxidative stress modulation by BLM-induced pulmonary fibrosis in Balb/c mice. For this purpose, the protein carbonyl content, advanced glycation end product, nitroxide protein oxidation (5-MSL), and lipid peroxidation (as MDA and ROS), in lung cells were examined. The histological examinations, collagen deposition, and quantitative measurements of IL-1β, IL-6, and TNF in lung tissues and blood were investigated. Intraperitoneal, BLM administration (0.069 U/mL; 0.29 U/kg b.w.) for 33 days, caused IPF induction in Balb/c mice. Pulmonary combining therapy was administered with L. minor at dose 120 mg/mL (0.187 mg/kg b.w.). L. minor histologically ameliorated BLM induced IPF in lung tissues. L. minor significantly modulated (p < 0.05) BLM-alterations induced in lung hydroxyproline, carbonylated proteins, 5-MSL-protein oxidation. Oxidative stress decreased levels in antioxidant enzymatic and non-enzymatic systems in the lung were significantly regulated (p < 0.05) by L. minor. L. minor decreased the IL-1β, IL-6, and TNF-α expression in lung tissues and plasma. The L. minor improves the preventive effect/defense response in specific pulmonary protein oxidation, lipid peroxidation, ROS identifications, and cytokine modulation by BLM-induced chronic inflammations, and could be a good antioxidant, anti-inflammatory, and anti-fibrotic alternative or IPF prevention involved in their pathogenesis.

“…All nine essential amino acids are also found in this plant [11]. Previous studies have revealed the presence of 20-35% protein, 4-7% fat, and 4-10% starch in plants from Lemnaceae, and W. globosa has been used as a protein source in animal feed and as a raw material for many industrial products including bioalcohol and biodegradable plastics [12,13].…”

Wolffia globosa, or watermeal, is an aquatic plant belonging to the Lemnaceae family that is consumed as food and sold in local markets of Thailand. The aim of this study was to quantify selected active compounds and minerals in W. globosa ethanolic extract and evaluate its antioxidant activity. Total phenolic, flavonoid, and anthocyanin contents were analyzed. High-performance liquid chromatography was used for the determination of beta-carotene, ferulic acid, luteolin-7-O-β-D-glucoside, and kaempferol. Mineral contents (iron, potassium, calcium, magnesium, zinc, and sodium) were determined by atomic absorption spectroscopy. Antioxidative activity was evaluated by DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azobis (3-ethylbenzothiazoline-6-sulfonic acid)) radical scavenging assays. The beta-carotene, ferulic acid, luteolin-7-O-β-D-glucoside, and kaempferol contents of the extract were 2.52 ± 0.10, 1.40 ± 0.10, 2.42 ± 0.50, and 1.57 ± 0.14 mg/g extract, respectively. The highest mineral content in the W. globosa extract was magnesium. The wet extract of W. globosa showed higher amounts of all minerals than the dry extract. Freshly prepared and boiled W. globosa extracts showed radical scavenging activity at 1000 µg/milliliter with 75.77 ± 0.93% and 67.10 ± 0.20% inhibition of DPPH and 70.40 ± 7.20% and 59.78 ± 3.16% inhibition of ABTS, respectively. This plant is a promising novel source of natural phytochemical constituents and antioxidants and has potential for development as a plant-based nutraceutical product for the treatment of diseases caused by free radicals.

“… 25 Duckweeds contain a variety of secondary metabolites, including phenolic compounds (favonoids, phenylpropanoids, and tannins) and terpenoids. 26 L. punctata is known to have a higher favonoid content, such as apigenin, luteolin, vitexin, orientin and its derivatives, which have a variety of bioativities. 27 , 28 Among them, the compound luteolin has been identified to inhibit the growth of M. aeruginosa remarkably with IC 50 6.5 mg/L.…”

To study the allelopathic effect of the extracts of Landoltia punctata , the changes of cell density of Microcystis aeruginosa were measured. The anti-algae allelopathic effect of different organic solvent extracts of L. punctata was evaluated, and the physiological, biochemical indexes were determined to discuss the mechanism of algal inhibition. The results showed that the petroleum ether, dichloromethane and ethyl acetate extracts showed various inhibitory effects on M. aeruginosa . Among them, ethyl acetate extract was the most strongly allelopathic part with the semi-effect concentration(EC 50 ) of 59.6 mg L −1 , the central polarity part of inhibitory activity. The contents of chlorophyll a(Chl a) and phycobiliproteins(PBPs) of M. aeruginosa were decreased under the concentration of 200 mg L −1 ethyl acetate extract, which indicated that the photosynthesis of M. aeruginosa was inhibited. The consent of microcystins was lower compared to control under 200 mg L −1 . The contents of superoxide dismutase(SOD), malondialdehyde(MDA) and hydrogen peroxide(H 2 O 2 ) of cell pellets were firstly increased and then decreased, which suggested that the algal cells were seriously damaged by oxidation. The results indicated that the extracts of L. punctata had inhibitory effect on M. aeruginosa , and the ethyl acetate extract was the central part of the inhibitory substances, which affected photosynthesis and caused peroxidation damage to inhibit cell proliferation. These findings will be helpful for exploration and application of allelopathic effects of L. punctata in harmful algae control.
