Unveiling the Chemical Composition, Bioactive Profile and Antioxidant Capacity of Dried Egyptian Jew's Mallow Stems as a Promising Anticancer Agent.

Phytochemicals from waste materials generated by agricultural and industrial processes have become globally significant due to their accessibility and potential effectiveness with few side effects. These compounds have essential implications in both medicine and the economy. Therefore, a quantitative analysis of the phytochemical profile, sugar types, and water-soluble vitamins of dried Corchorus olitorius L."DJMS" extract (dried Jew's mallow stem) was carried out with HPLC. In addition, the chemical composition, TPC, chlorophyll a and b, beta-carotene, and antioxidant effect using DPPH were investigated. Furthermore, the anticancer activity of the DJMS was evaluated by SRB assay using Huh-7 and MDA-MB-231 cell lines. In the quantitative study, DJMS extract showed a high antioxidant potential (67%) due to its content of bioactive compounds such as TPC (276.37 mg 100 g-1) and chlorophyll a and b (20.31, 12.02 mg 100 g-1, respectively), as well as some vitamins and minerals such as B-complex (B12; 146.8 mg 100 g-1 and vitamin C 6.49 mg 100 g-1) and selenium (<0.2 µg kg-1). Moreover, the main sugar types found were sucrose and stachyose, which recorded 9.23 and 6.25 mg 100 g-1, respectively. Identifying phenolic and flavonoids showed that the major components were ellagic acid (4905.26 µg kg-1), ferulic acid (3628.29 µg kg-1), chlorogenic acid (3757.08 µg kg-1), luteolin-7-O-glucoside (4314.48 µg kg-1), naringin (4296.94 µg kg-1) and apigenin-6-rhamnose-8 glucoside (3078.87 µg kg-1). The dried stem extract showed significant MDA-MB-231 inhibition activity and reached 80% at a concentration of 1000 µg/mL of DJMS extract, related to the content of phytochemical components such as isoflavones like genistein (34.96 µg kg-1), which had a tremendous anticancer effect. Hence, the stem of Jew's mallow (which is edible and characterized by its viability and low production cost) possesses the capacity to serve as a pharmaceutical agent for combating cancer owing to its abundance of bioactive components.

Dietary iron or inulin supplementation alters iron status, growth performance, intramuscular fat and meat quality in finisher pigs.

Forty LW × L pigs (20 boars and 20 gilts) (51.1 ± 0.41 kg) were allocated to a 2 × 2 × 2 factorial design with the respective factors being supplemental organic iron (Fe, 0 and 500 mg/kg), inulin (In, 0 and 50 g/kg) and sex (boars and gilts). After 5 weeks the animals were transported to an abattoir before slaughter and collection of samples. Serum iron was increased by supplemental Fe (28.4 v. 30.9 µmol/L, P = 0.05), although there was an interaction (P = 0.03) such that pigs fed diets with In had lower serum Fe concentrations than those without In (26.8 v. 32.3 µmol/L). Boars had lower (P < 0.01) haemoglobin (116 vs 125), haematocrit (36.7 v. 39.7%) and erythrocyte (6.6 v. 7.1 × 106/mL) concentrations than gilts. Dietary In increased liveweight gain (795 v. 869 g/d, P < 0.02) and carcass weight (62.9 v. 65.2 kg, P < 0.02). Dietary Fe or In supplementation did not improve muscle Longissimus thoracis et lumborum (LTL) total Fe concentration (P > 0.05). Muscle non-heme Fe concentration was higher in Fe-supplemented pigs (P < 0.04) and gilts (P < 0.05) than their counterparts. Muscle heme Fe concentration was greater (3.04 vs 2.51, P < 0.05) in boars than in gilts. The LTL marbling score was greater (P < 0.01) for In-supplemented pigs, and the response was more notable when Fe and In were fed together. These data show that dietary supplementation of Fe increased serum Fe and muscle non-heme Fe concentrations. Supplementation of In at 5% in the diet of finisher pigs improved liveweight gain and the marbling score of pork.

Can conventional forages be replaced with cotton plant (Gossypium hirsutum) wastes in fattening lambs? Laboratory and animal studies.

The cotton plant (Gossypium hirsutum) is a shrub native to many arid and semi-arid regions around the world, while the nutritional value of its wastes has been less scientifically investigated. Different components of whole cotton plant wastes (WCPW) including leaf blade, cotton pod, stem, root, bract, petiole, and cottonseed were evaluated for their nutritional values by standard laboratory methods. After that, we tested the WCPW for partial substitution (0, 20, 40, and 60% substitution or 0, 10, 20, and 30% of dietary dry matter (DM)) with dietary common forage in a completely randomized design with 32 feedlot male lambs for 90 days. A diverse range of chemical and mineral compositions was found among the different WCPW's components. The cottonseed had the highest crude protein (CP) and ether extract (EE) contents, while the lowest neutral detergent fiber (NDF) and acid detergent fiber (ADF) were observed in the leaf blade (P < 0.0001). The highest contents of calcium, phosphorus, sodium, magnesium, and iron were also observed in the leaf blade (P < 0.0001). Higher potential gas production, in vitro organic matter digestibility (OMD), in vitro dry matter digestibility (DMD), and total volatile fatty acids (TVFA) were also related to the leaf blade (P < 0.0001). Bract had the highest acid-base buffering capacity (P < 0.0001). The lambs fed on 30% of dietary DM with WCPW exhibited lower final body weight (BW), average daily gain (ADG), CP or NDF digestibility, ruminal TVFA, propionate, plasma total protein, and higher feed conversion ratio (FCR) compared to the control group. Generally, WCPW can be substituted up to 40% of common forages (or 20% of diet DM) without any adverse effect on growth performance and blood metabolites of feedlot lambs, especially during feed shortages.

Hepatoprotective Effect of Medicine Food Homology Flower Saffron against CCl4-Induced Liver Fibrosis in Mice via the Akt/HIF-1α/VEGF Signaling Pathway.

Liver fibrosis refers to a complex inflammatory response caused by multiple factors, which is a known cause of liver cirrhosis and even liver cancer. As a valuable medicine food homology herb, saffron has been widely used in the world. Saffron is commonly used in liver-related diseases and has rich therapeutic and health benefits. The therapeutic effect is satisfactory, but its mechanism is still unclear. In order to clarify these problems, we planned to determine the pharmacological effects and mechanisms of saffron extract in preventing and treating liver fibrosis through network pharmacology analysis combined with in vivo validation experiments. Through UPLC-Q-Exactive-MS analysis, a total of fifty-six nutrients and active ingredients were identified, and nine of them were screened to predict their therapeutic targets for liver fibrosis. Then, network pharmacology analysis was applied to identify 321 targets for saffron extract to alleviate liver fibrosis. Functional and pathway enrichment analysis showed that the putative targets of saffron for the treatment of hepatic fibrosis are mainly involved in the calcium signaling pathway, the HIF-1 signaling pathway, endocrine resistance, the PI3K/Akt signaling pathway, lipid and atherosclerosis, and the cAMP signaling pathway. Based on the CCl4-induced liver fibrosis mice model, we experimentally confirmed that saffron extract can alleviate the severity and pathological changes during the progression of liver fibrosis. RT-PCR and Western blotting analysis confirmed that saffron treatment can prevent the CCl4-induced upregulation of HIF-1α, VEGFA, AKT, and PI3K, suggesting that saffron may regulate AKT/HIF-1α/VEGF and alleviate liver fibrosis.

Effect of Yarrowia lipolytica yeast biomass with increased kynurenic acid content on selected metabolic indicators in mice.

Background: The unconventional yeast species Yarrowia lipolytica is a valuable source of protein and many other nutrients. It can be used to produce hydrolytic enzymes and metabolites, including kynurenic acid (KYNA), an endogenous metabolite of tryptophan with a multidirectional effect on the body. The administration of Y. lipolytica with an increased content of KYNA in the diet may have a beneficial effect on metabolism, which was evaluated in a nutritional experiment on mice. Methods: In the dry biomass of Y. lipolytica S12 enriched in KYNA (high-KYNA yeast) and low-KYNA (control) yeast, the content of KYNA was determined by high-performance liquid chromatography. Then, proximate and amino acid composition and selected indicators of antioxidant status were compared. The effect of 5% high-KYNA yeast content in the diet on the growth, hematological and biochemical indices of blood and the redox status of the liver was determined in a 7-week experiment on adult male mice from an outbred colony derived from A/St, BALB/c, BN/a and C57BL/6J inbred strains. Results: High-KYNA yeast was characterized by a greater concentration of KYNA than low-KYNA yeast (0.80 ± 0.08 vs. 0.29 ± 0.01 g/kg dry matter), lower content of crude protein with a less favorable amino acid composition and minerals, higher level of crude fiber and fat and lower ferric-reducing antioxidant power, concentration of phenols and glutathione. Consumption of the high-KYNA yeast diet did not affect the cumulative body weight gain per cage, cumulative food intake per cage and protein efficiency ratio compared to the control diet. A trend towards lower mean corpuscular volume and hematocrit, higher mean corpuscular hemoglobin concentration and lower serum total protein and globulins was observed, increased serum total cholesterol and urea were noted. Its ingestion resulted in a trend towards greater ferric-reducing antioxidant power in the liver and did not affect the degree of liver lipid and protein oxidation. Conclusions: The improvement of the quality of Y. lipolytica yeast biomass with increased content of KYNA, including its antioxidant potential, would be affected by the preserved level of protein and unchanged amino acid profile. It will be worth investigating the effect of such optimized yeast on model animals, including animals with metabolic diseases.

Implications of vitamin D for flesh quality of grass carp (Ctenopharyngodon idella): antioxidant ability, nutritional value, sensory quality, and myofiber characteristics.

BACKGROUND: Muscle represents a unique and complex system with many components and comprises the major edible part of animals. Vitamin D is a critical nutrient for animals and is known to enhance calcium absorption and immune response. In recent years, dietary vitamin D supplementation in livestock has received increased attention due to biological responses including improving shear force in mammalian meat. However, the vitamin D acquisition and myofiber development processes in fish differ from those in mammals, and the effect of vitamin D on fish flesh quality is poorly understood. Here, the influence of dietary vitamin D on fillet quality, antioxidant ability, and myofiber development was examined in grass carp (Ctenopharyngodon idella). METHODS: A total of 540 healthy grass carp, with an initial average body weight of 257.24 ± 0.63 g, were allotted in 6 experimental groups with 3 replicates each, and respectively fed corresponding diets with 15.2, 364.3, 782.5, 1,167.9, 1,573.8, and 1,980.1 IU/kg vitamin D for 70 d. RESULTS: Supplementation with 1,167.9 IU/kg vitamin D significantly improved nutritional value and sensory quality of fillets, enhancing crude protein, free amino acid, lipid, and collagen contents; maintaining an ideal pH; and reducing lactate content, shear force, and cooking loss relative to respective values in the control (15.2 IU/kg) group. Average myofiber diameter and the frequency of myofibers > 50 µm in diameter increased under supplementation with 782.5-1,167.9 IU/kg vitamin D. Levels of oxidative damage biomarkers decreased, and the expression of antioxidant enzymes and nuclear factor erythroid 2-related factor 2 signaling molecules was upregulated in the 1,167.9 IU/kg vitamin D treatment compared to respective values in the control group. Furthermore, vitamin D supplementation activated cell differentiation by enhancing the expression of myogenic regulatory factors and myocyte enhancer factors compared to that in the control group. In addition, supplementation with 1,167.9 IU/kg vitamin D improved protein deposition associated with protein synthesis molecule (target of rapamycin) signaling and vitamin D receptor paralogs, along with inhibition of protein degradation (forkhead box protein 1) signaling. CONCLUSIONS: Overall, the results demonstrated that vitamin D strengthened antioxidant ability and myofiber development, thereby enhancing nutritional value and sensory quality of fish flesh. These findings suggest that dietary vitamin D supplementation is conducive to the production of nutrient-rich, high quality aquaculture products.

Enhancing meat quality of weaned piglets with the dietary incorporation of Ulva lactuca and carbohydrases supplementation.

The impact of the dietary incorporation of 7% Ulva lactuca, a green seaweed, on the quality and nutritional value of piglet's meat was assessed. U. lactuca is rich in nutrients and bioactive compounds but its cell wall is composed of complex polysaccharides that reduce their bioavailability. Therefore, the effect of supplementing piglet diets with exogenous carbohydrases was also assessed here. A total of 40 male weaned piglets were divided into four dietary groups, each with 10 piglets: control (wheat, maize and soybean meal-based diet), UL (7% U. lactuca replacing the control diet), UL + R (UL and 0.005% Rovabio®), and UL + E (UL and 0.01% ulvan lyase). The piglets were fed the diets for 2 weeks. The results showed that incorporating U. lactuca in piglet diets did not influence most of the meat quality traits (P > 0.05). However, the incorporation of U. lactuca with the commercial carbohydrase (UL + R) increased the amount of the docosahexaenoic acid (DHA; 22:6n-3) in their meat (P = 0.011) compared with the control, by 54%. In addition, meat from piglets fed seaweed diets showed a nearly two-fold increase in iodine contents (P < 0.001). Meat tenderness, juiciness and overall acceptability of piglets fed the control diet and the UL diet were lower than those fed the diets containing seaweed and carbohydrases (P < 0.001). Overall, the findings indicate that 7% U. lactuca in the diets of weaned piglets had no major detrimental effects on meat quality and their carbohydrase supplementation has the potential to improve meat sensory traits.

Nutritional Composition and Pharmacological Activity of Musa balbisiana Colla Seed: An Insight into Phytochemical and Cellular Bioenergetic Profiling.

Musa balbisiana Colla belongs to the family Musaceae which is well-known for its nutritional and pharmacological properties. Here, we have analysed the phytochemical content and evaluated the nutritional, antioxidant, anti-glycation, α-amylase, and α-glucosidase inhibition potential. Moreover, for the first time, we have studied the bioenergetic profiles of the bioactive fractions of M. balbisiana seeds extract against oxidative stress-related mitochondrial and cellular dysfunction using XFe24 extracellular flux analyzer. M. balbisiana seeds have high nutritional values with significant levels of carbohydrates, starch, protein, and minerals (Ca, Na, Mg, Cu, Fe, and Zn). Bioactivity-guided fractionation of the methanolic extract of M. balbisiana seeds revealed that the ethyl acetate fraction (EAF) showed the highest antioxidant, anti-glycation, and phytochemical content as compared to other fractions. Moreover, the EAF showed a lower α-amylase inhibition and a higher α-glucosidase inhibitory activity. Most importantly, our GC-MS analyses of EAF revealed the presence of unique and previously unreported 14 phytochemical compounds. A strong correlation between the biological activities and total phenolic/tannin content was observed. In addition, the bioactive fraction of M. balbisiana seeds (EAF) improved the bioenergetic profiles of free fatty acid-induced oxidative stress with a concomitant increase in ATP production, and respiratory and glycolytic capacity. Altogether, our findings suggest that M. balbisiana seeds can be used as a natural supplement to boost antioxidant levels and combat oxidative stress and non-enzymatic glycation.

Thymus satureioides Coss.: Mineral Composition, Nutritional Value, Phytochemical Profiling, and Dermatological Properties.

Zaitra, Thymus satureioides, is an aromatic plant with a long history of use in traditional medicine. In this study, we assessed the mineral composition, nutritional value, phytocontents, and dermatological properties of the aerial parts of T. satureioides. The plant contained high contents of calcium and iron, moderate levels of magnesium, manganese, and zinc, and low contents of total nitrogen, total phosphorus, total potassium, and copper. It is rich in several amino acids, including asparagine, 4-hydroxyproline, isoleucine, and leucine, and the essential amino acids account for 60.8%. The extract contains considerable amounts of polyphenols and flavonoids (TPC = 118.17 mg GAE/g extract and TFC = 32.32 mg quercetin/g extract). It also comprises 46 secondary metabolites, identified through LC-MS/MS analysis, belonging to phenolic acids, chalcones, and flavonoids. The extract elicited pronounced antioxidant activities, inhibited the growth of P. aeruginosa (MIC = 50 mg/mL), and reduced biofilm formation by up to 35.13% using the » sub-MIC of 12.5 mg/mL. Moreover, bacterial extracellular proteins and exopolysaccharides were diminished by 46.15% and 69.04%, respectively. Likewise, the swimming of the bacterium was impaired (56.94% decrease) in the presence of the extract. In silico, skin permeability and sensitization effects revealed that out of the 46 identified compounds, 33 were predicted to be exempt from any skin sensitivity risk (Human Sensitizer Score ≤ 0.5), while extensive skin permeabilities were observed (Log Kp = -3.35--11.98 cm/s). This study provides scientific evidence about the pronounced activities of T. satureioides, supports its traditional uses, and promotes its utilization in the development of new drugs, food supplements, and dermatological agents.

Nutritional, biological, and structural properties of bioactive peptides from bellflower, Persian-willow, and bitter-orange pollens.

In this study, the composition of amino acids, nutritional characteristics, degree of hydrolysis (DH), antioxidant properties, and antibacterial activity of proteins and hydrolysates of bellflower (Campanula latifolia), Persian willow (Salix aegyptiaca), and bitter orange (Citrus aurantium L.) were investigated under the influence of different proteases (Alcalase: Al, trypsin: Tr, pancreatin: Pa, and pepsin: Pe). Evaluation of the structural features of the proteins showed amide regions (amide A, B, I-III) and secondary structures. Hydrophobic amino acids (∼38%), antioxidants (∼21%), and essential types (∼46%) form a significant part of the structure of flower pollen. The digestibility and nutritional quality (PER) of the hydrolyzed samples (CP: 1.67; CA: 1.89, and PW: 1.93) were more than the original protein. Among proteins and peptides, the highest degree of hydrolysis (34.6%: Al-PWH), inhibition of free radicals DPPH (84.2%: Al-CPH), ABTS (95.2%: Pa-CPH), OH (86.7%: Tr-CAH), NO (57.8%: Al-CPH), reducing power (1.31: Pa-CPH), total antioxidant activity (1.46: Pa-CPH), and chelation of iron ions (80%: Al-CPH and Al-CAH) and copper (50.3%: Pa-CAH) were affected by protein type, enzyme type, and amino acid composition. Also, the highest inhibition of the growth of Escherichia coli (25 mm) and Bacillus cereus (24 mm) were related to CP and PW hydrolysates, respectively. The results of this research showed that hydrolyzed flower pollens can be used as a rich source of essential amino acids as well as natural antioxidants and antibacterial in food and dietary products. PRACTICAL APPLICATION: Enzymatic hydrolysis of Campanula latifolia, Persian willow, and Citrus aurantium pollen proteins was performed. The hydrolyzed ones had high nutritional quality and digestibility (essential amino acids and PER index). Antioxidant properties and chelation of metal ions of peptides were affected by the type of protein and enzyme. The hydrolysates showed inhibitory activity against the growth of Esherichia coli and Bacillus cereus.

Wild vs. Cultivated Zingiber striolatum Diels: Nutritional and Biological Activity Differences.

Compositional, functional, and nutritional properties are important for the use-value assessments of wild and cultivated edible plants. The aim of this study was to compare the nutritional composition, bioactive compounds, volatile compounds, and potential biological activities of cultivated and wild Zingiber striolatum. Various substances, such as soluble sugars, mineral elements, vitamins, total phenolics, total flavonoids, and volatiles, were measured and analyzed using UV spectrophotometry, ICP-OES, HPLC, and GC-MS methods. The antioxidant capacity of a methanol extract of Z. striolatum, as well as the hypoglycemic abilities of its ethanol and water extracts, were tested. The results showed that the contents of soluble sugar, soluble protein, and total saponin in the cultivated samples were higher, while the wild samples contained higher amounts of K, Na, Se, vitamin C, and total amino acids. The cultivated Z. striolatum also showed a higher antioxidant potential, while the wild Z. striolatum exhibited a better hypoglycemic activity. Thirty-three volatile compounds were identified using GC-MS in two plants, with esters and hydrocarbons being the main volatile compounds. This study demonstrated that both cultivated and wild Z. striolatum have a good nutritional value and biological activity, and can be used as a source of nutritional supplementation or even in medication.

Assessment of physicochemical parameters, bioactive compounds, biological activities, and nutritional value of the most two commercialized pollen types of date palm (Phoenix dactylifera L.) in Morocco.

The pollen of date palm (Phoenix dactylifera L.) is known for its nutritional value and implications as a health-promoting component. Due to its low cost, date palm pollen crushed with its spadix is more widely commercialized and used in Morocco than pure date palm pollen free of spadix. Thus, this study aimed to assess the physicochemical and phytochemical parameters, biological activities, and nutritional value of the two pollen types: Pure date palm pollen and date palm pollen crushed with its spadix. Various physicochemical parameters were determined, including humidity, water activity (aw), total soluble solids, ash content, and color parameters (L*, a*, b*, C*ab, and hab). Additionally, the phenolic compound profiles were analyzed, and the in vitro antioxidant, enzyme inhibitory, and antidiabetic activities were assessed for both pure date palm pollen and date palm pollen crushed with its spadix. Furthermore, the nutritional value was evaluated by determining protein and carbohydrate contents, and mineral and fatty acid profiles. The results have revealed that pure date palm pollen had higher humidity, aw, L*, and hab color parameters than date palm pollen crushed with its spadix, but lower total soluble solid and ash contents. The main phenolic compounds in pure date palm pollen were ellagic acid, rutin, fisetin, and quercetin, whereas date palm pollen crushed with its spadix contained mainly catechin, chlorogenic acid, p-coumaric acid, ferulic acid, and rutin. Moreover, pure date palm pollen showed greater in vitro antioxidant activity, while date palm pollen crushed with its spadix had higher enzyme inhibitory and antidiabetic activities. PDPS was the richest source of proteins, carbohydrates, minerals, and saturated fatty acids, while date palm pollen crushed with its spadix was a better source of unsaturated fatty acids, which are mainly represented by linoleic acid. In conclusion, although date palm pollen crushed with its spadix is the most widely consumed type, its nutritional value is lower than that of pure date palm pollen. Thus, pure date palm pollen could potentially serve as a better source of many bioactive compounds, making it a viable supplement for various health applications.

Insect tea originated from ethnic minority regions in Southwest China: A review on the types, traditional uses, nutrients, chemistry and pharmacological activities.

ETHNOPHARMACOLOGICAL RELEVANCE: Insect tea is a special non-Camellia tea produced from the feces of insects in ethnic minority regions in Southwest China. Insect tea was recorded to have the traditional functions to treat summer heat, dampness, digestive disturbance, excessive phlegm, shortness of breath and otitis, etc. AIM OF THIS STUDY: This review provides an updated and comprehensive review of insect tea on the tea types, host plants, tea-producing insects, producing process, traditional uses, nutritional values, chemistry, pharmacological activities, biological safety and toxicity. Moreover, the general challenges and the possible suggestions on insect tea in future were also discussed. MATERIALS AND METHODS: The relevant literature on insect tea was obtained from scientific database, including Elsevier, PubMed, Springer, Wiley, Web of Science, Google Scholar, SciFinder, China National Knowledge Infrastructure (CNKI), Baidu Scholar, Wanfang Database, etc. In addition, pertinent information available in Ph.D theses, MSc. dissertations, books, records, and some classical Chinese herbal literature were also included. The references cited in this review were up to September 2022. RESULTS: Insect tea has been traditionally used as popular beverage with various medicinal functions in the ethnic minority regions in Southwest China for centuries. At present, ten types of insect teas are recorded in different regions. Ten species tea-producing insect and fifteen species host plants are used to in the production of the tea. Insect teas were rich in various nutrients including proteins, carbohydrates, fat, minerals, dietary fiber and Vitamins. A total of 71 compounds have been isolated from insect teas, mainly including flavonoids, ellagitannins, chlorogenic acids and other phenolic compounds as well as the alkaloids. Modern studies demonstrated that insect tea had a variety of pharmacological activities in vitro and in vivo, such as anti-diabetic, lipid-lowing and anti-hypertensive, hepato-protective, gastro-intestinal promoting, anti-cancer, anti-mutagenic, antioxidant, and anti-aging activity, etc. Moreover, existing experimental results showed that insect teas are non-toxicity and biological safety. CONCLUSION: Insect tea is a unique and niche product originated in the ethnic minority regions of Southwest China with various health-promoting benefits. Phenolics including flavonoids, ellagitannins, chlorogenic acids were reported as the main chemical constituents identified from insect tea. Multiple pharmacological activities of insect tea have been reported, which indicated that it had great potential for further development and application as drugs and health-promoting products. However, more studies on the tea-producing insects, host plants, chemistry and pharmacological activity of insect tea, as well as the toxicology should be further investigated.
