Isoflavone-enriched soybean leaves (IESLs) were processed for drying, steaming, and fermentation, and bioactive compounds and biological activities were analyzed. During food processing, the content of fatty acids, water-soluble vitamins, total phenolics, total flavonoids, and isoflavone-aglycones increased from dried IESLs (DrIESLs) to fermented IESLs (FeIESLs). Especially, oleic acid (53.

Fermented and aged mountain-cultivated ginseng sprouts (FAMCGS) exhibit superior antioxidant and anti-inflammatory properties compared to mountain-cultivated ginseng sprouts (MCGS). However, the mechanisms behind these properties of FAMCGSE remain unclear. This study explores the anti-inflammatory effects of FAMCGS extract (FAMCGSE) on LPS-stimulated RAW 264.

Article Synopsis
  • This study analyzed the nutrients and antioxidant activities of different ratios (0%, 2.5%, 5%, and 10%) of mountain-cultivated ginseng (MCG) fermented with specific microorganisms.
  • It found that fermentation altered the content of isoflavones and ginsenosides, generally decreasing certain types while increasing others, particularly beneficial compounds like ginsenoside Rg3 and compound K.
  • The results suggest that higher ratios of MCG enhance the overall quality, antioxidant properties, and potential health benefits, making it valuable for food and pharmaceutical uses.

Article Synopsis
  • - This study examined how solid-state fermentation with various fungi affects the nutritional components, isoflavones, and antioxidant activities of Apios americana Medikus (AAM), highlighting significant increases in fatty acid and amino acid content post-fermentation.
  • - The fermentation process, particularly with the fungus Monascus purpureus, resulted in a remarkable increase in total fatty acids (up to 26.3 times) and improved mineral contents, demonstrating notable nutritional enhancement.
  • - Isoflavone glycosides in unfermented AAM were converted to more beneficial aglycone forms during fermentation, leading to higher total phenolic and flavonoid contents, which suggests that fermented AAM could be a valuable ingredient for food and medicinal

This study was the first to document the fluctuations of nutritional constituents, antioxidant capacities, and physicochemical characteristics during the aging processes of red ginseng sprouts (RGS) and black ginseng sprouts (BGS) from dried ginseng sprouts (DGS). Total ginsenoside levels differed with 54.72 (DGS) → 57.

In this study, we prepared fermented products of isoflavone-enriched soybean leaves (IESLs) and analyzed their nutrients, isoflavones, anti-obesity efficacy, and effects on gut microbiota. Fermented IESLs (FIESLs) were found to be rich in nutrients, especially lauric acid, oleic acid, and linoleic acid. In addition, the concentrations of most essential free amino acids were increased compared to those of IESLs.

The current research was the first to prove the existence of fluctuations in the metabolite constituents and antioxidant properties in different organs (leaves, stems, and roots) of the mountain-cultivated ginseng (MCG) plant during a two-month maturation period. Four metabolites, including fatty acids, amino acids, ginsenosides, and phenolic phytochemicals, exhibited considerable differences in organs and maturation times with the following order: leaves > stems > roots. The predominant metabolite contents were found in leaves, with fatty acid (1057.

  • Researchers developed high isoflavone-enriched soy leaves (IESLs) using the chemical inducer ethephon at varying concentrations (0, 150, and 300 μg/mL) to enhance the nutritional properties of underutilized soy leaves.
  • The study found that, while proximate composition and fatty acids showed minimal differences, free amino acids and water-soluble vitamins increased significantly with higher ethephon concentrations, with isoflavone levels rising dramatically.
  • The findings suggest that soy leaves treated with ethephon could serve as valuable ingredients for functional foods, cosmetics, and natural medicinal products due to their increased nutritional components.

Eighteen pesticide-degrading endophytic bacteria were isolated from the roots, stems, and leaves of healthy rice plants and identified through 16S rRNA gene sequencing. Furthermore, biochemical properties, including enzyme production, dye degradation, anti-bacterial activities, plant-growth-promoting traits, including N-fixation, P-solubilization, auxin production, and ACC-deaminase activities of these naturally occurring endophytic bacteria along with their four consortia, were characterized.

  • (L.) (Thunb.) A. A. Bullock is a halophyte medicinal plant found along the southwest coast of Korea, known for its pharmacological benefits and ability to produce secondary metabolites in response to salt stress.
  • In a hydroponic study, seedlings were treated with various NaCl concentrations (0-, 25-, 50-, 75-, and 100-mM) for eight weeks, revealing that concentrations below 100 mM did not significantly affect growth or chlorophyll fluorescence.
  • Results showed that higher NaCl levels decreased water potential and total amino acid content, while boosting the levels of specific compounds like proline, flavonoids, and myricetin glycosides, indicating that NaCl can

Interest in foods that promote inner beauty increases with increases in exposure to ultraviolet (UV) rays and with improvements in quality of life. This study was performed to evaluate the efficacy of fermented and aged mountain-cultivated ginseng sprouts (FAMCGSs), which have higher anti-inflammatory and antioxidant effects compared to mountain-cultivated ginseng sprouts (MCGSs), as an inner beauty enhancing food. The effect of orally administered FAMCGSs on UV type B (UVB) radiation-induced skin aging was investigated in a hairless mouse model through analyzing skin parameters including epidermal thickness, transepidermal water loss (TEWL), roughness, moisture, elasticity, and collagen contents.

The association between asthma and oxidative stress remains controversial. Oxidative stress-induced ferroptosis has not been extensively studied in asthma models. This study was performed to investigate the anti-asthmatic and anti-ferroptotic effects of fermented and aged ginseng sprouts (FAGS) with enhanced antioxidant activity and its main component, compound K (CK), in a mouse model of ovalbumin (OVA)-induced allergic asthma.

Alcoholic liver damage is caused by ethanol and its oxidized intermediates, and endotoxin-induced acute liver failure is mediated by apoptosis and inflammation. We investigated whether extracts of sprouts of (SG) attenuate alcohol or endotoxin-induced acute liver injury in mice. Whole SG contains eight times more ginsenosides than the root and, because it grows quickly ([Formula: see text]30 days) without using pesticides, the whole-plant can be harvested.
