Article Abstract
The flavonoids from were extracted using flash extraction assisted by ultrasonic extraction with ethanol. Subsequently, macroporous resin was employed for the isolation and purification of these flavonoids, followed by an investigation into their antioxidant activity. The process conditions for the extraction of flavonoids from were designed and optimized using a one-way experiment combined with a response surface methodology. The optimal extraction conditions were determined as follows: the liquid-solid ratio was 20:1, ethanol volume fraction of 60%, ultrasound temperature of 60 °C, ultrasound time of 10 min and flash evaporation time of 60 s. The optimal extraction rate of flavonoids is 9.8 mg/g. In terms of separation and purification, a high-performance macroporous resin (HPD450 resin) with high purification efficiency was selected through static analysis and adsorption experiments. The optimal enrichment conditions were as follows: loading concentration of 0.06 mg/mL, optimal loading concentration of 20 mL, elution concentration of 70% and 76 mL, providing a reference for the further development and utilization of flavonoids.

Aster incisus is a perennial herbaceous plant belonging to the Asteraceae family, known for its pharmacologically active secondary metabolites. In this study, we conducted a comparative profiling and quantification of secondary metabolites in A. incisus extracts cultivated in two regions, Eumseong (AIE) and Inje (AII), using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and high-performance liquid chromatography with a variable wavelength detector (HPLC/VW).

Rhamnosyl Icariside II, a rare secondary flavonoid glycoside in , exhibits superior stability and bioactivity than the primary flavonoid glycosides. Converting primary flavonoid glycoside into Rhamnosyl Icariside II is desirable due to separate extraction methods are inefficient. In this study, a recyclable biphasic enzymatic hydrolysis process of extracts to produce high purity RIc was established and optimised.

Tofu from six different landraces of chilean common beans (Araucano, Cimarrón, Magnum, Peumo, Sapito, and Tortola) was prepared and analyzed for proximate and lipid composition, antioxidant capacity, and phenolic content. Tofu has higher protein and lipid content, lower carbohydrate and phenolic content, and shows antioxidant capacity. The highest total protein was found for tofu prepared from Cimarrón and Sapito beans.

Oral delivery of natural antioxidants represents a promising therapeutic strategy for ulcerative colitis (UC), yet their therapeutic efficacy is hindered by instability and poor accumulation at inflamed sites. To address this, we developed Galectin-3 (Gal-3)-targeted nanoparticles (ZDP-NPs) by encapsulating diosmetin within zein complexes modified with a galactose- and rhamnogalacturonan-I (RG-I)-rich pectin (PMTP, Mw: 228.8 kDa, DM: 34.
