To explore the antioxidant activity of enzymatic hydrolysates of from Dalian and preliminarily elucidate their mechanisms of action both and . Samples were hydrolysed using alcalase, protamex, and neutrase. 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays showed that the alcalase hydrolysate had the highest antioxidant activity, with IC values of 4.

This study aimed to optimize the ultrasonic/microwave-assisted extraction (UAME) technique of polysaccharides (EAP-UM) by response surface methodology (RSM). The optimum conditions include: solid-liquid ratio of 1:23 g/mL, ultrasonic power of 252 W, microwave power of 417 W, and extraction time of 11 min. Under these conditions, the yield of polysaccharides reached 7.

is a medicinal plant native to East Asia with its diverse therapeutic potentials. In particular, the antioxidant effect of this plant is well known, but there has been little research on the antioxidant effect according to different habitats or ages. In this study, we evaluated the proximate composition, mineral, saponin, rutin, total phenolic and flavonoid contents, and antioxidant activities of leaf extracts of plants cultivated from two different regions (New Zealand and Jeju Island, Korea) and of the same age (2-year-old plants).

Aims: We develop and evaluate copper-based metal-organic frameworks (Cu-MOFs) incorporating cromolyn as a linker to enhance structural stability, drug delivery efficiency, and therapeutic potential, particularly for breast cancer treatment.
Materials & Methods: Two Cu-MOF formulations were synthesized: Cu-MOFs-BDC-DOX (using terephthalic acid) and Cu-MOFs-CROMO-DOX (using cromolyn as a linker). Characterization was performed using SEM/TEM for morphology, and FTIR, XRD, and TGA to confirm structural integrity.

Although metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have been extensively used as fluorescent-based antibiotic sensors, newly developed hydrogen-bonded organic frameworks (HOFs) are largely unexplored toward this direction. To realize this, the luminescent HOFs must be stable in water as the analytes are mostly found in water-based effluents in environments. In addition, HOFs should be equipped with specific recognition sites in order to direct the discrimination among the antibiotics.
