Untargeted metabolomics combined with vitro antioxidant to comprehensively evaluate the effect of sodium sulfite immersion on the holistic quality of mung bean sprouts.

Mung bean sprouts are widely consumed as a seasonal fresh vegetable, renowned for their affordability and richness in antioxidants and bioactive compounds. This study employed ultra-high-performance liquid chromatogram-Q-Exactive HF mass spectrometry (UHPLC-QE-MS) and multivariate statistical analysis to comprehensively evaluate the chemical profile of mung bean sprouts following sulfite immersion. The findings revealed a significant alteration in the overall chemical composition of mung bean sprouts following sodium sulfite immersion.

Inhibitory effects of fucoidan from Laminaria japonica against some pathogenic bacteria and SARS-CoV-2 depend on its large molecular weight.

Fucoidan is a highly sulfated polysaccharide with a wide range of bioactivities, including anti-pathogenic activity. However, the relationship between structure and activity of fucoidan in inhibiting pathogen infections remains unclear. Here, different-molecular-weight fucoidans were prepared by photocatalytic degradation followed by membrane ultrafiltration, and their chemical structures and anti-pathogenic microbiota activity were compared.

Ginkgolide B produced endophytic fungus (Fusarium oxysporum) isolated from Ginkgo biloba.

To screen the presence of ginkgolide B-producing endophytic fungi from the root bark of Ginkgo biloba, a total of 27 fungal isolates, belonging to 6 different genus, were isolated from the internal root bark of the plant Ginkgo biloba. The fungal isolates were fermented on solid media and their metabolites were analyzed by TLC. The obtained potential ginkgolides-producing fungus, the isolate SYP0056 which was identified as Fusarium oxysporum, was successively cultured in the liquid fermentation media, and its metabolite was analyzed by HPLC.
