Coix seed is a nutrient-rich food and traditional Chinese medicine with anti-inflammatory and analgesic properties. Polysaccharides from Coix seed have been rarely investigated for structure and activities. In this study, the analgesic and anti-inflammatory effects were investigated and . The results showed that Coix seed had a significant influence on reducing the number of writhing, increasing the pain threshold and alleviating the swelling degree caused by acute inflammation. Column chromatography was used to obtain two active compounds of Coix seed. Compound 1 was (1→6)-α-glucan with a molecular weight of 6.81 × 10 Da. The chemical connection of compound 2 was as follows: α-Frup (2→ [1)-α-Glcp (6]→1)-α-Glcp (4→1)-α-Glcp, which was isolated in Coix seed for the first time. LPS-induced inflammation in RAW264.7 cells was well inhibited by compounds. These findings offered a preliminary investigation into the analgesic and anti-inflammatory properties of Coix seed, which may be helpful for application.

The toughening coix seed oil (CSO) high internal phase Pickering emulsion (CSO-HIPES) and gel (CSO-HIPESG) comprised of carrageenan (CR)/super-deamidated-gluten (SDG) micro-particles (CR/SDG) were investigated via acid-heat induction. Results showed polysaccharide natural deep eutectic solvent (P-NADES) by citric acid-glucose-carrageenan ((CGCR), molar ratio at 1:1:0.035) was the crucial for the preparation of SDG (deamidation degree, 99.

A manganese porphyrin wrapped DNA dendrimer (Mn-DD) was developed through enzyme-free DNA self-assembly and simple and mild groove binding of porphyrin. The Mn-DD not only possessed plenty of manganese porphyrin to amplify the chemiluminescence (CL) signal, but also can be modified with diverse groups via DNA hybridization. Combined with an immunosensor array, Mn-DD can be utilized for CL immunoassay of multiple mycotoxins as a universal tag.

Chang-Wei-Qing (CWQ) is a widely recognized Traditional Chinese Medicine (TCM) formulation composed of Astragalus, Codonopsis, Atractylodes, Poria, Coix seed, Akebia trifoliata Koidz, Sargentodoxa cuneata, and Vitis quinquangularis Rehd. This formulation has garnered significant interest for its positive effects in mitigating colorectal cancer, and when combined with PD-1, it affects some gut microbiota associated with tumor infiltrating lymphocytes cells. However, the biological rationale underlying the suppression of colitis-associated colorectal cancer (CAC) in AOM/DSS-treated mice by CWQ combined with PD-1 inhibitor remains to be explored.

The transfer of natural antioxidants from feed to milk has become a research hotspot. Polyphenols are a source of potent natural antioxidants that may play important roles in improving antioxidant activity and milk quality in dairy goats. The aim of this study was to evaluate the effects of polyphenol-rich Coix seed extract (CSE) on rumen fermentation, milk production, fatty acid profile, antioxidant activity, and polyphenol content in milk from lactating dairy goats.

Coix seed-natto (CS-natto) is a nutritious food rich in various functional components such as nattokinase (NK), and the strains' fermentation is crucial for enhancing its quality. This work utilized Bacillus natto GUTU09 (B9) and Bifidobacterium animalis subsp. lactis BLH1 or BLH6 to ferment soybeans that were soaked in a saccharified liquid made from CS, resulting in the preparation of CS-natto, studied the physicochemical and functional characteristics during fermentation, and analyzed the correlation of various indicators.
