Research ArticleOpen accessIn the keywordsQualitative Analysis of the Chemical Composition of Cinnamomum tamala leaves and Biological ActivityQianwen Gong, Pin Chen, Linyang Wang, Shuge TianCinnamomum tamala (Buch.-Ham.) Nees and Ebermaier. (Lauraceae) is a less explored medicinal plant in Uyghur medicine, with limited knowledge about its non-volatile compounds. We utilized chemical pre-screening in conjunction with UPLC-Q-Orbitrap-MS to analyze the phytochemical makeup of C. tamala leaves. Total polyphenols were measured using the Folin-Ciocalteu method, while total flavonoids were quantified through NaNO2-Al (NO3)3 colorimetric analysis across four … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 659 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Zein-Fucoidan Nanoparticles Loaded with Curcumin on the Maillard Reaction Between Casein and LactoseShiyang Li, Yufan Liu, Yuanda Song et al.The influence of curcumin-encapsulated Zein-Fucoidan Nanoparticles (CZFNPs) on the formation of Maillard reaction products (MRP) at the early, intermediate, and advanced stages in a casein-lactose (CN-Le) reaction system was systematically studied. As controls, the effects of Zein-Fucoidan Nanoparticles (ZFNPs) and free Curcumin (Cur) were also evaluated. The results showed that CZFNPs effectively inhibited the formation of fructosamine, Glyoxal (GO), as … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 30 Jul 2026 · 605 accessesView PDF Cite
