2023年5月1日 · In this study, metal-polyphenol nanoformulations (Cu-Epigallocatechin-3-gallate (Cu-EGCG) nanosheets) were synthesized through the coordination interaction between EGCG and copper ions, which possessed the antioxidant effect of EGCG and anti-inflammatory of Cu 2+.

2022年1月15日 · UV–vis spectroscopy was applied to analyze the loading rate of EGCG. TEM, DLS, TGA, FTIR, and XRD were performed for the characterization, followed with investigation of the antibacterial and antioxidant properties of the nanocomposite.

2023年7月5日 · To improve epigallocatechin gallate (EGCG)’s inhibition on α-glucosidase, Mn (II)-EGCG was prepared and characterized by Fourier transform infrared (FT-IR), mass spectrometry (MS), X-ray diffraction (XRD), nuclear magnetic resonance hydrogen (1 H-NMR), and thermogravimetric analysis (TGA).

Vesicular entrapped ellagic acid exhibited a significant reduction in reactive oxygen species on UVA-irradiated HaCaT cells, indicating its efficacy as an antioxidant agent in contrasting...

XRD results revealed no form conversion of EGCG in its transfersomal form. The optimized transfersomes were found to increase the cell viability and reduce the lipid peroxidation, intracellular ROS and expression of MMPs in HaCaT cells.

2024年3月22日 · The XRD pattern (Fig. 3c) of pure EGCG had defined sharp peaks at 2Ø angles such as 15.51°, 16.86°, 20.64°, 21.45°, 22.44°, 24.46°, 25.78° and 29.06° which confirms the crystalline nature of the EGCG which was reduced in case of nanoparticles such as unmodified nanoparticles (16.98° and 22.88°) and modified nanoparticles (22.50 ...

为提高表没食子儿茶素没食子酸酯 (egcg) 对α-葡萄糖苷酶的抑制作用，制备了 mn (ii)-egcg，并采用傅里叶变换红外 (ft-ir)、质谱 (ms)、x 射线衍射 (xrd)、核磁共振氢 ( 1 h-nmr) 和热重分析 (tga)。

2017年2月3日 · The XRD pattern of plain EGCG (Figure 3A) revealed the presence of strong diffraction peaks 16.15° (435.12 cps), 21.73° (926.77 cps) and 22.29° (1298.29 cps).

2024年11月1日 · Herein, we prepared a cobalt monoatomic intercalated M/E0.1-Co catalytic separation membrane by mild reduction of epigallocatechin-3-gallate (EGCG). EGCG not only connects the MXene lamellae during filtration through strong hydrogen bonding, but also protects the chemical stability of the MXene substrate through its antioxidant ability.

2024年7月24日 · The encapsulated EGCG was characterized for its morphology, thermal, and crystalline properties using FESEM, DSC, XRD, and Fourier transform infrared (FTIR) studies. The bioactivity of EGCG to reduce gut cholesterol was studied using in …
