Summary: In this study, two homogeneous polysaccharides (APS-A1 and APS-B1) were isolated from Astragalus membranaceus and their chemical structures were characterized. APS-A1 had a 1,4-alpha-D-Glcp backbone with a 1,4,6-alpha-D-Glcp branch every ten residues, while APS-B1 was a heteropolysaccharide composed of glucose, galactose, and arabinose. Bioactivity assays showed that both APS-A1 and APS-B1 exhibited potential anti-inflammatory activity.

Summary: Polysaccharides obtained from Polygonatum sibiricum (PSP) were purified and characterized in this study. The PSP1 sample had the highest content and best solubility. The main sugar residue linkages were identified as 1)-beta-D-Fruf-(2 -> 1)-beta-D-Fruf-(2 -> 1), 1 -> -beta-D-Fruf-(2 -> 6)alpha-D-Glcp (1 ->,-> 4)-beta-D-Manp-(1 -> 4)-beta-D-Manp-(1 -> and -> 6)-beta-D-Glcp-(1 -> 4)-beta-D-Manp-(1 ->. Branch chain analysis revealed the presence of -> 1,6)-beta-D-Fruf-(2 ->, beta-D-Fruf-(2 ->,-> 1,6)-beta-D-Fruf-(2 ->,-> 6)-beta-D-Fruf(2 -> linkages, with the link site at position C-6. In vitro antioxidant activity tests showed that PSP1 had scavenging effects on DPPH, hydroxyl radical, superoxide anion radical, and exhibited a specific chelating ability for ferrous ions. These findings suggest that P. sibiricum polysaccharides may possess potential antioxidant properties.

Summary: The study found that ultrasonic irradiation at 40 kHz in the MFU mode resulted in a larger increment in the galactumnic acid content of CP, but greater reductions in its intrinsic viscosity, molecular weight, and degree of methoxylation than in the SDFU modes. Ultrasonic frequency had no significant influence on the main CP chain, but rather on its neutral sugar side chains. Additionally, ultrasound treatment at different frequency modes effectively enhanced the thermal stability of CP, but remarkably lowered its shear thinning fluid behavior and liquid-like property.

Summary: In this study, we isolated and characterized a pectic polysaccharide, WSMP-A2b, from Swertia mileensis. WSMP-A2b is mainly composed of RG-I, RG-II, and HG domains, with a mass ratio of 2.1:1.0:2.2. WSMP-A2b exhibited strong antioxidant activity, potentially attributed to its high galacturonic acid content. Moreover, WSMP-A2b showed protective effects against oxidative stress in INS-1 cells by reducing ROS production and increasing the GSH/GSSG ratio.

Summary: Astragalus membranaceus is a valuable medicinal plant species widely distributed in Asia with its root being the main medicinal tissue rich in methoxylated flavonoids. The chemical composition and antioxidant activity of the plant can be influenced by its origin, as shown through UHPLC-MS/MS analysis of extracts from four different origins. The study identified key compounds that can differentiate A. membranaceus from different regions and found that extracts from Inner Mongolia exhibited the highest antioxidant activity.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
