Residents commonly use it as tea. Preliminary experiments conducted by our research team revealed that the <i>Murraya tetramera</i> Huang polysaccharides (MTHPs) exhibit significant inhibitory effects on alpha-glucosidase (α-glucosidase) and alpha-amylase (α-amylase). In this study, MTHPs were purified using diethylaminoethyl cellulose-52 (DEAE-52) anion-exchange chromatography and Sephadex G-75 gel chromatography, resulting in a homogeneous polysaccharide named MTHP-2-a. Structural analysis indicates that MTHP-2-a has a weight-average molecular weight (Mw) of 62.25 kDa. It primarily consists of rhamnose (Rha), arabinose (Ara), galactose (Gal), and glucose (Glc). The backbone fragments include Araf-(1 ⟶, ⟶ 3)-Rhap-(1 ⟶, ⟶ 3)-Araf-(1 ⟶, ⟶ 5)-Araf-(1 ⟶, Glcp-(1 ⟶, ⟶ 2)-Araf-(1 ⟶, ⟶ 2,5)-Araf-(1 ⟶, Galp-(1 ⟶, ⟶ 4)-Galp-(1 ⟶, ⟶ 3)-Galp-(1 ⟶, ⟶ 6)-Glcp-(1 ⟶, ⟶ 6)-Galp-(1 ⟶, and ⟶ 3,6)-Galp-(1 ⟶. In vitro antidiabetic activity assays demonstrate that MTHP-2-a effectively inhibits α-amylase and α-glucosidase, with IC₅₀ values of 1.24 ± 0.02 and 0.32 ± 0.004 mg/mL, respectively. For comparison, the well-known antidiabetic drug acarbose exhibited similar inhibitory effects, with IC₅₀ values of 1.80 ± 0.06 mg/mL for α-amylase and 0.21 ± 0.006 mg/mL for α-glucosidase. These results suggest that MTHP-2-a exhibits comparable inhibitory potency to acarbose, a widely used antidiabetic agent. Furthermore, through both <i>in vitro</i> and in vivo experiments, MTHP-2-a can significantly exhibit hypoglycemic effects. The molecular structure and sugar composition of MTHP-2-a were purified and elucidated for the first time, revealing its strong potential for antihyperglycemic activity.

This study focused on the development and evaluation of a green cabbage-enriched meal and the investigation of the impact of the enriched cookies on selected proinflammatory cytokines and hormones in pre-eclamptic Wistar rats. A cabbage-based diet was formulated and assessed for proximate composition and sensory qualities. In vivo studies were carried out with thirty-five female rats, which were completely randomized into 7 groups. The effect of continued feeding with the diet on immunological parameters was observed. The data obtained from the results were subjected to statistical analysis using analysis of variance (ANOVA). The proximate composition results indicated that the cabbage-based diet exhibited the highest ash content (2.47%–3.6%) and fiber content (2.40%–4.03%). Additionally, the cabbage-based diet exhibited a lower fat content of 9.00%. However, the pre-eclampsia (PE) + cabbage diet group demonstrated TNF-α and IL-6 levels comparable to control groups, showing the anti-inflammatory potential of cabbage, likely due to its sulforaphane content. Similarly, the PE + amlodipine group exhibited reduced cytokine levels, reinforcing the anti-inflammatory effects of the antihypertensive drug. Hormonal analysis revealed significantly lower progesterone levels in pre-eclamptic rats, aligning with impaired placental function and increased vascular resistance. However, the cabbage-based diet appeared to mitigate these hormonal disruptions.

In sorghum, pressure rice cooking resulted in the highest total phenolic (110.90 mg GAE/g) and flavonoid (46.83 mg CE/g) contents, whereas both pressure rice cooking and steaming improved antioxidant activities across all assays. However, steaming was the most effective in NAFLD-related functionality, showing the most pronounced lipase inhibition (35.66%) and the greatest reduction in lipid accumulation in HepG2 cells (84.67%) under free fatty acid (FFA)–induced conditions. Although Italian millet showed lower baseline activity than sorghum, steaming consistently resulted in the highest phenolic content (ranging from 19.06 to 26.16 mg GAE/g), improved antioxidant activities, and enhanced lipase inhibition (from 8.00% to 9.70%) compared to all other treatments. Lipid accumulation inhibition was observed only in the steaming group, where lipid levels were reduced to 94.15% of those in the FFA-induced control. Thermal treatments led to functional improvements that were associated with increases in bioactive compounds, such as arginine, branched-chain amino acids, and sulfur-containing amino acids, which have been associated with the regulation of lipid metabolism and hepatic function.
