Article Abstract
Objectives: is an ethnomedicinal plant used by the people of the North East Region of India to manage various health issues including diabetes and rheumatism. The present study examines the total phenolic and flavonoid content, pharmacological evaluation of the plant extract/fractions, and phytochemical characterization using HRLC-MS.
Methods: Ethanol extract of leaves (PJEE) and its fractions were estimated for total phenolic and flavonoid content following the Folin-Ciocalteu and aluminium chloride method. DPPH (2,2-diphenyl-1-picrylhydrazyl) and NO (nitric oxide) scavenging methods were utilized for evaluating antioxidant properties; albumin denaturation and proteinase inhibitory assay methods for assessing antiinflammatory potential. Additionally, extract/fractions were evaluated for their antidiabetic potential using α-glucosidase and α-amylase inhibition assays. HRLC-MS was employed for phytochemical profiling of the ethyl acetate fraction (PJEAF).
Results: PJEAF contains the highest total phenolic (48.3 ± 0.64 mg GAE/g) and total flavonoid (22.6 ± 0.09 mg QE/g) content. PJEAF scavenges DPPH radical (IC = 29.1 ± 0.25 µg/mL) and NO radical (IC = 46.6 ± 0.20 µg/mL) potently. PJEAF also exhibited potent antiinflammatory potential with IC of 220.8 ± 1.33 and 231.5 ± 1.25 µg/mL against albumin denaturation and protease inhibition assay, respectively. PJEAF had potent inhibition of α-amylase and α-glucosidase enzymes, with IC values of 205.9 ± 1.12 and 132.2 ± 0.65 µg/mL, respectively. The HRLC-MS profiling of PJEAF indicated the presence of forty-three phytoconstituents, including 2'-Apo-beta-carotenal, Sinensetin, Kaempferol-3-o-(6"-malonyl-glucoside), Heliannone B, Rhoifolin, Quercetin-3-o-rutinoside.
Conclusion: These findings indicated that possesses significant antioxidant, antiinflammatory, and antidiabetic potential, and presence of possible metabolites also makes the plant an important source of drug development and therapeutic applications.

Background: This study aimed to develop gluten-free bread from chickpea flour by incorporation of varying levels (0 (B-C), 2.5 (B-1), 5 (B-2), and 10 g kg (B-3)) of madımak leaf powder (MLP), and to investigate its effect on physicochemical and bioactive properties, glycemic index, texture, and sensory attributes.
Results: Moisture ranged from 229 (B-3) to 244 g kg (control), while ash content increased with MLP, reaching 47 g kg in B-3 compared to 15.

Background: Secondary fermentation can reduce variability in cocoa bean quality caused by the spontaneous, uncontrolled nature of primary fermentation. However, its optimization remains unexplored. This study evaluated the improvement of secondary fermentation through the combined use of Citrus limon peel and inoculation with Candida tropicalis H1Y4-1 as a starter.
