Article Abstract
This study focused on the quality control (QC) of roots of Pall. from Hebei An-Guo Medicine Market, China. Plant roots were extracted using 70% aqueous ethanol with soxhlation and sonication extraction technologies. The extracts were then condensed, dried, and solubilised in methanol, ethanol, and water for chemical analysis. The sonication extract yielded higher amounts of total phenolics (33.12 mg/gDW) and flavonoids (17.59 mg/gDW) in ethanol compared to water and methanol. HPLC analysis showed a high concentration of gentiopicroside (588.48 μg/mL) in the ethanol fraction of the sonication extract, with loganic acid (283.58 μg/mL) and sweroside (9.49 μg/mL) in the water fraction. The soxhlation extract had lower concentrations of these compounds. The root extract (sonication extraction) of Pall. demonstrated dose-dependent antioxidant (DPPH, NBTs, FRAP) and outstanding antibacterial activities against and at lower concentrations.

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.
