Hesperidin and naringin are flavonoids that are found in citrus fruits. Our aim was to create an model of Alzheimer's disease (AD) and to evaluate the neuroprotective effects of hesperidin and naringin in SK-N-AS and AD model cells. Aβ was used to create an AD model in SK-N-AS cells. The cytotoxicity of hesperidin and naringin was evaluated using MTT. β-amyloid, tau and α-synuclein distributions were analyzed using indirect immunoperoxidase staining to investigate the neuroprotective effects of hesperidin and naringin. The AD model was created by 1 µM of Aβ for 48 hours after ThT staining. The intensity of β-amyloid was reduced through both hesperidin and naringin treatment in AD model cells. Both flavonoids significantly decreased the intensity of α-synuclein in SK-N-AS and AD model cells. Hesperidin and naringin can be potentially used as neuroprotective agents. Naringin may be more effective than hesperidin in the accumulation of β-amyloid and tau proteins.

Flavonoids derived from plants in the citrus family can have an alleviating effect on allergic asthma. The aim of this study was to provide insights into the mechanisms by which these compounds exert their effects on allergic asthma by combining theoretical and practical approaches. Aurantii Fructus Immaturus flavonoids (AFIFs) were obtained by solvent extraction and were determined by high performance liquid chromatography (HPLC).

An α-l-Rhamnosidase gene with an open reading frame of 3192 bp encoding a 1036-amino acid protein (EhRha) was cloned from Emiliania huxleyi for flavonoid hydrolysis on the cell surface of Pichia pastoris (P. pastoris) strain GS115 by fusing with the anchor protein (AGα1) from Saccharomyces cerevisiae. Fluorescence microscopy and flow cytometry assays revealed that EhRha was successfully displayed on the cell surface of P.

The current study was conducted to explore the phytochemical composition and in vitro antioxidant activity of Moringa oleifera leaves aqueous extract (MOLE), as well as its in vivo modulatory effects on abamectin (ABM)-induced oxidative stress in rat erythrocytes and brain tissue. Following extraction, the total phenolic, flavonoid, condensed tannin and ortho-diphenolic contents of MOLE were determined. High-performance liquid chromatography (HPLC) analysis allowed the identification and the quantification of 12 bioactive compounds: gallic acid, chlorogenic acid, caffeic acid, vanillic acid, quercetin, ferulic acid, ascorbic acid, alizarin, hesperidin, neohesperidin, resveratrol, and naringin.

A promising approach for managing root caries is the use of cross-linking agents to stabilize collagen. However, despite testing various natural and synthetic agents in vitro, their efficacy remains uncertain. The aim of this review was to examine which cross-linking agent performs better in reducing root caries lesion depth and the release of hydroxyproline, which is a marker of collagen degradation.
