The aim of this study was to investigate the protective effects and mechanisms of hesperidin, a plant based active flavanone found in citrus fruits, under the oxidative stress and apoptosis induced by high levels of glucose in retinal ganglial cells (RGCs). RGC-5 cells were pretreated with hesperidin (12.5, 25, or 50 μmol/L) for 6 h followed by exposure to high (33.3 mmol/L) d-glucose for 48 h....

diosmin and hesperidin are natural flavonoid glycosides found in various plant materials, mainly in citrus fruits in different concentrations. diosmin for pharmaceutical use is obtained mainly semi-synthetically from hesperidin. hesperidin often accompanies diosmin as a natural impurity in different pharmaceutical formulations; therefore, a simple, fast and precise method for the simultaneous a...

Diosmin, hesperidin and naringin are flavonoid glycosides that occur naturally in citrus fruits. They exert a variety of pharmacological properties such as anti-inflammatory, antioxidant and free radical scavenging and antiulcer effects and also inhibit selected cytochrome P-450 enzymes resulting in drug interactions. A reversed-phase high-performance liquid chromatographic method has been deve...

Stroke is the third leading cause of death and disability around the globe. The aim of the present investigation was to evaluate the protective effect of hesperidin and its nitric oxide mechanism against cerebral ischemia reperfusion injury. Bilateral common carotid artery occlusion for 30 min followed by 24 h reperfusion was given to induce ischemia in rats. Animals were pretreated with hesper...

OBJECTIVE To develop a simple, selective, sensitive and accurate high-performance thin layer chromatography (HPTLC) method to determine the quantity of hesperidin in different varieties of citrus fruits. METHODS The method was carried out in aluminum-backed silica gel 60 F254 plates with ethyl acetate-methanol-water 15:3:2 (%, v/v) as mobile phase. RESULTS A compact band was obtained for he...

In the course of our screening work for new types of lipase inhibitors, hesperidin was identified as a simple and small molecular weight inhibitor in the peels of Citrus unshiu. Hesperidin inhibited lipase activity from porcine pancreas and that from Pseudomonas, and their IC50 was 32 and 132 micrograms/ml, respectively. Hesperidin, neohesperidin, narirutin, and naringin are known as the main f...

Neuropathic pain is caused by a primary lesion, dysfunction, or transitory perturbation in the peripheral or central nervous system. In this study, we investigated the hesperidin antihyperalgesic effects alone or combined with diosmin in a model of neuropathic pain to corroborate a possible synergistic antinociceptive activity. Mechanical and thermal hyperalgesia were assessed in the aesthesiom...

We investigated the effects of orange juice (OJ) or hesperidin, a component of OJ, on the pharmacokinetics of pravastatin (PRV) and the expression of both protein and mRNA of multidrug resistance-associated protein 2 (Mrp2) in the rat small intestine and liver. Eight-week-old male Sprague-Dawley rats were used in this study. OJ or a 0.079% hesperidin suspension was administered orally for 2 day...

Diabetic retinopathy is a complex disease that potentially involves increased production of advanced glycosylation end products (AGEs) and elevated aldose reductase (AR) activity, which are related with oxidative stress and inflammation. The aim of this study was to investigate the effects of hesperidin on retinal and plasma abnormalities in streptozotocin-induced diabetic rats. Hesperidin (100...

Accumulation of mast cells can be causally related to several allergic inflammations. Stem cell factor (SCF) as a mast cell chemotaxin induces mast cell migration. To clarify a new effect of Pyeongwee-San extract (KMP6, a drug for indigestion) for the treatment of allergy, we investigated the effects of KMP6 on SCF-induced migration of rat peritoneal mast cells (RPMCs). A molecular docking simu...
