Background

Naringin dihydrochalcone is an artificial sweetener and flavonoid that has been isolated from various plants and has antioxidant activity.1,2 It scavenges ABTS , oxygen, and 2,2-diphenyl-1-picrylhydrazyl radicals in cell free assays (IC50s = 24, 322.8, and 318.9 μM, respectively).2

Protocol

Cell experiment:

HBZY-1 cells are plated into 96-well plates and pretreated with various concentrations(1, 5, 10, 25, 50, 100 μM) of naringin for 2 h. Then cells are treated with 30 mM glucose for 24 h. The control group is added sterile normal saline in the same volume. After treatment, all the wells are incubated with 20 μl of 5 mg/ml MTT for 4 h at 37°C. Subsequently, 100 μl of DMSO are used to dissolve the formed formazan crystals after removal of the supernatant. The result is recorded at 490 nm on a microplate reader[1].

Animal experiment:

Rats: The rats are randomly divided into six groups: control, naringin (80 mg/kg), STZ, STZ+naringin (20 mg/kg), STZ+naringin (40 mg/kg), STZ+naringin(80 mg/kg). The rats in the STZ and STZ+naringin groups are intraperitoneally injected with STZ (65 mg/kg). The control and naringin groups are intraperitoneally injected with 0.1 M citrate buffer of same volume. After injection of STZ for 3 and 5 days, blood glucose levels are measured by tail vein puncture blood sampling[1]. Mice: Sixty 4-week-old male mice are randomized into four groups and fed for 20 weeks with either control diet or high-fat diet chow. Mice are dosed with 100 mg/kg of naringin daily. Mice body weight and food intake are weekly measured. Following behavioral assessment, animals are deeply anesthetized with isoflurane and sacrificed by decapitation after fasting for at least 5 h. Their plasma is collected for further analysis[4].
