Naringin dosage

Naringin is a glycosylated flavanone naturally present in citrus fruits, particularly grapefruit (Citrus paradisi). It is responsible for their bitter taste and has widely studied antioxidant, lipid-lowering, and anti-inflammatory properties. Its measurement ensures the standardization of plant extracts and the conformity of nutraceutical formulations.

This analysis is crucial in the following contexts:

• Flavonoid content verification for quality control
• Evaluation of the bioactivity of citrus-based extracts
• Standardization of finished products (powders, capsules, functional drinks)

Analytical methods: HPLC-DAD or LC-MS

High-performance liquid chromatography (HPLC) with UV detection (DAD) is the reference method for naringin analysis. In some cases, LC-MS analysis may be preferred to increase sensitivity, particularly in complex or low-concentration matrices.

The analytical parameters (solvents, pH, temperature, wavelength) are adapted to the nature of the matrix being analyzed.

Affected matrices

This analysis applies to different types of products derived from citrus fruits or flavonoid plants:

• Dried citrus extracts or hydroalcoholic extracts
• Standardized vegetable powders
• Citrus-based food supplements
• Functional drinks enriched with flavonoids

Industrial applications

Naringin dosage is essential for industry players:

• Nutraceuticals: for the development of supplements targeting lipid metabolism, detoxification, or inflammation management
• Food industry: for formulating products based on grapefruit or bitter citrus fruits
• Research and development: within the framework of pharmacokinetic studies or innovative projects

Recommended Related Analyses

To complete the evaluation of your flavonoid extracts, we recommend:

• Naringenin assay – active aglycone metabolite derived from naringin
• Dosage of hesperidin – a complementary flavanone in citrus extracts
• Luteolin assay – a flavone often associated with plant complexes
