Analysis of Coenzyme Q10

Význam tématu

Coenzyme Q10 plays a crucial role as an antioxidant in cellular energy production and is widely included in dietary supplements. Accurate determination of its content is essential for quality control and regulatory compliance in food science.

Cíle a přehled studie / článku

The objective was to establish a robust reversed-phase HPLC-UV method using Shim-pack FC-ODS column for the quantitative analysis of CoQ10 in dietary formulations. The study outlines chromatographic conditions and demonstrates method suitability for routine laboratory use.

Použitá metodika a instrumentace

Chromatographic parameters:

• Column: Shim-pack FC-ODS (75 mm x 4.6 mm I.D., 3 μm)
• Mobile phase: Methanol/ethanol (13/7, v/v)
• Flow rate: 1.5 mL/min
• Column temperature: 40 °C
• Injection volume: 5 μL
• Detection: UV-VIS at 275 nm, cell temperature 40 °C

Shimadzu HPLC system and Shim-pack series column were employed to achieve stable retention and peak shape.
