Area of Science:

• Analytical Chemistry
• Pharmaceutical Sciences
• Lipidomics

Background:

• Liposomes are crucial lipid-based drug delivery systems.
• Accurate characterization of liposome composition is essential for quality control.
• Existing methods for lipid analysis can be time-consuming or require large sample volumes.

Purpose of the Study:

• To develop a rapid and sensitive analytical method for the simultaneous determination of all lipid ingredients in liposome formulations.
• To enable precise quantification of the drug-to-lipid molar ratio.
• To provide a versatile tool for quality control throughout the liposome preparation process.

Main Methods:

• Thin Layer Chromatography coupled with Flame Ionization Detection (TLC/FID).
• Chromatographic separation of liposomal ingredients on silica gel-coated quartz rods.
• Detection of separated lipids via hydrogen flame ionization and signal conversion to a chromatogram.

Main Results:

• Successful simultaneous determination of multiple lipid ingredients in a single analysis.
• High sensitivity allowing for the use of minimal sample quantities.
• Generation of reproducible chromatograms for accurate quantification.

Conclusions:

• The developed TLC/FID method offers an efficient and accurate approach for liposome characterization.
• This methodology can be applied at various stages of liposome preparation, from raw material inspection to final product analysis.
• The technique enhances quality control and aids in troubleshooting liposome formulation processes.
