Carotenoid Extraction from Plant Tissues.

Area of Science:

• Phytochemistry
• Analytical Chemistry

Background:

• Carotenoids are natural pigments found in plants, offering diverse health benefits like antioxidant and anti-aging properties.
• They are classified into carotenes and xanthophylls and are utilized across food, pharmaceutical, nutraceutical, and cosmetic industries.
• Carotenoids play roles in photoprotection, photosynthesis, and act as precursors for plant hormones.

Purpose of the Study:

• To introduce carotenoids and detail a method for their extraction from plant tissues.
• To provide a comprehensive protocol for carotenoid extraction and analysis.

Main Methods:

• Extraction of carotenoids using chloroform and dichloromethane solvents.
• Analysis via reverse-phase High-Performance Liquid Chromatography (HPLC) using C30 columns.
• Gradient elution is employed for optimal separation.

Main Results:

• The protocol provides a complete pipeline for carotenoid extraction from plant sources.
• C30 columns are recommended over C18 columns for their superior selectivity with isomers and hydrophobic compounds.

Conclusions:

• The described method offers an effective approach for carotenoid extraction and analysis.
• This protocol facilitates further research and application of carotenoids in various industries.
