Description

General description

Citral is a mixture of neral (cis isomer of 3,7-dimethyl-2,6-octadienal) and geranial (trans isomer of 3,7-dimethyl-2,6-octadienal). It exhibits antimicrobial activity and pheromonal effects and is generally used for the synthesis of vitamin A and ionones.

Citral is a monoterpene aldehyde used as an aromatic ingredient in food and cosmetic industry.

Application

• Citral has been used as an anti-tumor agent against breast cancer cell lines (MCF-7 and MDA-MB-231).
• It shows antipyretic effects which can be studied by systemic administration of lipopolysaccharide (LPS) to rats.
• It can undergo 1,3-dipolar cycloaddition reaction with trimethylsilylazide to form 1,2,3-triazolines which possess pharmaceutical properties.
