Carrot seed essential oil is commonly utilized in cosmetics, perfumes, and various food products as a fragrance and flavoring agent. It is sourced from specialized glandular structures called vittae within the plant. Chemical analyses have revealed that carrots contain various range of compounds like polyphenols, glycosides, alkaloids, saponins, sesquiterpenes, and essential oils. Researchers have extensively investigated the chemical constitution of carrot seed essential oil obtained through hydro-distillation, noting variations in composition across different plant parts. This essential oil exhibits diverse biological activities including antimicrobial, antibacterial, antifungal, herbicidal, antioxidant, and anticancer properties. Its health benefits are attributed to its antiseptic, disinfectant, detoxifying, antioxidant, anticarcinogenic, tonic, carminative, depurative, diuretic, and stomachic properties. This review comprehensively discusses the morphological characteristics of carrot plants, their essential oil constituents, chemical compositions, and biological functionalities.
