Descrição

Descrição geral

Citral usually is a key component of lemon scented essential oils[1] and also in volatile oils of plants like ginger[2], which can exist like a mixture of two isomers, cis-isomer neral and trans-isomer geranial.[2] It can serve as potential candidate used in the treatment of tumours.[2] It can mainly find applications as a food additive and as a fragrance in cosmetics.[1]

Citral, a volatile compound, is considered as an important raw material for lemon scented tea tree oil[3][4] and Cymbopogon citratus volatile oil.[5] It is used as an aroma ingredient in food products, aromatherapy,[6] cosmetic industry, scenting of soaps and toiletries.[3][4] The antimicrobial activity of this compound on the airborne microbes is investigated.[4]

Aplicação

Citral may be used as an analytical reference standard for the quantification of the analyte in:

• Essential oils using reversed-phase high performance liquid chromatography with photodiode array detection (RP-HPLC-PDA), further confirmed by gas-chromatography coupled to mass spectrometry (GC-MS).[6]
• Cymbopogon citratus volatile oil using high performance liquid chromatography with UV detection (HPLC-UV) and gas chromatography coupled to mass spectrometry (GC-MS).[5]
