Opis

Opis ogólny

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

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

Zastosowanie

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).
• Cymbopogon citratus volatile oil using high performance liquid chromatography with UV detection (HPLC-UV) and gas chromatography coupled to mass spectrometry (GC-MS).
