摘要
The essential oils isolated from basil (Ocimum sp.), chamomile (Chamomilla recutita L.), thyme (Thymus vulgaris L.) and oregano (Origanum sp.) were analysed rapidly and non-destructively applying different vibrational spectroscopic methods (ATR-IR, NIR and Raman spectroscopy). Whereas NIR spectroscopic data can be interpreted only by application of chemometric algorithms, IR and Raman spectra obtained from the essential oils present characteristic key bands which can be used as marker bands to discriminate different plant chemotypes. The methods described will be very useful in the flavour and fragrance industry to control very easily the purifying, blending, and redistilling processes of essential oils.
