ABSTRACT
Volatile aroma compounds of simultaneous distillation and extraction (SDE) from black-currant (Ribes nigrum L.) leaves, buds, and berries were analysed by capillary gas chromatography with OV-101, PEG 20M, and CYDEX B stationary phases, and by gas chromatography--mass spectrometry. A total of 63 compounds were identified. The monoterpenes 3-carene (20--27%), (Z)-�-ocimene (2--11%), �-phellandrene (3--11%), and terpinolene (7--10%) and the sesquiterpenoids (E)-� -caryophyllene (5--9%) and caryophyllene oxide (0.5--10%) were identified in high quantities in blackcurrant oils. The oil yields from blackcurrant buds were 0.21%, from leaves 0.04%, and from berries up to 0.003%. Variation in the concentrations of the oil components during the ripening process was studied and the enantiomeric ratio of some monoterpenoids was determined.
