Carbonyl compounds isolated from the buds (squares) of Deltapine Smoothleaf cotton by steam distillation, column chromatography, and Girard T procedure were identified by reaction gas chromatographic techniques, by thin layer chromatography of derivatives, and by ultraviolet and infrared spectroscopy. The 14 components identified of the 40 found present accounted for 88 % of the carbonyl fraction, which itself constitutes 1.4% of the square oil. A qualitative survey of the total oil composition is presented. Carbonyl compounds identified and their quantity (parts per million) in the oil were: acetone (98), isobutyraldehyde (14), butyraldehyde (56), isovaleraldehyde (70), hexanal (6900), heptanal (1050), trans-2-hexenal (2690), nonanal (252), 2-octenal (56), benzaldehyde (238), 2-nonenal (406), trans-2-cis-6-nonadienal (364), ptolualdehyde (28), and myrtenal (56).
