Abstract

The effect of some herbicides on the soybean oil quality and quantity has been studied. Herbicides caused a highly significant increase in soybean oil content. Statistical analysis showed that there was no and highly significant differences in acid value; unsaponifiables and saponification value and iodine value respectively of soybean oil extracted from plants subjected to various herbicides. The increase of herbicides application rates exhibited profound effects on the physical and chemical characters of soybean oil. The application of herbicides leads to the following changes on soybean oil fatty acids: decrease the concentrations of 13:0, 15:0, 18:0 and 20:0; increase the quantity of 16:0 and the appearance of 10:0, 11:0, UC15, 16:1 and 17:0 as new synthetically fatty acids. The total unsaturated to total saturated fatty acid ratios showed that cobex and linuron at low application rates caused desaturation some of 18:1 to form 18:2. On the contrary, these herbicides at high application rates exhibited the reverse effect.
