Abstract/Description: | Plant seed oils, including soybean seed oil,represent the major source of naturally derived toco-pherols, the antioxidant molecules that act as freeradical quenchers preventing lipid peroxidation inbiological systems and vegetable oil products. All fourisomers of tocopherols, i.e.a,b,c,dtocopherols thatexist in nature are found in soybean seeds. The bio-logical activity and the contribution of these isomers inimproving the oxidative stability of vegetable oil are inreverse order. Because of the nutritive value and theimportance for oil stability, enhancement of tocopherolcontent, through breeding programs, in soybean seedshas become a new and an important objective. Geno-typic variability, which is the basis of every breedingprogram, is scarcely reported for tocopherol contentand profile in soybean seeds. In the present investiga-tion, the tocopherol content and profile in seed samplesof 66 genotypes of Indian soybean were determined.The ratios observed between the lowest and the highestvalues fora,b,c,d, total tocopherol content were1:13.6, 1:10.4, 1:7.5, 1:9.1, 1:7.9, respectively. The meancontents fora,b,c,dand total tocopherols were 269,40, 855, 241 and 1,405lg/g of oil, respectively. Totaltocopherol content was the highest in ‘Co Soya2’ fol-lowed by ‘Ankur’. Concentration ofa-tocopherol wasthe highest (27%) in ‘Ankur’ followed by ‘MACS124’ (26%) whereas gamma tocopherol concentration wasthe highest (69%) in ‘VLS1’ and ‘PK327’ followed by‘MACS13’ (67%). In view of the fact that levels ofunsaturated fatty acids, apart from tocopherols, alsodetermine the oxidative stability of vegetable oils, therelationship of four isomers of tocopherols with eachother as well as with different unsaturated fatty acidsand oil content was also investigated in the presentstudy. All the four isomers of tocopherols exhibitedhighlysignificantcorrelationswitheachother(p< 0.001) whereasc-tocopherol and total tocopherolcontent showed a significant relationship with linoleicacid (p< 0.05). |
