When seeds of soybean were subjected to accelerated aging, the amount of total lipid which was extracted from the whole seed increased with "age," whereas the extractable phospholipid decreased slightly. This small decline primarily reflected changes in the amounts of phosphatidylcholine and phosphatidylethanolamine. The levels of unsaturated fatty acids in the whole seed and in the seed axis showed no decline during aging. Similarly, the fatty acids in a polar lipid extract from the whole seed showed little change in unsaturation. These results suggest that oxidation of seed lipids may be unrelated to the process of seed aging.
当大豆种子进行加速老化处理时,从整粒种子中提取的总脂质含量随“老化程度”增加,而可提取的磷脂略有下降。这种小幅下降主要反映了磷脂酰胆碱和磷脂酰乙醇胺含量的变化。老化过程中,整粒种子和种子胚轴中的不饱和脂肪酸水平没有下降。同样,从整粒种子中提取的极性脂质提取物中的脂肪酸不饱和度变化很小。这些结果表明,种子脂质的氧化可能与种子老化过程无关。
