The changes in cottonseed constituents at different boll ages ranging from 5 to 60 days after flowering are reported. A gradual depletion of sugars coincided with gradual formation of oil has been found. Proteins are accumulated at a more or less even rate. Gossypol starts its appearance in 10 days old boll, and continuously increases. The iodine value of the oils shows gradual increase, while the acid value continuously decreases. Continuous decrease in total saturated fatty acids during development and maturity was observed while linoleic acid continuously increases. The total phospholipid content of the oil continuously decreases. The total saturated fatty acid contents of the phospholipids are generally higher than that of their corresponding oils.
本文报道了开花后5至60天不同棉铃龄期棉籽成分的变化。研究发现，糖分的逐渐消耗与油脂的逐渐形成同时发生。蛋白质以大致均匀的速率积累。棉酚在棉铃10日龄时开始出现，并持续增加。油脂的碘值呈逐渐上升趋势，而酸值持续下降。在发育和成熟过程中，总饱和脂肪酸持续减少，而亚油酸持续增加。油脂中总磷脂含量持续下降。磷脂中总饱和脂肪酸含量通常高于其相应油脂中的含量。
