摘　　要：研究了西兰花花球生长发育过程中的抗氧化活性和主要营养功能成分的变化,为西兰花合理生产和消费提供参考。结果表明,西兰花花球在生长过程中抗氧化活性及营养功能成分不断增加。商业采收期时,西兰花中几种成分含量的高低顺序是花青素、多酚、类黄酮、Vc、叶绿素a和b、类胡萝卜素。在花球发育过程中,类胡萝卜素和花青素含量分别增加11.9倍和10.9倍,其次是叶绿素含量增加6倍左右。其他成分增加幅度较小,Vc、类黄酮、可溶性固形物分别增加2.44倍、1.44倍、1.54倍,总酚含量增加不大。The antioxidant activity and nutritional components of broccoli during growing periods were determined, which will supply reference for proper production and consumption of broccoli. The results showed that antioxidant activity and content of relative nutri- tional components increased during the floret growth of broccoli. The content of compounds orderly was anthocyanin, total polyphe- nols ,flavonoid, vitamin C, chlorophyll. During the growth of fioret, carotenoid and anthoeyanin increased to 11.9 and 10.9 times, and chlorophyll increased to 6 times. The increase rate of other components was smaller. Vc, flavonoid, soluble solid content （SSC） in- creased to 2.44,1.44,1.54 times, while total polyphenols didn＇t change significantly.
