摘要:

应用HPLC 方法对7 个四川小麦品种(系)幼苗中抗氧化组分阿魏酸含量进行测定,以探讨小麦苗中阿魏酸含量的变化规律,确定加工麦苗粉的最佳采收时期。结果表明,7 个小麦品种在生长1~4 周时阿魏酸平均含量分别为0.2575、0.2865、0.3364、0.5193mg/g。阿魏酸的含量随着小麦的生长周期均呈增长趋势,在第3~4 周每个品种阿魏酸含量增加明显。方差分析表明,在α =0.01 水平上,其含量增长存在极显著差异,且品种间的含量和增幅有差异。偏相关分析表明,株高、干质量与阿魏酸的含量的偏相关系数均未达显著水平,揭示在确定小麦苗收割时期时可以不考虑株高、干质量的影响。因此在加工生产麦苗粉时,若以阿魏酸作为该保健产品的有效成分指标,麦苗生长至第4 周采收最佳。

Abstract:

In order to explore the change trend of ferulic acid (FA) and identify the suitable harvest period of wheat seedling, the contents of ferulic acid in wheat seedling from 7 cultivation variants were determined by HPLC method. Results indicated that the average contents of ferulic acid from 7 cultivation variants in the first through the fourth weeks were 0.2575, 0.2865, 0.3364 mg/g and 0.5193 mg/g, respectively. An increase trend of FA content was observed and an obvious increase of FA content in each variant was exhibited from the third to the fourth week. A significant increase was confirmed by variance analysis. No obvious significant level was observed in partial regression coefficients among plant height and FA content or net weight. In addition, the best harvest season for wheat seedling was not affected by plant height and dry weight. Therefore, the optimal harvest time of wheat seedling was the 4th week of growth based on ferulic acid as an efficient component index.
