【摘要】 研究了水稻种子在不同的发芽条件下维生素C、B₁、B₂、E,谷胱甘肽,β-胡萝卜素等活性物质含量的变化。结果表明:维生素C、谷胱甘肽、维生素B₂的含量随着发芽时间的延长而呈线性增加,在发芽的48h内,维生素B₁的含量是增加的,而后逐渐降低,维生素E的含量逐渐增加至第三天时达到最大值,以后略有下降;样品中未检测出β-胡萝卜素;光照、醋酸钠、葡萄糖可显著提高维生素C的含量,其中醋酸钠的效果最佳;硫酸钠提高谷胱甘肽含量的效果极好。更多还原

【Abstract】 The changes of active components such as ascorbic acid, thiamine, riboflavin, tocopherol and glutathione during germination of rice seed were studied in this paper. The results are shown as follows; The increases in contents of ascorbic acid,glutathione and riboflavin took place linearly with germinating time (Thiamine content increased within the first 48 hrs and thereafter reduced gradually: Tocopherol content in rice reached a peak value on the third day during germination, then decreased slightly ;β-carotene was not found in germinated rice ;Light, aqueous CH3COONa, aqueous glucose etc. as mediums or factors could promote the content of ascorbic acid and aqueous CH3COONa had the most obvious effect on promoting ascorbic acid content; Aqueous Na2SO4 was very effective to promote the content of glutathione.更多还原
