【摘要】 目的:改进光黄素荧光法测定尿中核黄素的含量。方法:参考日本卫生试验法食品中核黄素的测定方法,利用核黄素分解为光黄素这一反应,以光黄素荧光法定量测定尿中核黄素含量。结果及结论:改进方法简便、快速,相对标准偏差1．11％-9．51％,加标回收率92．8％-100％,准确度及精密度均能满足分析要求。更多还原

【Abstract】 Objective: Lumiflavin fluorescence method was developed to detect the content of riboflavin in urine. Methods: Based on decomposition of riboflavin into lumiflavin, fluorescence method was used to determine riboflavin in urine. Results and conclusion: This method is simple, fast, accurate and the relative SD was from 1.11% to 9.51%, and the recovery was from 92.8% to 100%.更多还原
