【Abstract】 Twenty healthy elderly males aged 60~70, having lived in Changsha over 10 years, were divided into 3 groups according to the riboflavin (VB2) content in daily diet (0.5mg 0.6mg 0.8mg). Additional complement of VB2 tablets administered orally increased the total amount of VB2 to 1.0mg 1.5mg 2.0mg respectively. The procedure was carried out for a period of 15 days. Urine of fasting for 1 hour and of giving 5mg VB2 orally for 4 hours were analysed by micro-fluorimetric method right before and after the experimental period. The data were collected and managed statistically. It is inferred that daily saturation requirement of VB2 for the elderly is 2.0mg and daily requirement is somewhat lower than l.5mg.更多还原
