摘要
目的:考察唾液与血浆中核黄素药时曲线的相关性。方法:成人口服核黄素片后,用荧光分光光度法测定唾液中的核黄素,其激发波长为475.4nm,发射波长为524.7nm。结果:核黄素的回收率可达96%,其线性范围为5ng·ml-1~3μg·ml-1,检出限量为5ng·ml-1,回归方程为△F′=0.116c+0.232,r=0.9999。结论:测得唾液中核黄素药时曲线与文献报道的血浆药时曲线形状相似。
OBJECTIVE:To observe the correlation of concentration time curves of riboflavin in salive and plasma.METHOD: After peple orally taking riboflavin tablets,the riboflavin in salive was determinated by fluorescence spectrophotometry with excitation wavelength 475.4nm and emission wavelength 524.7nm.RESULTS:The recovery of riboflavin was over 96%.The detection limits of riboflavin was 5ng·ml -1 ,and the calibration curve was linear in the range of 5ng·ml -1 ~3μg·ml -1 .The regression equation was △F′ =0.116c+0.232( r =0.9999).CONCLUSION:The concentration time curves of riboflavin in salive was similar to these in plasma.
