| Abstract: | ve: To establish a method for rapid determining phenobarbitone in human plasma. Methods: Using RP -HPLC with carbamazepine as standard, to determine concentration of phenobarbitone in human plasma. The separation wasperformed on shimadzu shimpack CLC - C18 column with methanol-water(60: 40)as mobile phase. The flow rate was 0. 8ml/min. The wavelength for measurement was 254nm. Results: The linear ranges of phenobarbitone was between 5 - 40 ug. ml-1 with r =0. 9999, The lowest limit of detection was 11. 57ng/ml, The average recoveries for phenobarbitone in three different concentration were 100. 24% , 100. 28% , 99. 41% , with RSD of 0. 7% , 2. 7% and 5. 89% respectively (n = 9). The RSD values of intraday and interday were 3. 3%, 5. 2% 8. 7% and 7. 3%, 7. 3%, 9. 2% (n=9). Conclution: This method is accurate, rapid and ease, with high sensitive and good repeatability. It can be used routine method by TDM. |
