Curcumin in plasma and urine: quantitation by high-performance liquid chromatography
Curcumin, a derivative of the plant Curcuma longa, is used extensively in the food industry. It is a major component of curry powder, and research has shown that curcumin may prevent cancer and other chronic diseases. We have developed a robust automated analytical method for the determination of curcumin in plasma and urine. The method involves extracting the curcumin from 0.2 ml sample volume with ethyl acetate /methanol organic solvents, and use of an internal standard, b-17-estradiol acetate. Analysis utilizes a reversed-phase C column and UV detection at 262 nm. Performance 18 characteristics have been assessed. The assay is linear from 0.2 to 7.0 mg/ ml.
The coefficient of variation for intra- and inter-day assays is <7.5%.
The average recovery of curcumin from plasma and urine is greater than 96%. The data presented in this report demonstrate that the method provides rapid, sensitive, precise and accurate measurements of curcumin concentrations in plasma and urine.

inter-day 天與天之間 即不同一天進行測試 例如星期一做完後另一天如星期四再進行測試
