- Abstract
A new fluorescence spectrophotometer method was established for the determination of capsaieinoid in samples of purificated capsaicinoid or unpurificated capsaicinoid. Under Ex = 278 nm and Em = 312 nm, the linear equation of the flouresence intensity (I) and the concentration (c) of capsaicinoid was c = 1. 0377 x 10-3 I - 0.3667 and correlation coefficient was R = 0.9994 in 0.58 ∼ 5.8 µg/mL for capsaicin. The RSD was 0.0798% ( n = 5 ). The average recovery was 95.39 %.
