| Abstract: | Two methods for the rapid determination of 10-HDA in royal jelly with the def-frential spectrophotometry and the first derivative spectrophotometry are presented. The maximum absorbance of the diffrential spectrophotometry is at 228. 0 nm. The determination wavelengths of the first derivative spectrophotometry are ( + )204. 5 and (-)233. 5 nm. The linear ranges are 0-20 ng/ml (diffrential spectrophotometry) and 0-15 fig/ml (first derivative spectrophotometry), respectively. Both methods are simple, rapid and accurate in actual determination. |
