UV Second Derivative Spectrophotometric Determination of Synthetic Decanoyl Acetaldehyde in Compounded Chinese Medicinal Prescriptions / 中草药

ABSTRACT

UV second derivative spectrophotometry was used for the analysis of compounded Chinese medicinal prescription in order to eliminate interference from prescription base. Amplitude D and △A were taken as the quantitative informatious. Synthetic decanoyl acetaldehyde in compounded Chinese medicinal prescription were determined by two methods. The Correlation coefficicnts of the standard curve were found to be 0.9994 and 0.9996,the mean recovery to be 98.10% and 96 31%.
