Establishment of Rapid Detection Method for Sulfur Dioxide Residues in Chinese Herbal Medicines
Objective: To establish a fast detection method of sulfur dioxide residues in stoved traditional Chinese medicine(TCM). Method: Colour chromaticity was detected by spectrocolorimeter
taking advantage of the principle of purple substance creation by sodium sulfite reacting with OPA and ammonium acetate under certain conditions
20 batches of TCM were detected
and their sulfur dioxide residues were semi-quantitative. Result: A linear relationship was obtained between color chromaticity and the addition of sodium sulfite in the range of 0-25.23 μg
the range of sulfur dioxide residues in samples could be determined by comparing with the standard addition of sodium sulfite. Conclusion: This method was simple
rapid and sensitive
it could provide a reference for fast detection and half quantification of sulfur dioxide residues in TCM.
