主 题：Titration-fluorescence spectrometry Chinese Pharmacopoeia Sulfur dioxide Chinese medicinal materials Residue
摘 要：With sulphur-fumigated Chinese medicinal materials （Fritillaria thunbergii , Isatis #utigotica , Asparagus cochinchinensis and Poria cocos ） as the test materials, sulfur dioxide or sulfite residue was determined by the method in Chinese Pharmacopoeia （2015 edition） and titration-fluorescence spectrometry, respec- tively. The results showed that there were significant differences in measured value between titration-fluorescence spectrometry and phmmacopoeia method. The t result of titration-fluorescence spectrometry was much closer to the actual content of sulfur dioxide in Chinese medicinal materials. Thus, titration-fluo- rescence spectrometry had higher application value
