The purpose of the present study was to investigate the possible presence of furfurals in chlorhexidine-discolored pellicle. Pellicle material was scraped off teeth and hydrolyzed in sulfuric acid and the hydrolysate then extracted with ether and examined by thin layer chromatography and gas chromatography-mass spectrometry. The presence of furaldehyde in discolored pellicle was demonstrated by these methods. There were also indications of hydroxymethyl furfuraldehyde in the thin layer chromatograms.
本研究的目的是调查洗必泰致变色的薄膜中可能存在的糠醛。从牙齿上刮下薄膜材料,在硫酸中水解,然后用乙醚萃取水解产物,并通过薄层色谱法和气相色谱 - 质谱法进行检测。通过这些方法证实了变色薄膜中存在糠醛。在薄层色谱图中也有羟甲基糠醛的迹象。
