摘　　要：将金纳米粒子溶液直接滴加在中药饮片的表面,利用表面增强拉曼散射(SERS)可直接对硫磺熏蒸导致的Na2SO3残留进行检测,并对检测条件进行了优化。使用本法对硫磺熏蒸和无硫磺熏蒸的10组中药饮片分别进行测定,结果均具有显著差异。The sulfur-fumigated process was widely used during TCM process, which was demonstrated to possess destructive effect to inherent quality of Chinese medica, and bring damage to patients. A new surface-enhanced Raman scattering （SERS） method was developed for direct detection of residuary sodium sulfite in TCM decoction pieces only by dropping solution of gold particles onto sample surfaces. With no pretreatment process in this simple method, the method is extremely suitable for on-site rapid detection. 10 groups of TCM decoction pieces including sulfur fumigated and non-sulfur fumigated ones were detected, and dramatic differences were obtained.
