Abstract:
To study the effect of different storage time on the chemical compositions and sulfur dioxide residues of sulfur-fumigated Gastrodiae Rhizoma (GR), and provide scientific basis for solving the quality and safety issues of sulfur-fumigated traditional Chinese medicinal materials. GR, sulfur-fumigated GR and its medicinal slices were stored under the same conditions, and then 8 active ingredients and sulfur dioxide residues were measured respectively. The results showed that the content of gastrodins in sulfur-fumigated GR and its medicinal slices was significantly lower than that in the non-fumigated GR. Moreover, the content of sulfur dioxide residue in sulfur-fumigated GR was significantly higher than that in its medicinal slices. That is to say, sulfur fumigation degree had significantly higher effect on GR quality as compared with its medicinal slices. During the whole storage time (8 months), the content of the eight chemical components in GR was not changed greatly in general. However, after the storage for 4 months, the content of 8 components and sulfur dioxide residues in all of GR samples were significantly changed. In particular, the content of sulfur dioxide residue in GR medicinal materials decreased up to 50% or more.
