ABSTRACT
Objective:
To establish the GC-MS fingerprints of volatile oil in crude, water-processed, and vinegar-processed Cyperi Rhizoma, and to capture the whole scope of the chemical constituents changing.Methods:
The fingerprints of volatile oil in crude, water-processed, and vinegar-processed Cyperi Rhizoma were established by GC-MS. And the data were analyzed by chromatographic fingerprint similarity evaluation software for Chinese materia medica (Version A).Results:
The similarities of each group were good, which indicated that the technology was stable and feasible. The crude group gained 52 common peaks, 28 as the water-processed group, and 53 as the vinegar-processed group. Meanwhile, 46 chemical components among the peaks above were identified in total. Comparing with the three groups, the kinds and contents of many components in each group were changed after processing. With the crude group as reference, the differences between the water-processed group and vinegar-processed group were contrastively analyzed before and after processing, and the Cyperi Rhizoma processed with vinegar could remain the chemical constitutions in its volatile oil better.Conclusion:
Using vinegar as processing accessory is scientific and reasonable. Vinegar could play a role in protecting the compounds of volatile oil in Cyperi Rhizoma steadily.
