[A research on the constituents of ginger in various preparations].

The constituents extracted by ether from ginger in different preparations were checked up by GC-MS-DS. The results are as follows: 25 constituents were found in fresh ginger; 22 in dry ginger, of which one had not been found in other forms of ginger; 23 in ginger roasted with sand in a pan, of which two had not been found in other forms of ginger; 23 in ginger charcoal, of which three had not been found in other forms of ginger. A comparison has been made of the content of the constituents in the ginger studied, and the result shows that some of the constituents have changed. All of the essential oil constituents in roasted ginger and ginger charcoal were reported for the first time.
