[Re-study on characteristic fingerprint of volatile oil from Herba Pogostemonis by GC].
OBJECTIVE
To establish the characteristic fingerprint and parameter of volatile oil from Herba Pogostemonis.


METHODS
The dffferent collecting time and county samples of Herba Pogostemonis were determined by GC.


RESULTS
Accuracy, stability and repeatability of the method were good. The same region samples had good stability and main constituents were same in different collection time, but content were different. The samples collected from different region were more different in constituents and content.


CONCLUSIONS
The 11 components in common buildup the characterisitic fingerprint of volatile oil from Herba Pogostemonis. The ratiio of pogostone to patchoulic alcohol were used index parameter for quality evaluation and characteristics of producing region.
