[Investigation on quality difference between Cordyceps of Sichuan and those of Xizang].
OBJECTIVE
The quality difference among the Cordyceps specimens which grew in various micro-ecological environment and between those from Kangding of sichuan and those from Naqu of Xizang was compared and analyzed.


METHODS
The specimens from various spots in field were collected, their appearance properties were analyzed, content of adenosine was assayed, and their difference on ecological hereditary variation was discussed.


RESULTS
The biggest values of quality difference among the Cordyceps specimens from various micro-ecological environment can surpass that between specimen of Sichuan and specimen of Xizang.


CONCLUSIONS
The effect of the micro-ecological environment on the quality of the Cordyceps might exceed that of extensive climates and region differences at times.
