[Study on yield and quality of Scutellaria baicalensis from different habitats].
OBJECTIVE
To compare the economical characters, yield characters and major effective ingredient content of Scutellaria baicalensis from different habitats.


METHODS
The characters were studied by field randomized block test combining analysis of variance, correlation analysis and quality analysis.


RESULTS
There are significant differences in yield and quality of the crude drugs from different habitats.


CONCLUSIONS
The crude drug from Pingyi (Shandong province) is better than those from other habitats.
