[Study on the content of imperatorin and HPLC fingerprint of Baizhi collected from different areas].
OBJECTIVE
To compare the content of imperatorin and HPLC fingerprint of Baizhi collected from different areas.


METHODS
The medicinal materials and seeds of Baizhi from 15 main habitats of 7 provinces and cities were collected, and the seeds were planted in the germplasm resource garden of Suining, Sichuan. The content of imperatorin and HPLC fingerprint were compared using the samples collected from different areas and germplasm resource garden collected and dried at the most suitable harvest date.


RESULTS
The differences on the content of imperatorin and HPLC fingerprint were obvious. The content of imperatorin significantly increased and the HPLC fingerprint were trending to coincide when the herbs were planted in the same place.


CONCLUSIONS
The environmental factors and the cultivation technique had great influences on the quality of Baizhi.
