[Content variation of saponins and flavonoids from growing and harvesting time of Glycyrrhiza uralensis].
OBJECTIVE
Determining and comparing the saponins and flavonoids contents in Glycrrrhiza uralensis Fisch to know theObjective: Determining and comparing the saponins and flavonoids contents in Glycyrrhiza uralensis Fisch to know the dynamic variation.


METHODS
The contents were determined by ultraviolet spectrophotometry.


RESULTS
Two contents had basically theMethods:The contents were determinedby ultraviolet spectroihotometry. Results: Two contents had basically the same change cultivated in Gansu and Inner Mongolia.


CONCLUSIONS
The plant 3-year cultivated has the highest content. Having high con-same change cultivated in Gansu and Inner Mongolia. Conclusion:The plant 3-year cultivated has the highest content. Having high content of Saponins in August and flavonoids in May and October which can be used as the basis for harvesting and processing.
