[Comparative study on main economic characters of different populations of Pinellia ternata in China].
OBJECTIVE
To analyze the content of guanosine, total alkaloid and individual yield of Pinellia ternata from different populations in China and evaluate its quality.


METHODS
Reversed-phase high-performance liquid chromatography (HPLC) was used to determine the content of guanosine. The content of alkaloid was determined by ultra violet spectrophometry. The results were analyzed by SPSS software.


RESULTS
The contents of guanosine and total alkaloid in P. ternata were 0.0136% -0.0264% and 0.0155% -0.0652% respectively. Individual yield was 0.5536-2.9740 g. All of the populations could be classified into 3 types through hierarchical cluster analysis.


CONCLUSIONS
There exist significant differences in the content of guanosine, total content of alkaloid and individual yield of P. ternata from different populations. It is suggested that breeding and selection for type II of P. ternata should be strengthened.
