[Studies on stimulating components of raw Pinellia ternata (Thunb.) (banxia)].
OBJECTIVE
To study the stimulating components of raw Pinellia ternata (Banxia).


METHODS
Used the methods of extracting with various organic solvents; x-ray fluorescence spectrometer; scanning electron microanalyzer; oxidation and reduction titrations; and ultraviolet spectrophotometry.


RESULTS
Experiments showed that calcium oxalate hydrate (C2CaO4 x H2O) was one of the stimulating components of raw Pinellia ternata, and its shape, and contents related to the stimulation of raw Pinellia ternata. After processing, the shape and contents of calcium oxalate changed, decreased respectively, and the stimulation of Pinellia ternata decreased.


CONCLUSIONS
The needle crystal of calcium oxalate is one of the stimulating components in raw Pinellia ternata.
