[Influence of heating degrees on internal quality of calcined shell drugs]
Abstract:
The internal quality of 4 kinds of shell drugs calcined under different conditions was investigated and compared in terms of the yielding ratios and total calcium content of the calcined product, Ca2+ content of the decoction and total water-soluble extractive rate. It was found that at calcining temperatures higher than 800 degrees C the internal quality of the shell drugs would change markedly.
