[Comparison of semi-bionic extraction and water extraction in extraction of chemical constituents from processed cortex Phellodendri].
OBJECTIVE
To Study the granulation of processed Cortex Phellodendri.


METHODS
Take berberine, total alkaloids and dry extract as indexes to compare the semi-bionic extraction (SBE) with water extraction (WE).


RESULTS
In 5 kinds of phellodendron bark solution, berberine, total alkaloids and dry extract obtained by SBE are much better than those obtained by WE.


CONCLUSIONS
In the preparation of oral granules from processed Cortex Phellodendri, SBE is superior to WE, when the pH value is adjusted by HCl solution to 1.0 in the first decoction, adjusted by saturated Ca(OH)2 solution to 7.0 in the second decoction and to 10.0 in the third decoction respectively.
