[Comparison of semi-bionic extraction and water extraction in extraction of chemical constituents from processed
1Shandong University of Traditional Chinese Medicine and Pharmacy, Jinan 250014.
Objective:
To Study the granulation of processed Cortex Phellodendri.
Method:
Take berberine, total alkaloids and dry extract as indexes to compare the semi-bionic extraction (SBE) with water extraction (WE).
Result:
In 5 kinds of phellodendron bark solution, berberine, total alkaloids and dry extract obtained by SBE are much better than those obtained by WE.
Conclusion:
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.
