Abstract

Berberine from crude and processed Phellodendron chinense was determined by UV TLC densitometry. The results indicate that the content of berberine in processed products is 11.8% to 98% less than that of the crude drug. The recovery of berberine is 98% +/- 1.7% and the Standard relative deviation is 1.7%.
