Contents Change of Alkaloids in Coptidis Rhizoma by Different Proportions of Compatibility with Ginseng Radix et Rhizoma
Objective:To investigate contents change of jatrorrhizine hydrochloride and berberine hydrochloride in decoction by different proportions of compatibility of Coptidis Rhizoma and Ginseng Radix et Rhizoma. Method:Coptidis Rhizoma and Ginseng Radix et Rhizoma were made up a prescription by proportions of 2:1
1.5:1
0.5:1
respectively;HPLC was adopted to determine contents of alkaloids in decoction. Result:The content of berberine hydrochloride were 36.68
39.41
44.33 mg·g-1 in different proportions of compatibility of Coptidis Rhizoma and Ginseng Radix et Rhizoma
while the content of jatrorrhizine hydrochloride were 8.607
8.349
10.790 mg·g-1
these two components increased with decreasing dosage of Ginseng Radix et Rhizoma. Conclusion:Compatibility of Coptidis Rhizoma and Ginseng Radix et Rhizoma was not beneficial to dissolution of berberine hydrochloride and jatrorrhizine hydrochloride
compatibility of 0.5:1 was most beneficial to dissolution of these two ingredients.
