ABSTRACT
Objective@#To investigate the changes of alkaloids in Chinese medicine Phellodendron amurense.@*Methods@#High performance liquid chromatographywas used to detect the content of berberine, corkaline, jatrorrhizine, palmatinebefore and after processing in different processed products of Chinese medicine Phellodendron amurense. The column was Ecosil C18 column (250 mm × 4.6 mm, 2.5 μm), and the mobile phase was acetonitrile 0.2% phosphoric acid buffer solution (5545)(0.4 g of sodium lauryl sulfate per 100 ml of 0.2% phosphoric acid aqueous solution), detection wavelength was 265 nm, column temperature was 35 ℃, flow rate was 1.0 ml/min, and injection volume was 3.0 μl.@*Results@#The best processing temperature of brine-dried cork, anthrax, and wine-running cork was below 160 ℃. Themass fraction of total alkaloid was 4.512 7%, 2.789 4% and 4.047 1% at 100 ℃. Among them, the wine-dried cork and salt water-filled cork products and raw products had a high mass indicating that the auxiliary materials for increasing the dissolution rate of alkaloids were salt and wine. Compared with the raw products, the content of berberine and palmatine in salt water-running cork and wine-running cork was obvious. The content of berberine and palmatine in anthrax was significantly decreased, and the content of corkaline and jatrorrhizine did not change significantly.@*Conclusions@#The changes of alkaloids before and after in different processing of Cortex Phellodendron have showed some differences. The different processing and temperature have a direct influence on the changes of its composition, which can changes the chemical properties of Chinese medicine Phellodendron amurense before and after processing.
