Objective: To investigate effects of different processing methods on concents of oligosaccharides and monotropein in Morindae Officinalis Radix. Method: Processed products of Morindae Officinalis Radix were prepared by different methods
contents of oligosaccharides and monotropein in different processed products were compared.The content of oligosaccharides was determined by HPLC-CAD with Shodex Asahipak NH2 column
mobile phase of acetonitrile(A)-water(B) for gradient elution (0-15 min
86%-81%A;15-20 min
81%-75%A;20-35 min
75%-70%A;35-50 min
70%-58%A;50-60 min
58%-40%A;60-65 min
40%-20%A);the content of monotropein was determined by HPLC-DAD with Venusil MP C18 column
mobile phase of methanol-0.4% phosphoric acid for gradient elution (5:95-28.8:71.2
15 min) and detection wavelength at 235 nm. Result: The content of oligosaccharides was in the order of Morindae Officinalis Radix steamed by salt >Morindae Officinalis Radix without the wood >Morindae Officinalis Radix processed with Glycyrrhizae Radix et Rhizoma >crude Morindae Officinalis Radix;while according to the content of monotropein was Morindae Officinalis Radix steamed by salt >crude Morindae Officinalis Radix >Morindae Officinalis Radix processed with Glycyrrhizae Radix et Rhizoma >Morindae Officinalis Radix without the wood. Conclusion: Processing could greatly change contents of oligosaccharides and monotropein in Morindae Officinalis Radix
which provided a reference for pieces quality control and processing mechanisms analysis of Morindae Officinalis Radix.
