Objective:
To study on the antidepressive extraction and determinated the content of the oligosaccharides I , the proteins and the trace elements from Morinda officinalis.
Methods:
We analyzed the content of the total oligosaccharides, the proteins and the trace elements by Phenol-Sulferic acid, Coomassie brilliant blue and inductive coupling plasm atomic emission spectrometer (ICP-AES) methods, respectively.
Results:
The percent of the oligosaccharides and the proteins were 89.4% and 0.19% in the extraction from M. officinalis, respectively. The total actively oligosaccharides I were subjected to the D-941 ion column chromatography to give the extraction in which hardly and protein were determined. 12 kinds of trace element including Zn, Fe, Ca ect. in the extraction (the oligosaccharides I) were determined by ICP-AES without the noxious trace elements including As, Cd, Pb ect.
Conclusion:
The antidepressive activity extraction(the oligosaccharides I ) was a highly pure and vegetal oligosaccharides.
