[Determination of polysaccharide from Chinese medicine Morinda officinalis how and its trace elements analysis].
Polysaccharide was extracted from morinda officinalis how by back-flowing with 80% ethanol for 1 h, and the method of improved phenol-sulfuric acid spectroscopy was adopted to determine the content of morinda officinalis how polysaccharide. As for its trace elements, the atomic absorption spectroscopy was used to detect the content of Zn, Fe and Cu, which were compared with its fake; and cold atomic fluorometry was applied to determine the trace mercury. The results were satisfactory, which can give reference about the effective components of morinda officinalis how, and will help to exploit it.
