METHOD FOR DETERMINING THE CONTENTS OF OLIGOSACCHARIDES IN MORINDA OFFICINALIS CHINESE MEDICINE OR EXTRACTION THEREOF

摘要

A method for determining the content of oligosaccharides in morinda officinalis comprises the following steps: inspecting by high performance liquid chromatography (HPLC); using the aqueous solution of acetonitrile as the mobile phase; using inulin-type oligosaccharides (5) as the control sample, canculating respectively the content of inulin-type oligosaccharides (3~9) by the peak area based on the external standard method; obtaining the content of the morinda officinalis oligosaccharides by adding the contents of inulin-type oligosaccharides (3~9). In the present invention, while the total content of compounds with similar construction in chemical part is determined by using a single control sample, the single constituent and the respective content thereof are determined.
