Abstract:
This paper was aimed to explore the relationship between different commercial specification and chemical constituents on Radix Rehmanni,which provided experimental evidences for drawing up the commodity commercial specification and grading criteria of Radix Rehmanni.Several classified indexes,including grade,surface color,section color,section texture were carried to explore the change rules of chemical constituents by setting the contents of iridoid glycoside,sugars,water content,total ashes,acid-insoluble ashes and water extract as the markers.The results showed that the grade,surface color and section texture had less impact on chemical constituents.However,the section color had more influence.Along with the section color gradually being deepened,the contents of iridoid glycoside and oligosaccharides of Radix Rehmanni were lower,and the contents of monosaccharide and polysaccharide were higher.It was concluded that there was correlation between commercial specification and chemical constituents of Radix Rehmanni.
