## Abstract The ^13^C NMR data of six pairs of 18α/18β‐glycyrrhetic acid derivatives are presented. It is shown that the configuration at C‐18 can easily be recognized by inspecting the chemical shifts of several characteristic carbons, e.g. C‐12, C‐13, C‐18 and C‐28. The shifts of these carbons or
