✦ Synopsis

Abstract

Two new pentacyclic triterpenoids, 3α, 30‐dihydroxylup‐20(29)‐en‐27‐oic acid (1) and (20S)‐3α, 29‐dihydroxylupan‐27‐oic acid (2) were isolated from the whole herbs of Potentilla discolor Bunge. The structures of these two new compounds were elucidated, and complete assignments of the ^1^H and ^13^C NMR spectroscopic data were achieved by 1D and 2D NMR experiments (HSQC, HMBC, ^1^H^1^HCOSY and ROESY).
