Two new 3‐hydroxy‐3‐methylglutaric acid derived phenylpropanoid glucosides, tangshenoside V ( 1 ) and tangshenoside VI ( 2 ), were isolated from the roots of Codonopsis tangshen Oliv ., along with the two known compounds tangshenoside I ( 3 ) and tangshenoside III ( 4 ). Their structures were elucidated by spectroscopic methods (IR and 1D‐ and 2D‐NMR) and by mass spectrometry (HR‐ESI‐MS).
