Two new iridoid glycosides, eriobioside ( 1 ) and lamerioside ( 2 ), were isolated from the aerial parts of Lamium eriocephalum subsp. eriocephalum , along with the two known compounds lamiide ( 3 ) and ipolamiide ( 4 ). Their structures were elucidated by spectroscopic methods (UV, 1D‐ and 2D‐NMR) and by mass spectrometry (HR‐ESI‐MS).
