Abstract
Three new iridoids, named artselaenin I, II and III, were isolated from the whole plants of Pedicularis artselaeri, along with 11 known compounds, 8-epiloganic acid, 7-deoxy-8-epiloganic acid, plantarenaloside, mussaenoside, lariciresinol-4-O-β-D-glucoside, lariciresinol-4′-O-β-D-gluco-side, alaschaniosideA, cirtusinA, 2-(p-hydroxyphenyl)-ethanol 1-O-β-D-glucopyranoside, 3-methoxy-4-primeverosylacetophenone and adenine. Their structures were identified mainly by spectral evidence.
