Three new glucosides of phenylpropanoic acid derivatives (micromelumosides A–C) and a new coumarin glucoside (micromelumoside D) were isolated from the aerial portions of Micromelum minutum in addition to 15 known compounds, 3,4-dihydro-1,2-secomicrominutinin 9-O-β-​d-glucopyranside, umbelliferone-​7-​O-​α-​l-​rhamnopyranosyl-​(1 → 6)​-​β-​d-​glucopyranoside, scopolin, haploperoside A, (S)-peucedanol 7-O-β-d-glucopyranoside, (R)-peucedanol 7-O-β-d-glucopyranoside, decuroside V, 4-hydroxy-2,6-dimethoxyphenyl 4-O-β-d-glucopyranoside, vanilloloside, 3,5-dimethoxybenzyl alcohol 4-O-β-d-glucopyranoside, (+)-lyoniresinol 3α-O-β-d-glucopyranoside, (+)-syringaresinol 4-O-β-d-glucopyranoside, kaempferol 3-O-sophoroside, kaempferol 3-O-rutinoside, and citroside B. The structure elucidation of these compounds was based on analyses of spectroscopic data including 1D and 2D NMR.
