title: New coumarin derivative from Euphorbia wallichii.
abstract: One new coumarin derivative (1) and two known compounds, quercetin (2) and glyceraldehyde (3) have been isolated from the whole plants of Euphorbia wallichii. Their structures were elucidated by means of extensive spectroscopic analysis (NMR and ESI-MS) and by comparison with data reported in the literature. This is the first isolation of dihydrocoumarin (1) from the genus of Euphorbia.
