Abstract: Abstract Two previously unreported compounds, 4-O-(2′′-O-galloyl-β- d -glucopyranosyl)-3,5-dihydroxyacetophenone (1) and 5-isopropyl-2-oxo-3,6-dihydropyran-4-carboxylic acid (2), along with twenty-nine known compounds (3−31) were isolated from the aerial parts of Euphorbia gaditana Coss. Their structures were elucidated based on… read more here.
