Nine new acyl glycosides, obtusifosides A-I (1-9), and eight known compounds have been isolated from an EtOH extract of the stems of Erycibe obtusifolia. Their structures were elucidated on the basis of a spectroscopic data analysis (NMR, HRESIMS, and CD) and chemical evidence. The hepatoprotective
Three new acyl glycosides with rare β-D-apiofuranosyl-(1→2)-[β-D-apiofuranosyl-(1→6)]-β-D-glucopyranosyl moieties, 2-O-[2,6-O-bis(5-O-syringoyl-β-D-apiofuranosyl)-β-D-glucopyranosyl]-isopropyl alcohol (1), 1-O-[2,6-O-bis(5-O-syringoyl-β-D-apiofuranosyl)-β-D-glucopyranosyl]-isoamyl alcohol (2), and
Three new quinic acid derivatives, 4-O-caffeoyl-3-O-sinapoylquinic acid methyl ester (1), 5-O-caffeoyl-4-O-syringoylquinic acid methyl ester (2), and 4-O-caffeoyl-3-O-syringoylquinic acid methyl ester (3), as well as four new coumarin glycosides,
