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 effects of some of the compounds from d-galactosamine-induced cytotoxicity in HL-7702 hepatic cells were evaluated. Compounds
