Three new cycloartane triterpene glycosides, cycloramosides A-C (1-3), were isolated from Thalictrum ramosum B. Boivin. Those compounds were determined as 3-O-α-l-arabinopyranosyl-3β,16β,24S,25,30-pentaolcycloartane-16-O-β-d-glucopyranoside (1), 3-O-α-l-arabinopyranosyl-3β,16β,24S,25,30-pentaolcycloartane-24-O-β-d-glucopyranoside (2) and 3-O-α-l-arabinopyranosyl-3β,16β,24S,25-tetrahydoxylcycloartane-16-O-β-d-glucopyranoside (3), respectively. Their structures were elucidated by hydrolysis and extensive spectroscopic methods including 1D and 2D NMR experiments (H, C, DEPT, COSY, ROESY, HSQC, HMBC) along with HR-ESI-MS analyses.
