Abstract
Two novel bidesmosidic cycloartane-type glycosides, depressosides C and D were isolated from Corchorus depressus L. Their structures were elucidated as (22R)-16β, 22-epoxy-3β, 26-dihydroxy-9, 19-cyclolanost-24E-ene 3, 26-di-O-β-D-glucopyranoside and (22R, 24S)-22, 25-epoxy-3β, 16β-24-trihydroxy-9, 19-cyclolanostane 3, 24-di-O-β-D-glucopyranoside, respectively on the basis of chemical evidence and detailed spectroscopic studies.
