- Abstract
Four pentasaccharide resin glycosides, acutacoside F-I ( 1 - 4 ), were isolated from the aerial parts of Argyreia acuta . These compounds were characterized as a group of macrolactones of operculinic acid A, and their lactonization site of 11 S -hydroxyhexadecanoic acid was esterified at the second saccharide moiety (Rhamnose) at C-2. The absolute configuration of the aglycone was S . Their structures were elucidated by established spectroscopic and chemical methods.
