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