Four Pentasaccharide Resin Glycosides from Argyreia acuta

Four pentasaccharide resin glycosides, acutacoside F-I ( - ), were isolated from the aerial parts of . These compounds were characterized as a group of macrolactones of operculinic acid A, and their lactonization site of 11 -hydroxyhexadecanoic acid was esterified at the second saccharide moiety (Rh...

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