Abstract
Oligosaccharides A, B, and C (1-3, respectively) were isolated from the ste m of Hoya carnosa. Their structures were established by NMR and chemical me thods. Compounds 1 and 2 were 6-deoxy-3-O-methyl-beta-allopyranosyl( 1-->4) -beta-cymaropyranosyl(1-->4)-beta-cymaropyranosyl(1-->4)-beta-cymaronic aci d delta-lactone and 6-deoxy-3-O-methyl-beta-allopyranosyl(1-->4)-beta-olean dropyranosyl(1-->4)-beta-cymaropyranosyl(1-->4)-beta-cymaronic acid delta-l actone, respectively. Compound 3 was the sodium salt of 2.
