Structural studies of endopolygalacturonase-resistant fragments of an antiulcer pectin from the roots of Bupleurum falcatum L.

The endo-alpha-(1-->4)-polygalacturonase-resistant fractions (PG-1, PG-2, and PG-3) from an antiulcer pectin (Bupleuran 2IIc), isolated from the roots of Bupleurum falcatum L., were further analysed by lithium degradation. The results indicated that PG-1 contained a small proportion of long, branched arabinosyl chains and a large proportion of short… CONTINUE READING
