摘要

A glycoconjugatedesignated as LbGp5B was isolated from the fruit of Lyciun barbarum L. and purified to homogeneity by gel filtration .LbGp5B is composed of rhamnose (Rha), arabinose (Ara), galactose (Gal), glucose (Glc), galacturonic acid (GalA) and seveateen amino acids. The molecular weight of LbGp5B was determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and by matrix-asisted laser desorption/ionization (MALDI) time of fight (T OF) mass spectrometry (MS). The preliminary experiments showed that LbGp5B promoted splenocyte proliferation in mice and inhihited the peroxidation of low density lipoprotein (LDL).
