| 摘 要： | An oligosaccharide homologue named SnS-2 was isolated from the root of Scrophularia ningpoensis Hemsl.SnS-2 was purified by means of gel-permeation chromatography and ion-exchange chromatography. Its physicochemical properties, including carbohydrate content and molecular weight were determined. The structure of SnS-2 was elucidated by chemical methods along with ^1H and ^13C NMR spectroscopy, including two-dimensional DQCOSY and H-detected ^1H, ^13C HMQC experiments. These results show that SnS-2 possesses a backbone consisting of terminal α-Galp-(1→, α-Galp-(1→6), α-Glcp-(1→6) and nonreducing end β-Fruf-(2→. The bioactive assay showed that it could inhibit the growth of Lewis pulmonary carcinoma implanted in mice.

| Abstract: | An oligosaccharide homologue named SnS‐2 was isolated from the root of Scrophularia ningpoensis Hemsl. SnS‐2 was purified by means of gel‐permeation chromatography and ion‐exchange chromatography. Its physico‐chemical properties, including carbohydrate content and molecular weight were determined. The structure of SnS‐2 was elucidated by chemical methods along with 1H and 13C NMR spectroscopy, including two‐dimensional DQCOSY and H‐detected 1H, 13C HMQC experiments. These. results show that SnS‐2 possesses a backbone consisting of terminal α‐Galp(1→, α‐Galp‐(1→6), α‐Glcp‐(1→6) and nonreducing end β‐Furf‐(2→. The bioactive assay showed that it could inhibit the growth of Lewis pulmonary carcinoma implanted in mice. |
