Anti-Inflammatory, Antiulcer and Anticancer Activities of Saponin Isolated from the Fruits of Ziziphus jujuba

Abstract

Background: Ziziphus jujuba mill was commonly used for its anti-inflammatory activity in traditional system of medicine. Objective: The purpose of this study was to examine the isolates of methanolic extract from the fruits of Ziziphus jujuba Mill for its antiulcer, anti-inflammatory, and anticancer activity. Methods: Methanolic extracts of Ziziphus jujuba Mill were subjected to chromatography and eluted using ethyl acetate: methanol mixture and investigated for its structural features using IR, 1H NMR, 13C NMR and mass spectral data. The isolated compound was evaluated for its in vitro COX-2 inhibition studies, cytotoxicity studies, in vivo anti-inflammatory, antiulcer and anticancer activity. Results: The spectral data revealed that the backbone of the isolate was 3-O-α-L-rhamnopyranosyl- (1→6)-β-D-glucopyranosyl jujubogenin-20-O-(2,3,4-O-triacetyl)-α-L-rhamnopyranoside. The isolated compound showed a significant reduction in inflammation and edema. Moderate anticancer activity was also observed for the isolate. Conclusion: It was concluded that the isolated saponin possesses moderate antiulcer, antiinflammatory, and anticancer activity which could help in the identification of leads for the treatment of cancer-related inflammation.
