stevia/抗病毒的

Cell wall polysaccharides from leaves of Stevia rebaudiana were extracted successively with water and with aq. 10% KOH. After the purification steps, homogeneous fractions (SFW-10RM and SSFK-10RM) were analyzed by sugar composition, HPSEC, methylation and (13)C NMR spectroscopy analysis. The results

The biological (antiviral) activity of a dried purified extract of Stevia was evaluated in vitro. Tests were performed using Teschen disease virus, infectious rhinotracheitis virus, and human coronavirus.

The antiviral potential of natural polysaccharide compounds has been demonstrated, especially against enveloped viruses and members of the Herpesviridae family. Two polysaccharide fractions obtained from Stevia rebaudiana (Bertoni) leaves, that were active against Herpes simplex virus type 1 (HSV-1)

BACKGROUND Stevia rebaudiana regulates blood sugar, prevents hypertension and tooth decay. Other studies have shown that it has antibacterial as well as antiviral property. METHODS Preliminary phytochemical screening of aqueous, ether and methanolic extracts of S. rebaudiana was done. Acute and
