Antiviral: Administration of moronic acid from Wu Bei Zi is associated with antiviral effect. The main active compounds include rhuscholide A, betulonic acid, moronic acid, and others.
Wu Bei Zi (Galla Chinensis) contains tetra-O-galloyl-β-D-glucose (TGG) and luteolin, were identified to exhibit prominent anti-SARS virus activity. These natural molecules bound avidly with the surface spike protein of SARS virus and thus interfered with the entry of the virus to its host cells.
