Aucubigenin has shown antibacterial activity against Staphylococcus aureus, Proteus mirabilis, and Bacillus subtilis. It also displays antifungal effects against Candida albicans and Penicillium italicum, along with anti-hepatitis B virus properties.

Hepatoprotective:
Aucubigenin can inhibit hepatic RNA polymerase and protein synthesis, offering protection against liver toxins like carbon tetrachloride and alpha-amanitin.
