Antiviral Terpenoid Constituents of Ganoderma pfeifferi.


Four sterols and 10 triterpenes were isolated from the fruiting bodies of Ganoderma pfeifferi, including the three new triterpenes 3,7,11-trioxo-5alpha-lanosta-8,24-diene-26-al (lucialdehyde D, 1), 5alpha-lanosta-8,24-diene-26-hydroxy-3,7-dione (ganoderone A, 2), and 5alpha-lanosta-8-ene-24,25-epoxy-26-hydroxy-3,7-dione (ganoderone C, 3). The structures of 1-3 were determined on the basis of spectroscopic evidence. Antibacterial, antifungal, and antiviral activity were studied for some of the isolated compounds. Ganoderone A (2), lucialdehyde B (4), and ergosta-7,22-dien-3beta-ol (7) were found to exhibit potent inhibitory activity against herpes simplex virus.
