New Antibacterial Diterpenoids from the Sarcodon scabrosus Fungus

Abstract

  The structures of new antibacterial diterpenoids that had been isolated from Sarcodon scabrosus were established by chemical and spectral means to be sarcodonin L (2) and M (3), both having the cyathane skeleton. Other antibacterial compounds were identified to be allocyathin B₂ (1), sarcodonin G (4) and sarcodonin A (5) by comparing their spectral data with those of authentic samples.
