Abstract
Pericoterpenoid A (1), a new cadinane-type sesquiterpene, was isolated from an endolichenic fungal strain Periconia sp. (No. 19-4-2-1). Its structure was characterized by analyzing the spectroscopic data (IR, MS, 1D- and 2D-NMR). The antimicrobial activity against Escherichia coli, Staphylococcus aureus, Aspergillus niger, and Candida albicans was evaluated. Pericoterpenoid A showed moderate antimicrobial activity against A. niger and weak activity against C. albicans. This is the first report of the presence of cadinane-type sesquiterpene in Periconia sp.
