Abstract
Ten compounds (1-10) were purified from the extract of lichens C. faveomaculata, and among these one new triterpenoid, cryptothecin A (1) was characterized through mass spectrometric and 2D NMR spectroscopic analyses. Some of the isolated compounds were assessed for their antimicrobial (1, 6, and 8) and cytotoxic activity (1, 4-5, and 7-9), but only weak inhibitory effects were observed.
Keywords:
Lichen; antibacterial; steroid; triterpenoid.
