A new triterpenoid and other compounds from lichens Cryptothecia faveomaculata Makhija & Patw

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.
