Meroterpenoids and alkaloids from Ganoderma australe

Natural Product Research, 2019
Two new mertoterpenoids, australins A (1) and B (2), and a new alkaloid, australine (4), together with five known compounds (3, 5–8) were isolated from the fruiting bodies of Ganoderma australe. Their structures including absolute configurations were assigned by using spectroscopic methods and electronic circular dichroism (ECD) calculations.
