In total, 26 compounds were isolated and identified, of which four are new, namely, two ent-kaurenes (1 and 2), a diterpene lactone (3), and a lindenanolide (4). The previously reported compounds included a series of lindenanolides, guaianolides, elemanolides, and additional diterpenes. The antifungal activity of the isolated compounds was tested against Cryptococcus neoformans and Candida albicans. Among the isolated compounds, the lindenanolides were the only structural class that showed strong antifungal activity, and onoseriolide acetate (5) was the most active. On the other hand, the isolated guaianolides were only moderately active, while the diterpenes did not show significant antifungal activity. © 2014 The American Chemical Society and American Society of Pharmacognosy. 2014 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_01633864_v77_n7_p1579_Fernandez http://hdl.handle.net/20.500.12110/paper_01633864_v77_n7_p1579_Fernandez
