| Abstract
| - The roots of Delphinium denudatum have yielded a newditerpenoid alkaloid, 8-acetylheterophyllisine (1), in addition to the known alkaloidsvilmorrianone (2), panicutine (3),denudatine(4), isotalatizidine (5), and condelphine(6), as well as 3-hydroxy-2-methyl-4H-pyran-4-one(7).Compounds 1, 3, and 7 have notbeen isolated from this plant previously. The structuresofcompounds 1, 3, and 7 were determinedthrough spectral and X-ray diffraction analyses.Compounds 1−3 have shown antifungal activity againsta number of human pathogenic fungi.
