(-)-Semivioxanthin, a new abscisic active compound against Hinoki cypress leaves isolated from Cryptosporiopsis abietina.
The new naphthopyrone, (-)-semivioxanthin (1) was isolated from Cryptosporiopsis abietina. The structure of 1 was determined as the reversed optical isomer of semivioxanthin by comparing its spectroscopic data with those of semivioxanthin. Compound 1 exhibited abscisic activity against Hinoki cypress leaves and antifungal activity against Cladosporium herbarum.
