Pyranoisoflavones
  • Alpinumisoflavone
  • Di-O-methylalpinumisoflavone
  • 4'-methyl-alpinumisoflavone
  • 5,3′,4′-trihydroxy-2″,2″-dimethylpyrano (5″,6″:7,8) isoflavone - has antifungal properties, and is from the plant species ficus tikoua Bur.[2]

The enzyme monoprenyl isoflavone epoxidase produces a dihydrofurano pyranoisoflavone derivative from 7-O-methylluteone.
