TLDR
The structures of isopongglabol and 6-methoxyisopongaglabol have been established as 4′-hydroxyfurano(8,7-4″,5″)flavone and 4′ -hydroxy-6- methoxyfurano (8, 7-4′, 5″)Flavone, respectively, on the basis of the spectral evidence and they have been confirmed by synthesis.About:

SK Pavanaram,Row L Ramachandra +1 more
TL;DR: The furanoflavones, "C " and "D " of Pongamia pinnata (L.) Merr, now named gamatin and pinnatin, were identified by synthesis as 5methoxy-3",4"-methylenedioxy-furano-(3,2,6,7)-flavone and 5-methoxyloxyfurano(3, 2, 6, 7,8) respectively.
