A new chromone from Ficus lyrata.
A new chromone, named 5,6-dihydroxy-2-methylchromone (FL-2), along with seven known flavonoids, 5-hydroxy-7,3,3',4'-tetramethoxyflavone (FL-3), 5,4'-dihydroxy-6,7,8-trimethoxyflavone (FL-4), 5,4'-dihydroxy-7,8-dimethoxyflavone (FL-5), 4-methoxychalcone (FL-6), 7,4'-dimethoxyapigenin (FL-7), 5,7,4'-trihydroxy-2',3',6'-trimethoxyisoflavone (FL-8 a rare flavonoid), acacetin-7-O-glucoside (FL-9) and acacetin-7-O-neohesperidoside (FL-10), and beta-sitosterol-D-glucoside (FL-1) have been isolated from the leaves of Ficus lyrata. Their structures have been established on the basis of chemical and spectral evidence (IR, UV, 1H NMR, 13C NMR and mass spectra).
