From the fronds of Alsophila spinulosa TRYON biflavonoids Hegoflavone A (I) and B (II) were isolated and their structures were elucidated by spectroscopic analysis and chemical degradation to be 2, 3-dihydro-3'''-hydroxy-6, 6'''-biapigenin (I) and 2, 3-dihydro-6, 6'''-biluteolin (II) respectively. These are the first reports of a C-6/C-6'''-linked biflavonoid in nature.
