ResumoAbstract The farinose exudate produced on the undersurface of fronds of Notholaena affinis consists of a variety of lipophilic flavonol aglycones. Four of these have been identified as novel interrelated compounds. They all bear methoxyl groups in positions 3,6,7,8 and hydroxyl and/or methoxyl groups at 2′,4′.
