Chemical components of two Japanese ferns were studied. From the leaves of Sphenomeris chusana, vitexin (a flavonoid compound), syringic acid, protocatechualdehyde, and protocatechuic acid were isolated and identified. From the leaves of Cyathea Fauriei, vitexin was isolated and identified. This is the first occurrence of vitexin in ferns.
