Vitexin isomers, apigenin-8-C-hexoside-O-rhamnoside and isoorientin were the most common polyphenols in leaves an flowers, with stems having high contents of proanthocyanidins. Even after in vitro digestion extracts showed activity against free radicals with leaf and flower extract exerting the highest activity.
The presence of Vitamin C in the plant was confirmed by enzymatic method.
The plant grows on Madeira Island and the Western Canary Islands of Tenerife, Gran Canaria, La Palma, La Gomera and El Hierro.
