Composition and content analysis of anthocyanidins and proanthocyanidins in ferns

  • In this paper, the contents of anthocyanidins, proanthocyanidins, and total flavonoids in the leaves of 44 species of ferns from 14 families in seven orders were detected. Results showed that all 44 species of ferns contained anthocyanidins. The average content of total anthocyanidins in Polypodiales ferns was significantly higher than that in the other fern orders. Cyanidin, delphinium, and pelargonium were the main anthocyanidin types in ferns. Among them, Blechnaceae ferns were rich in cyanidin and Dryopteridaceae ferns were rich in delphinidin. Most ferns contained proanthocyanidins. The average content of proanthocyanidins in Polypodiales ferns was significantly higher than that in the other fern orders. Thus, the distribution of flavonoids such as anthocyanidins and procyanidins in ferns appears to be related to plant classification. It is speculated that anthocyanidins are related to growth, development, and stress resistance in ferns.
