Sobre IBD

Antocyjany stanowią klasę związków chemicznych, które często kojarzone są z barwieniem gatunków roślin. Grupa ta występuje w różnych częściach rośliny, takich jak łodyga, kwiat, owoc, liść i inne. W niniejszej pracy oceniono zawartość antocyjanów w ekstraktach etanolowo-wodnych z gatunków kwiatów Allamanda laevis (alamanda żółta), Hibiscus rosa-sinensis (hibiskus), Centrosema brasilianum (fasola dzika), Ixora coccínea (ixora), Senna alata (mangerioba do pará), Ipomoea glabra (gitirana), Tithonia diversifolia (mini-girassol) i Tabebuia avellanedae (ipê roxo). Badanie obejmuje również uzyskanie zestawienia zawartości antocyjanów w każdym gatunku oraz ich zdolności jako wskaźników kwasów i zasad. Wstępnie oceniono ekstrakty w celu oszacowania stężenia antocyjanów w nich obecnych. Na podstawie powyższych ustaleń można stwierdzić istnienie bezpośredniego związku między zmianą zabarwienia a zawartością antocyjanów.
