Kinetin Induced Changes in Rutin Content in Knautia sarajevensis (G. Beck) Szabó Shoot Cultures

Abstract

Knautia sarajevensis (Dipsacaceae), endemic to Dinaric Alps, is traditionally used for pharmacologically active substances. Cytokinin effects on flavonoid concentrations (quercetin, naringenin, hesperetin, rutin) were analyzed in in vitro shoot cultures using control, 1.0 mg/L kinetin, and 10.0 mg/L kinetin treatments. High cytokinin concentrations improved rutin content, though remaining below control levels. Further investigation with different cytokinins is needed.
