Formation flavonoid secondary metabolites in callus culture of Chrysanthemum cinerariefolium as alternative provision medicine

Abstract

Increasing need of medicine ingredients require the discovery of other methods that can be used as an alternative. One method that can be used as an alternative is tissue culture. Quercetin is a flavonoid secondary metabolites that have been known to be useful as antiviral, anti-asthma and anti-cancer potential. The purpose of this study was to produce flavonoids, especially quercetin in callus culture Chrysanthemum cinerariefolium. Pieces of leaves of plantlets C. cinerariefolium used as explants for formation of callus tissue. To grow the callus, Murashige and Skoog (MS) medium used with addition of various concentrations of growth regulators 2.4-D, and kinetin. For multiplication, callus subcultured on similar medium. Callus that had formed, especially brown callus, further analyzed using Gas Chromatography Mass Spectrum (GCMS). Before analyzed callus was extracted in 95% ethanol. The result showed that callus potentially generate secondary metabolite are brown and friable. Based on these parameters, the best callus produced from leaf explants grown on MS medium with the addition of 4â...mg/L 2,4-D and 0â...mg/L kinetin. The callus contain secondary metabolites such as some of the flavonoid quercetin precursors such as acetic acid and tetrahydroxychalcone, and some other secondary metabolites.
