Gymnosporia buxifolia (Celastraceae) is a well-known traditional medicinal plant used to treat various diseases. The aim of the study was to quantify the total phenolic and flavonoid content of cell biomass of G. buxifolia developed in vitro using plant growth regulators (PGRs), phloroglucinol (PG) and an antagonist of cytokinin activity 6-(2-hydroxy-3-methylbenzylamino) purine (PI55). The antibacterial activity of calli was also evaluated. The accumulation of phenolic contents and its antibacterial activity in the cell biomass varied between the treatments as well as the mother plant. Generally, a higher accumulation of phenolic contents translated to improved activity against selected pathogenic bacteria. This was apparent in biomass derived from solid and liquid MS media containing combinations of 5 µM PG, 1.5 µM benzyladenine (BA) or meta-topolin (mT) with or without 1 µM picloram (Pic) and 5 µM PG or PI55, 1 µM BA with or without 0.5 µM Pic respectively. The choice of PGRs, PG and PI55 treatments used during in vitro cell culture systems influenced the therapeutic potential of G. buxifolia. Our results indicate that the cell biomass from suspension and/or solid culture of G. buxifolia could be promising as antibacterial agents with possible applications in the pharmaceutical industry.
