Effects of sucrose concentrations on the growth and production of puerarin and isoflavones compounds in Pueraria phaseoloides hairy roots induced by Agrobacterium rhizogenes ATCC15834 were investigated. Changes of sucrose consumption in the medium during liquid culture were also determined. The results showed cultured for 16 days in MS medium with 5%, 4%, 3% and 2% sucrose, the proliferation times of dry weight of hairy roots were 11.7, 11.9, 10.1 and 5.9, respectively. 3% sucrose concentration in liquid medium was the best for accumulation of puerarin and isoflavones in the hairy roots. The highest content of puerarin, 5.147 mg/g DW, was obtained after 12 days of liquid culturing while the highest content of isoflavones, about 27.76 mg.g.DW, was gained after 16 days in culturing. Sucrose concentration decreased as hairy root growth proceeded. The growth rate and the content of soluble sugar in hairy roots of P. phaseoloides was directly proportional to the rate of sucrose utilization in the liquid medium during the whole culture. It was observed that the highest content of soluble sugar in hairy roots was at day 12 of liquid culture and sucrose in the liquid medium was used up at the end of 16 days of culture.
