ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influence of 2,3-dihydrocyclopenta coumarins to the growth of transgenic hairy root of Polygonum multiflorum and the accumulation of active ingredient stilbene glucoside in the culture.</p><p><b>METHOD</b>In different culture time, 2,3-dihydrocyclopenta coumarin compounds were administrated to the hairy roots. The yield of stilbene glucoside and the growth of the hairy roots were determined after some period of co-culture. Through the investigation of the different concentrations of the 2,3-dihydrocyclopentacoumarin, and sub-culture times, the optimal experimental conditions were established.</p><p><b>RESULT</b>The optimal administration time of the 2,3-dihydrocyclopentacoumarin was on the fourth day, the optimal concentration of 2,3-dihydrocyclopentacoumarin was 0.025 g x L(-1). Under this condition, the growth of the hairy root greatly increased. Comparing with control group, the accumulation of stilbene glucoside was increased about four times.</p><p><b>CONCLUSION</b>2, 3-dihydrocyclopentacoumarins could promote the hairy hair root growth and stimulate the stilbene glucoside accumulation.</p>
