The effects of sucrose, indole-3-acetic acid (IAA) and 6-benzylaminopurine (BAP) concentrations on cell growth of Centella Asiatica cell suspension culture were studied. The concentrations were designed using Central-composite experimental design and regression analysis was carried out to obtain response surface model describing cell growth for prediction of optimum conditions. Only sucrose as a single factor was positively significant on cell growth. Increasing sucrose concentration from 3.32 to 6.68% (w/v) resulted in an increase in dry cell weight from 16 to 27 g L-1. IAA and BAP as single factors and other possible interactions effect were insignificant. The optimum values predicted were 6.68% (w/v) sucrose, 0.84 mg L-1 IAA and 1.17 mg L-1 BAP yielding 27.4 g L-1 dry cell weight with 81.4% regression equation fitness to the experimental data.
