Abstract:
Objective:To investigate the effects of some culture conditions on production of asiaticoside from centella (Centella asiatica L. Urban) cells cultured in 5-L bioreactor.
Methods: The centell cell suspension culture was conducted in 5-L bioreactor to investigate the growth and asiaticoside accumulation under various conditions. Asiaticoside content was determined by HPLC analysis.
Results:The results showed that the cell growth and asiaticoside accumulation peaked after 24 d of culture at an agitation speed of 150 r/min and aeration rate of 2.5 L/min. The cell biomass reached a maximum value of 302.45 g fresh weight (31.45 g dry weight) and growth index of 3.03 with inoculum size of 100 g. However, asiaticoside content was the highest (60.08 mg/g dry weight) when culture was initiated with an inoculum size of 50 g.
Conclusions: The present study found the suitable conditions for growth of centella cells and their asiaticoside production in bioreactor.
