Production of asiaticoside from centella (Centella asiatica L. Urban) cells in bioreactor.
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.
