• Abstract:

  Pharmaceutical use is not feasible for important medicinal compounds derived from certain plant materials, including Phyllanthus acuminatus roots, due to their low natural abundance. New technologies in non-traditional biomass generation are needed to produce these remarkable natural compounds. Therefore, this article describes a methodology for establishing Phyllanthus acuminatus plant-cell suspensions from callus cultures: An evaluation on inoculum concentration and agitation speed displayed significant changes in plant cell growth kinetics. It was determined that treatment with 2 g of inoculum in 25 mL of medium and 100 rpm agitation creates the best conditions for generating thick cell suspensions. Likewise, treatment with 2 g of inoculum and 120 rpm agitation produces the best conditions for establishing fine cell suspensions. Phytochemical comparison through high-resolution mass spectrometry of P. acuminatus roots and plant cell suspension extracts confirmed presence in the plant cell culture of multiple phyllantostatins of pharmaceutical interest. Here, we demonstrate that Phyllanthus acuminatus can be cultured in plant cell suspensions to produce secondary metabolites of medical interest – technology that could be scaled up for implementation in industrial bioprocesses.
