Abstract
Eurycoma longifolia Jack or tongkat ali is a medicinal plant that has been long used in Southeast Asia, including Indonesia. The demand of tongkat ali extract is increasing, therefore the bigger production system is needed. The increment of production required a growth kinetics model hence biomass production and secondary metabolite production can be estimated. In order to enhance the production of secondary metabolites, UV elicitation method could be applied.
In this study, cell suspension cultures were g
