Effect of extraction process parameters on the yield of bioactive compounds from the roots of eurycoma longifolia
The effects of extraction process parameters, i.e., extraction time (15-45 min), temperature (40-110°C), particle size (Tongkat Ali roots in chip and powder form), agitation speed (200-400 rpm) and solvent to solid ratio (10:1, 20:1 and 30:1) on the extraction yields from Eurycoma longifolia were in...
