For the highest analysed value of plant biomass/solvent ratio (0.075 g·mL−1) and maximum process temperature (95ºC), extraction could be carried out for 20 min or in the range 37.1429-38.5714 min. On the other hand, if the extraction time reaches 40 min and the sam-ple/solvent ratio 0.075 g·mL−1, the optimum process temperature is be-tween 75ºC and 95ºC.

Plants belonging to the Apiaceae family (including Levisticum officinale WDJ Koch) are rich sources of phytochemicals and secondary metabolites, with possible health-promoting and agrochemical potential.
