The study focused on the production of compounds with antioxidant activity in hairy root and shoot cultures of Salvia officinalis grown in laboratory-scale sprinkle nutrient bioreactors. HPLC analysis showed that production of rosmarinic acid in transformed roots (34.65±1.07 mg l-1) was higher that in shoot culture (26.24±0.48 mg l-1). In the latter diterpenoids: carnosic acid (1.74±0.02 mg l-1) and carnosol (1.34±0.01 mg l-1) were also found. Biomass accumulation after a growth period in the bioreactor was also studied. An 18-fold increase in hairy root biomass was recorded after 40 days of culture. In sage shoot culture, biomass increased 43 times after 21 days of bioreactor run. The current operating conditions of the bioreactor were not suitable for the propagation of Salvia officinalis mainly due to the hyperhydricity problem of leaves and stems.
