Hyoscyamine, anisodamine (6â-hydroxyhyoscyamine) and scopolamine are tropane alkaloids produced by plants belonging to the Solanaceae family such as Brugmansia candida. These alkaloids were traditionally used in medicine because of their anticholinergic activity. Further therapeutical properties for anisodamine were recently described renewing the interest in these alkaloids. The scaling-up of hairy root cultures is an interesting strategy for the pharmaceutical production of these compounds instead of the isolation from plants. In this work, B. candida hairy roots were cultured in a modified 1.5 L stirred tank in order to analyze an alternative production system of scopolamine and anisodamine. It was found that these cultures produced an increased biomass and alkaloids concentration compared to the processes carried out in Erlenmeyer flasks. Anisodamine was the predominant alkaloid reaching a maximum concentration of 10.05±0.76 mg/g DW in modified bioreactor culture system. The results obtained in this work are potentially applicable for the rational scale-up of the process.
