Resveratrol and its derivatives are natural stilbenes associated with many health benefits that include those conferred by their antioxidant and anticancer properties. While stilbenes can be recovered as an extract from a selected number of plants, these products are not suitable for many applications in the food/pharmaceutical sectors due to high levels of impurities as well as the overall low concentration of resveratrol and its derivatives in the extract. To deliver a highly defined and enriched resveratrol product, hairy root cultures of peanut (Arachis hypogaea) were established and tested as a bioproduction system for resveratrol and associated derivatives. Analyses by HPTLC and GC-MS of ethyl acetate extracts showed that a single 24 h sodium acetate elicitation resulted in a 60-fold induction and secretion of trans-resveratrol into the medium of peanut hairy root cultures. trans-Resveratrol accumulated to levels of 98 microg/mg of the dried extract from the medium representing 99% of the total resveratrol produced. Other stilbenes, including trans-pterostilbene, were also detected in the medium. Our results demonstrate the capacity of hairy root cultures as an effective bioprocessing system for valued nutraceuticals like resveratrol and resveratrol derivatives. In being able to effectively induce and recover high levels of resveratrol and associated derivatives from the media fraction, hairy roots may offer a scalable and continuous product recovery platform for naturally-derived, high quality, enriched nutraceuticals.
