Technical Abstract: The caffeoyl ester rosmarinic acid (RA) synthesized in the phenylpropanoid pathway exhibits several proven medicinal properties. RA is constitutively synthesized in spearmint (Mentha spicata L.) plantlets grown in vitro and its content can be manipulated by nutritional and physical treatments. Carbon applications (atmospherically or nutritionally) readily increase RA yields in vitro. For example, spearmint plantlets grown under 10,000 'L CO2 L-1 exhibited a 5-fold increase in RA levels over untreated controls. Similarly, applications of high sugar levels applied to the media dramatically increased RA levels also. Enhanced carbon environments allow for enhanced plantlet growth (fresh weight), morphogenetic responses (leaves, roots and shoots) and secondary metabolism (RA).
