4. Conclusion

The present work showed that SA enhanced the secondary metabolism of the PAL and TAT enzymes and the antioxidative activities of the SOD, CAT, and POD enzymes. In addition, this work showed that SA could elicit the accumulations of phenolic compounds. However, the SA elicitation effect is depended upon the SA concentration and the time-duration. The SA-induced phenolic compound accumulations are related to the PAL activity and not to the TAT activity. This suggests that in the S. miltiorrhiza cell cultures PAL may be the key enzyme involved in the biosynthesis of both salvianolic acid B and caffeic acid. The SA application stimulated the PAL activity, which lead to the enhanced accumulations of phenolic compounds. This could be of particular significance in using plant cell culture systems for the biotechnological production of both salvianolic acid B and caffeic acid from the S. miltiorrhiza cell cultures. As promising as these preliminary results may be, the relationships between SA, secondary metabolism, and the related enzymes are far from being completely understood and further investigations are needed to clarify the underlying mechanisms.
