Rosmarinic acid biosynthesis in callus and cell cultures of Agastache rugosa Kuntze

Abstract

Callus and cell suspension cultures of Agastache rugosa were established to investigate the production of rosmarinic acid in vitro. For callus induction 2,4-D treatment was more effective than that of NAA. The best callus induction rate (92%) and callus growth A. rugosa were obtained in MS medium containing 2 mg/l 2, 4-D. In cell suspension culture of A. rugosa, the maximum growth (7.7 g/l) and the highest rosmarinic acid production (11.5 mg/g) were attained in the liquid B5 medium supplemented with 2 mg/l 2,4-D and 0.1 mg/l BAP at 10 days after culture. The present results demonstrate that cell culture of A. rugosa might be an alternative approach for the production of rosmarinic acid.   Key words: Agastache rugosa, callus, cell suspension, rosmarinic acid.
