Abstract

Radix Scrophulariaceae is an herbal medicine used as antipyretic and antibacterial. The objective of this study was to investigate the effect of high temperature stress on the secondary metabolites of Scrophularia ningpoensis Hemsl (S. ningpoensis). Potted S. ningpoensis plants of three ecotypes in florescence were subjected to high temperature stress for 15 days. Results showed that under high temperature stress, contents of iridoid glycosides and cinnamic acid in S. ningpoensis roots were significantly lower than the control in all ecotypes. The present study indicates that high temperature stress has an obvious inhibitory effect on the production of iridoid glycosides and cinnamic acid.

 

Key words: Scrophularia ningpoensis, secondary metabolites, cinnamic acid, iridoid glycosides.
