Metabolic profiling and antioxidant activity during flower development in Agastache rugosa.

ABSTRACT: Our previous study showed that flowers of Agastache rugosa had higher phenolic levels and higher antibacterial and antioxidant capacity compared to those of the leaves and stems. The aim of this study was to provide information on the variation in primary and secondary metabolites during flower development in A. rugosa by using high performance liquid chromatography (HPLC) and assays of total anthocyanin (TAC), flavonoid (TFC), and phenolic content (TPC), as well as gas chromatography time-of-flight mass spectrometry (GC-TOFMS) analysis. Assays of TPC, TAC, and TFC showed that the floral bud (stage I) contained higher TPC than did the partially open flower (stage II) and fully open flower (stage III). However, the TFC was the highest at stage II, and the highest TAC was obser
