Fig. 6From: Comparative metabolomics reveals the metabolic variations between two endangered Taxus species (T. fuana and T. yunnanensis) in the HimalayasDetermination of the contents of total and individual flavonoids in T. fuana and T. yunnanensis. a The contents of total flavonoids in T. fuana and T. yunnanensis. b The contents of eight individual flavonoids in T. fuana and T. yunnanensis. A P value < 0.001 was considered to be statistically significant and indicated by “*”. c Chromatograms of individual flavonoids in negative mode. d Chromatograms of individual flavonoids in positive mode.
