Discrimination of leaves of Panax ginseng and P. quinquefolius by ultra high performance liquid chromatography quadrupole/time-of-flight mass spectrometry based metabolomics approach.

Highlights: [•] UHPLC–QTOF-MS/MS based metabolomics approach developed to find characteristic markers of LPG and LPQ leaves. [•] Nine characteristic chemical markers for discriminating LPG and LPQ leaves were revealed for the first time. [•] The metabolic profiles of LPG and LPQ leaves were also systematically investigated. [Copyright &y& Elsevier]
