Abstract Gall of Rhus chinensis Mill. (Chinese galls) and gall of Quercus infectoria Oliv. (Turkish galls) have similar applications and chemical compositions, and their extracts have been widely used for industrial production and for medicinal applications. In this study, high-performance liquid chromatography–electrospray mass spectrometry (HPLC-ESI-MS/MS) methods were established for profiling the components of Chinese galls and Turkish galls. Compounds representing 96.56 and 99.15% of the total peak area of Chinese galls and Turkish galls were identified. The results identified that the ellagic acid, galloyl-HHDP-glucose and pedunculagin act as the identifying markers for the comparison of Chinese galls and Turkish galls in HPLC-ESI-MS/MS. The peak area of tetragalloyl-glucoside, heptagalloyl-glucoside and pentagalloyl-glucoside can be used to distinguish these two phytomedicines. This work provides a reference for the study of the chemical composition of Chinese galls and Turkish galls, which not only introduce a simple and reliable method to prevent the adulteration or misuse of Chinese galls and Turkish galls but also lay the foundations for clarifying the material basis of their similar pharmacological action.
