Six Rhodiola crenulata samples collected from different places in Tibet were extracted by methanol and analyzed using UPLC-ESI-MS/MS in negative-ion mode. In addition to 12 compounds identified based on quasi-molecular ion and MS2 fragment ions
the differences of the relative content of related compounds were compared. The results showed that there were obvious differences in the composition of identified compounds in herbs with different collection places.
