摘要：
To investigate differences in the metabolome of the stem bark ofVitex cienkowskiiharvested at three different locations and three different seasons, their extracts were analyzed by means of UPLC-ESI-IMS-TOF MSe. One marker metabolite was isolated and chemically characterized, which was identified as the new compound 20,24-dihydroxy,24-hydroxymethylecdysone (1). IMS showed two drift time species for1which could be used as new and additional characteristic compound parameters in compound identification to reduce dereplication and false positives.
