Steps to reproduce
1. Methanolic extracts from ragweed-pollen samples were prepared. 2. Samples were then analyzed in triplicate by Ultra Performance Liquid Chromatography (UPLC) Ultra-High Resolution (UHR) tandem quadrupole/Time-of-Flight (QqToF) mass spectrometry (MS). 3. From the exported MS data, flavonoids were identified using pure standards of kaempferol-7-O-glucoside, kaempferol, and quercetin (Extrasynthese, France), by library MS/MS match as described in Bertić et al. (2021).
