Comparison of Extraction Methods for the Quantification of Phytohormones From Tomato Fruits and Leaves by LC–MS/MS

ABSTRACT Purification of crude plant extracts by solid‐phase extraction (SPE) is assumed to reduce matrix effect in phytohormone quantification by LC–MS/MS, but its efficacy is rarely assessed. We used postextraction spiking of isotope‐labeled phytohormones to estimate matrix eff...
