MALDI-TOF MS spectral comparisons for triplicate leaf samples of Impatiens glandulifera, processed immediately and after storage for 35 days at − 20 °C, 5 °C, 20 °C, 30 °C, and 40 °C as indicated, for a untreated samples, b acid-soluble proteins extracted from crushed-leaf fluids dried onto filter paper, c acid-soluble proteins extracted from crushed-leaf fluids dried onto filter paper with soaking for 10 min in 70% (v/v) ethanol before re-drying, and d acid-soluble proteins extracted from crushed-leaf fluids dried onto filter paper with soaking for 10 min in 70% (v/v) isopropanol before re-drying
