Extracted ion chromatograms acquired using full-scan Orbitrap LC/MS analysis and a 5-ppm window (at the theoretical mass of deprotonated tartaric acid). (A) Lattara no. 4 extract (Top), no. 7 extract (Middle), and tartaric acid standard (Bottom). (B) Lattara pressing platform (Upper) and tartaric acid standard (Lower). The measured accurate masses, indicated in the boxes, are averages taken across the peaks.
