Organ‐Specific Volatile Profiling of Lactuca tatarica (L.) C.A.Mey. (Asteraceae) Reveals Metabolic Differentiation by MSD–SPME–GC–MS/FID

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
MSD–SPME–GC–MS/FID reveals distinct organ‐specific volatile signatures in Lactuca tatarica. Leaves are dominated by lipid‐derived aldehydes, roots exhibit a mixed profile of aldehydes and terpenoids, and seeds are characterized by aldehydes and aromatic ketones.
