Abstract： The identification andtraceabilityof Apocynum venetum have long been hampered bytwo major problems.First， Apocynumvenetum'sappearanceand infraredspectrum is extremelysimilar to those offlax and other fiber plants，leading to insufficient discriminationbytraditionalmethods.Second，theprocesingsignificantlyaltersthematerialcompositionof Apocynum venetum，causing interference in traceability.This study investigated Apocynum venetum products at diferent processing stages， with flaxasthecontrolsample，andusesanelementalanalyzer-sotoperatio maspectrometer （EA-MS） to accurately determine their carbon stable isotopes ratio （δ13C） ，hydrogen stable isotopes ratio （δD） ，and oxygen stable isotopes ratio （δ18O） . Furthermore multiple statistical methods， including principal component analysis （PCA），cluster analysis，and partial least squares discriminantanalysis （PLS-DA），were employed for data interpretation.Theresults show thatflax fromdiferentorigins presentsunique isotopic fingerprints.These fingerprintsnotonly effectivelydistinguish processing methods andblending situations but also accurately trace theraw material species andorigin.This paper systematically compares the isotopic variation patterns of Apocynum venetum under different processng techniques， confirmingthat stable isotope technologycan effectivelydistinguish Apocynum venetumandits products，identifyprocessing methods，and trace the origin ofraw materials.This work provides anew technical approach and key data support for the scientific traceability and authenticity identification of natural textiles.
