How do you authenticate jasmine sambac concrete and screen for adulteration?
Top authenticates by: (1) GC-MS benzyl alcohol / benzyl acetate / indole floral fingerprint matched to natural jasmine sambac (the ratio of benzyl alcohol, benzyl acetate, indole, cis-jasmone, methyl jasmonate is the signature; synthetic jasmine lacks the jasmone/jasmonate trace complex); (2) melting point / refractive index / yield against Q/XXXX; (3) solvent residue confirm (GB 5009.262 not detected); (4) species + "fresh flower / solvent concrete" declaration on COA; (5) where required, stable-isotope / spectroscopic naturalness. Every lot ships with COA plus GC-MS. We screen synthetic-jasmine / other flower-wax padding / carrier dilution by the floral fingerprint. Lots failing the natural jasmine sambac indolic profile are blocked.
