How do you authenticate jasmine sambac concrete and screen for adulteration?
Top authenticates by:
- 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)
- melting point / refractive index / yield against Q/XXXX
- solvent residue confirm (GB 5009.262 not detected)
- Species + "fresh flower / solvent concrete" declaration on COA
- Where required, stable-isotope / spectroscopic naturalness.
