How do you authenticate osmanthus concrete and screen for adulteration?
Top authenticates by:
- GC-MS β-ionone / ionone-series floral fingerprint matched to natural osmanthus (the ratio of β-ionone, dihydro-β-ionone, linalool, linalyl acetate, nerol oxide is the signature)
- 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.
Every lot ships with COA plus GC-MS. We screen synthetic-osmanthus / other flower-wax padding / carrier dilution by the floral fingerprint.
Lots failing the natural osmanthus ionone profile are blocked.
