Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of cinnamaldehyde and related phenylpropanoids, with LC-MS identity. Full testing to the USP Herbal Medicines Compendium monograph for Cinnamomum cassia Twig is available and quoted.
No. The twig and the bark come from the same tree but are different articles, and the bark is usually higher in cinnamaldehyde. This monograph covers the dried twigs.
Cassia contains coumarin, which is not one of the monograph's phenylpropanoid markers. Coumarin can be added to the HPLC run on request.
Cinnamaldehyde is volatile and oxidizes to cinnamic acid over time. Ground material and old stock can show lower cinnamaldehyde and higher cinnamic acid.
