Marker compounds: cinnamaldehyde (CAS 104-55-2), cinnamic acid (CAS 140-10-3), cinnamyl alcohol (CAS 104-54-1), 2-methoxycinnamaldehyde (CAS 1504-74-1)

How Vanguard tests Cassia twig

Method for the $250 identity, purity and quantity test: HPLC-UV marker-compound assay (cinnamaldehyde and related phenylpropanoids), LC-MS identity, against a reference standard, with results in 3 to 5 business days.

The USP Herbal Medicines Compendium monograph covers identity by HPTLC fingerprint and content of cinnamaldehyde and related phenylpropanoids by HPLC. Full testing to the USP Herbal Medicines Compendium monograph for Cinnamomum cassia Twig is available and quoted.

Questions about Cassia twig testing

Is the $250 test the same as USP monograph testing?

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.

Is cassia twig the same as cassia bark?

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.

Is coumarin measured?

Cassia contains coumarin, which is not one of the monograph's phenylpropanoid markers. Coumarin can be added to the HPLC run on request.

Why can cinnamaldehyde results drift?

Cinnamaldehyde is volatile and oxidizes to cinnamic acid over time. Ground material and old stock can show lower cinnamaldehyde and higher cinnamic acid.
