Each test on this page measures a named compound or group by chromatography: HPLC for the curcuminoids, ar-turmerone and the ginger compounds, and gas chromatography for the total turmerones.
Turmeric and ginger specifications differ in which compounds they name and the basis they use, so tell us yours.
Measures the curcuminoids of turmeric by HPLC against reference standards. USP describes turmeric as the dried rhizome of Curcuma longa and lists curcumin, desmethoxycurcumin and bisdesmethoxycurcumin reference standards for its curcuminoids content. Tell us whether you need the total or each curcuminoid, and the basis your specification uses.
Measures ar-turmerone, one of the turmerones of turmeric, by HPLC. It is a single-compound result, separate from the curcuminoids and from the total turmerones test below.
Measures turmerones by gas chromatography and reports their total. Tell us which turmerones your specification includes in the total.
Measures 6-gingerol by HPLC as a single compound. USP describes ginger as the dried rhizome of Zingiber officinale.
Measures 6-paradol, a pungent phenolic compound related to the gingerols, by HPLC as a single compound. Tell us the material it is specified in.
Measures gingerols and shogaol in ginger materials by HPLC. Tell us which gingerols and which shogaol your specification names and whether it states each compound or a total.
Measures gingerols, gingerdiones and shogaols in ginger materials by HPLC, a wider profile than the gingerols and shogaol test above. Tell us which compounds your specification names.
Measures tetrahydrocurcuminoids, the colorless hydrogenated forms of the curcuminoids sold as white curcuminoids, by HPLC.
Send the material sealed, labeled and protected from light.
Tell us the material, the plant part or extract, and the specification or label claim. We confirm the sample amount at quote.
