Each test separates the named compounds by liquid chromatography and measures them against reference standards.
Citrus flavonoid specifications name either single compounds or groups, so tell us which compounds and which basis yours uses.
Measures hesperidin, a flavanone glycoside of hesperetin found in citrus, by UPLC as a single compound.
Measures hesperetin, the aglycone of hesperidin and neohesperidin, by UPLC as a single compound.
Measures narirutin, a flavanone glycoside of naringenin found in citrus, by UPLC as a single compound.
Measures neohesperidin, a flavanone glycoside of hesperetin, by UPLC as a single compound. Neohesperidin and hesperidin both carry a disaccharide of rhamnose and glucose; they differ in how the two sugars are linked (neohesperidose in neohesperidin, rutinose in hesperidin), so each is measured as its own compound.
Measures neohesperidin dihydrochalcone, a sweetener derived from neohesperidin, by UPLC as a single compound.
Measures nobiletin, a polymethoxylated flavone found in citrus peel, by UPLC as a single compound.
Measures tangeritin, a polymethoxylated flavone found in citrus peel, by UPLC as a single compound.
Measures diosmin, a flavone glycoside of diosmetin, by UPLC. Diosmin ingredients can contain related flavonoids; tell us whether your specification also names them.
Measures flavanones in bergamot dry purified extract by UPLC. Tell us which flavanones your specification names and whether it states each one or a total.
Measures dihydroflavone (flavanone) glycosides together with polymethoxylated flavones by UPLC, a profile of the two citrus flavonoid groups. Tell us which compounds your specification names.
Send the material sealed, labeled and protected from light.
Tell us the material or extract and the specification or label claim. We confirm the sample amount at quote.
