| Price | Quoted per project |
The chromatographic tests separate the named compounds and measure them against reference standards. The chelidonine UV test is a group estimate, described in its section.
Several of these compounds are stereoisomers or positional isomers of each other. They are separated, and reported individually or as a sum, as your specification states.
Measures yohimbine, an indole alkaloid, by HPLC and reports it as yohimbine hydrochloride where the specification is stated that way.
Measures alpha-yohimbine, also called rauwolscine, a stereoisomer of yohimbine, by HPLC as its own compound.
Measures yohimbine and alpha-yohimbine together by HPLC and reports each.
Measures huperzine A, an alkaloid from Huperzia serrata, by HPLC as a single compound.
Measures mitragynine, an indole alkaloid of Mitragyna speciosa (kratom), by HPLC as a single compound.
Measures mesembrine-type alkaloids, such as those of Sceletium tortuosum, by UPLC. Tell us which alkaloids your specification names.
Measures oxindole alkaloids, for example in cat's claw (Uncaria tomentosa), by UPLC. Tell us which alkaloids your specification names and whether it states each or a total.
Measures alstonine, an indole alkaloid, by HPLC as a single compound.
Measures alstonine and reserpine, two indole alkaloids, together by HPLC and reports each.
Measures flavopereirine, an alkaloid, by HPLC as a single compound. Tell us the material.
Measures alkaloids in California poppy (Eschscholzia californica) materials by HPLC. Tell us which alkaloids your specification names.
A UV estimate of alkaloids expressed as chelidonine, for example in greater celandine (Chelidonium majus) materials. It is a response-based group result that does not identify individual alkaloids.
Measures p-synephrine and m-synephrine (also called phenylephrine), positional isomers, by HPLC and reports each, or their sum where your specification states one. Tell us the material, for example bitter orange extract.
Measures paraxanthine, a dimethylxanthine, by HPLC as a single compound.
Measures theobromine, a methylxanthine found in cocoa, by HPLC as a single compound.
Measures methylxanthines, such as caffeine, theobromine and theophylline, by HPLC. Tell us which xanthines your specification names and whether it states each or a total.
Send the material sealed, labeled and protected from light.
Tell us the material or extract, the form specified (for example the hydrochloride salt) and the label claim or specification. We confirm the sample amount at quote.
