Each test separates the named compounds by HPLC and measures them against reference standards.
Several of these results can be stated as a single compound or as a sum. Tell us the basis your specification uses.
Measures rosavins and salidroside in rhodiola by HPLC. USP describes Rhodiola rosea as the dried roots and rhizomes of the plant and calculates phenylpropenoid glycosides as the sum of rosarin, rosavin and rosin, with salidroside stated separately.
Measures rosavins in rhodiola by HPLC. Tell us whether your specification uses rosavin alone or the sum of rosarin, rosavin and rosin, the basis the USP Rhodiola rosea monograph uses.
Measures salidroside by HPLC as a single compound. The USP Rhodiola rosea monograph states salidroside separately from the rosavins.
Measures glycyrrhizic acid in licorice materials by HPLC. USP describes licorice as the roots, rhizomes and stolons of Glycyrrhiza glabra or Glycyrrhiza uralensis and states glycyrrhizic acid on the dried basis. Tell us whether your specification states the acid or a salt.
Measures kavalactones in kava materials by HPLC. Tell us which kavalactones your specification names and whether it states each one or a total.
Measures kavalactones together with flavokavains in kava materials by HPLC, a wider profile than the kavalactones test above.
Send the material sealed, labeled and protected from light and air.
Tell us the material, the plant part or extract, and the specification or label claim. We confirm the sample amount at quote.
