How it works

The HPLC tests separate the named compounds and measure them against reference standards. Where a title says the result is expressed as another compound, the calculation uses that reference, as described in the section.

Honokiol and magnolol are isomers. The HPLC separates them, and they are reported individually or as a sum, as your specification states.

Tests offered

Aucubin content by HPLC

Measures aucubin, an iridoid glycoside found for example in plantain and chaste tree, by HPLC as a single compound.

Agnuside content by HPLC

Measures agnuside, an iridoid glycoside of chaste tree (Vitex agnus-castus), by HPLC as a single compound.

Casticin content by HPLC

Measures casticin, a methoxylated flavone of chaste tree, by HPLC as a single compound.

Aucubin, agnuside and casticin content by HPLC

Measures aucubin, agnuside and casticin by HPLC and reports each, for chaste tree materials specified on these three compounds.

Harpagoside content in devil's claw by HPLC

Measures harpagoside, an iridoid glycoside, in devil's claw (Harpagophytum procumbens) materials by HPLC.

Acteoside content expressed as ferulic acid in lemon verbena leaf by HPLC

Measures acteoside (verbascoside), a phenylethanoid glycoside, in lemon verbena leaf by HPLC, with the result calculated against ferulic acid as the title states.

Salicin content by HPLC

Scopoletin content in stinging nettle by HPLC

Measures scopoletin, a coumarin, in stinging nettle (Urtica dioica) materials by HPLC.

Phenylpropanoids and coumarin (total) content by HPLC

Measures phenylpropanoids and coumarin by HPLC and reports them as a total. Tell us which compounds your specification includes in the total.

Forsythin content by HPLC

Measures forsythin (phillyrin), a lignan glycoside of forsythia, by HPLC as a single compound.

Schisandrins content by HPLC

Measures schisandrins, lignans of schisandra (Schisandra chinensis), by HPLC. Tell us which schisandrins your specification names and whether it states each or a total.

Honokiol content by HPLC

Measures honokiol, a neolignan of magnolia bark, by HPLC as a single compound.

Honokiol and magnolol content by HPLC

Measures honokiol and magnolol, two isomeric neolignans of magnolia bark, by HPLC and reports each, or their sum where your specification states one.
