Kanna testing at Vanguard Laboratory: identity, purity and quantity $250 per sample, with results in 3 to 5 business days.
Marker compound: 2D structure drawn from the PubChem record (CID 394162).
Sceletium tortuosum aerial parts
mesembrine and related alkaloids (mesembrenone, mesembrenol)
total or named markers, as your specification states
botanical ingredient
Marker compounds: mesembrine and related alkaloids (mesembrenone, mesembrenol).
Kanna is extracted and its marker compounds separated by reversed-phase HPLC with UV detection, with LC-MS identity of the markers where needed. Marker compounds are measured against reference standards, $250 per sample with results in 3 to 5 business days. Tell us the basis your specification uses: a total, named markers or a single compound.

Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
HPLC measures mesembrine and the related alkaloids against reference standards, reported individually and as a total.
Yes. Capsules, powders, gummies and liquids are measured with sample preparation matched to the product, and reported in mg per serving or % w/w against the label.
The USP Herbal Medicines Compendium monograph (proposed for development) covers identity by HPTLC fingerprint and an assay of marker compounds by HPLC.
Forms and titles: Sceletium tortuosum Aerial Parts
No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of mesembrine-type alkaloids, with LC-MS identity. The USP Herbal Medicines Compendium monograph for Sceletium tortuosum Aerial Parts is still in development; testing against it is available and quoted.
Mesembrine, mesembrenone, mesembrenol and mesembranol are the main alkaloids in kanna, and their ratio varies with plant source and processing. They are measured individually against reference standards.
Traditional fermentation and drying change the alkaloid ratio, often raising mesembrine relative to mesembrenone. Results are reported for the material as received.
The monograph lists Aptenia species as a potential confounding material. The alkaloid profile helps tell genuine Sceletium from look-alike succulents.
