How it works

The HPLC tests separate the named compounds and measure them against reference standards.

Carotenoids are sensitive to light and air, so samples are handled and prepared to limit that exposure.

Tests offered

Andrographolide content by HPLC

Measures andrographolide, a diterpenoid lactone of andrographis (Andrographis paniculata), by HPLC as a single compound.

Forskolin content by HPLC

Measures forskolin, a labdane diterpene of Coleus forskohlii root, by HPLC as a single compound.

Parthenolide content by HPLC

Measures parthenolide, a sesquiterpene lactone of feverfew (Tanacetum parthenium), by HPLC as a single compound.

Cynaropicrin content by HPLC

Measures cynaropicrin, a sesquiterpene lactone of artichoke leaf, by HPLC as a single compound.

Eurycomanone content by HPLC

Measures eurycomanone, a quassinoid of Eurycoma longifolia root, by HPLC as a single compound.

Astaxanthin content by HPLC

Measures astaxanthin, a carotenoid, by HPLC. Tell us whether your specification states free astaxanthin or includes its esters, and the material, for example algal oil or beadlets.

Lycopene content in tomato extract by HPLC

Measures lycopene, a carotenoid, in tomato extract by HPLC.
