High-performance liquid chromatography with photodiode-array detection was used to separate picrocrocin (bitter-tasting component, glucoside of safranal), cis/trans-crocins (carotenoids, glucosyl esters of crocetin) and safranal (flavour, monoterpene aldehyde) of saffron. All components of pure red Greek saffron were extracted from dried
stigma
with 50% methanol. These compounds were detected, separated collected and identified simultaneously using a Merck LiChroCART 125-4 Superspher 100 RP-18 (4 microns) column and as mobile phase a linear gradient from 20% to 100%
acetonitrile
in water in 20 min with a detection wavelength at 308 nm.

A new alkaloid, Canthin-6-one, Huberine (
1
), together with three known compounds including 1-Hydroxy-canthin-6-one (
2
), Canthin-6-one (
3
) and
stigma
sterol (
4
), were isolated from the stem bark of
Picrolemma huberi
. The isolation was achieved by chromatographic techniques and the purification was performed on a C18 column using
acetonitrile
/water (90:10,
v
/
v
) with 0.1% formic acid as the mobile phase. The structural elucidation was performed via spectroscopic methods, notably 1D- and 2D-NMR, UV, IR, MS and HRMS. The antiplasmodial activity of the compounds was studied.
