A high performance liquid chromatographic method for the simultaneous determination of bisindole usambarane alkaloids from the roots of Strychnos usambarensis using a diode-array detector is proposed. The system, consisting of a RP-8 Select B column and a linear gradient elution with acetonitrile an

✦ Synopsis
A reversed-phase high performance liquid chromatography method for the separation, identification and simultaneous quantification of sesquiterpenes and polyacetylenes in the essential oil of Chamomilla recutita using a gradient elution programme with UV detection is reported. The structure of (E)-b-farnesene isolated from camomile essential oil was confirmed by nuclear magnetic resonance spectrometry.
