Abstract

Two phototoxic compounds, xanthotoxin (8-methoxysporalen) and bergapten (5-methoxypsoralen), were isolated from spring parsley [Cymopterus watsonii (Coult. & Rose) Jones] by thin-layer chromatography, and identified by comparison of Rf values, infrared spectra, and melting points, with pure samples. The concentration of xanthotoxin was two to four times that of bergapten in plant samples collected during the 2-month growing season. Seeds contained xanthotoxin and bergapten in equal concentrations.
