Simultaneous isolation of xanthomegnin, viomellein, rubrosulphin, viopurpurin, and brevianamide A by preparative HPLC. | LitMetric

Simultaneous isolation of xanthomegnin, viomellein, rubrosulphin, viopurpurin, and brevianamide A by preparative HPLC.

Published: March 1985

A method for the isolation of xanthomegnin, viomellein, rubrosulphin, viopurpurin, and brevianamide A from Penicillium viridicatum (DSM 2447) is described. After extraction, HPLC was performed with a preparative silicagel column, eluted with toluene / ethyl acetate / formic acid (27/9/1, v/v/v) and dichloromethane / acetic acid (9/1, v/v). The toxins were detected with a UV-monitor. It was possible to isolate them in an absolutely pure state. The described method is operationally simple and very efficient.
