Separation of the compounds isolated from A. niger was conducted using two different capillary columns. The first column
(BP1) allowed the reasonable retention of the low-volatility compounds; however, other components were not
separated and passed through into the second column (BP10) while the volatile compounds were detected. In Figs. 2 and
3, the chromatograms obtained from nonpolar and mediumpolar column chromatography of the volatile compounds are
