Versuchsvorschrift

1.7 g. of crude aculeacins obtained in Example 2 dissolved in 5 ml. of n-butanol was charged on a silica gel column packed with a water-saturated solvent of ethyl acetate-n-butanol (4 : 1). The column was eluted with the same solvent and 10 g. fractions were collected. Each fraction was assayed by bio-assay and thin layer chromatograph to find the activity of Nos. 33 to 55 fractions. Vacuum drying gave 629 mg. of white powder. The powder was further purified by dissolving in n-butanol (50 ml.), and was washed three times with distilled water (each 10 ml.) and dried in vacuo. 577 mg. of purified aculeacin-A was obtained.
