Fig. 4From: Optimization of the production process for the anticancer lead compound illudin M: downstream processingConcentration of Illudin M in extracts of two subsequent elutions from XAD16N incubated with culture supernatant. The gray bars illustrate the illudin M content in the fractions after a first extraction with incresing methanol concentrations. The blue bars illustrate the concentration of illudin M after a second extraction of the resin with 100% methanol. The observed drop at 90% methanol (grey bar) is probably a measurement error since it is not reflected with a higher concentration in the second elution step (blue bar)Back to article page
