Fig. 6From: Extraction and purification of ustiloxin A from rice false smut balls by a combination of macroporous resin and high-speed countercurrent chromatographyHSCCC separation chromatogram of UstA. The solvent system was n-butanol/TFA/H2O (1:0.05:1, v/v/v). Samples pretreated by MR containing approximately 300 mg of UstA were dissolved in 15 ml of the lower phase. The flow rate was 1.0 ml/min, and the chromatogram was recorded at 254 nmBack to article page
