Fig. 2From: Extraction and purification of ustiloxin A from rice false smut balls by a combination of macroporous resin and high-speed countercurrent chromatographyThe effects of different extraction conditions on the UstA extraction capacity. The extraction capacity was presented as the UstA concentration in the extraction solvent. a Different extraction solvents. b The effect of the HCOOH concentration on the extraction capacity. c The effect of the ratio of material and solvent on the extraction capacity; the UstA concentration was calibrated to a constant value by multiplying the dilution fold. d The effect of operating temperature on the extraction capacity. The values of columns with different letters were significantly different (p < 0.05)Back to article page
