Figure 2: High-speed countercurrent chromatography chromatogram of the Opuntia ficus-indica fruit extracts n-butanol fraction. Solvent system consists of methylene chloride-methanol-n-butanol-water (5:4:3:5, v/v/v/v). 1,000 mg of n-BuOH fraction (dissolved in 5 mL of each phase of the solvent system) was injected; flow rate of 3 mL/min; rotation speed of 500 rpm; retention of stationary phase in (A) and (B) were approximately over 50%
